Oil Centrifuge made from $10 Juicer - BLACK DIESEL

[@billnlori3149]

My high school teacher told us he had a grease barrel filled with sawdust. He had a tap at the bottom and would pour his used oil in there. After a while it would start flowing out the bottom and he used it in his mower and other small engines. He claimed it came out looking like new!

At first reading this, I felt it would be BS, but after some "advanced" thinking I wonder if it could act like a simple water filter you make in nature with charcoal, sand and such. But instead of sawdust, iy most likely have to be shavings from wood, and also some kind of screen. Or else it should still come some shavings out with the oil. The great thing with this idea is that when you need to exchange the wood shavings you could use them for easier making a fire.

[@David-f2j4b]

​@@sykoteddy The idea of oil impregnated wood shavings or sawdust has already been experimented with and works great! Think about a hydraulically pressed sausage stuffer that oozes out a continuous long solid "turd" or brick that can then be cut to any length and thrown directly in a fire box.

[@henningklaveness7082]

Speaking as a marine engineer: Your problem is that the free surface effect of the oil creates a fundamentally imbalanced system. Once it gets a little bit off, the oil flows to that side and exacerbates the problem. This is not how marine fuel centrifuges are built; They have a system of concentric cones that he oil has to flow past on its way through, and the system is completely oil filled with no entrapped air. I looked into building my own for filtering vegetable oil for my car, but given the amount of precise sheet metal work that needs to be perfectly balanced, it is by far cost effective to just buy a salvaged unit from a shipbreaker.

[@seenithere]

that kind of sounds like how the old milk & cream separators where built.

[@skunkjobb]

@@seenithere Exactly and that's how marine oil centrifuges are still made. Actually by the same company that invented the milk separator Alfa-Laval.

[@skunkjobb]

Yeah but there's nothing wrong with the basic design of his centrifuge. There are thousands such open bowl centrifuges running perfectly well. I'm sure it's just a question of rigidity here. The bowl is usually turned from a large aluminum billet and the shaft and bearings much beefier.

[@GodAlwaysWins7]

Whats the easiest way to make biod? From what Ive seen I just need lye and methanol.

[@dev-debug]

@@skunkjobb Show me a consumer grade juicer with a bowl machined from billet aluminum, I want to see that price tag lol They generally use a process called metal spinning, same way pop cans are made just different shape and thickness. If you're saying people modified them by machining a bowl out of aluminum and making a more rigid mounting then the juicer is flawed to start with as the OP stated. You could run the oil through a multi stage filter setup with a very fine micron filter as the last stage since those filters cost more. But all this work to burn about a gallon of oil from his car then thinned with gasoline in an old pickup is not worth it.

[@oby-1607]

We have an old Belarus farm tractor that has a centrifuge oil filter installed from the factory. When we went to clean it the walls inside of the centrifuge would have a dry layer of dirt and soot we would scrape and wipe off. Definitely different than the paper oil filaments of today.

[@JustOneFeather]

Когда инженеры Минского тракторного завода проектировали Беларусь, у них было понимание что в стране, где трактор может просто с фермы до поля ехать 20-30 километров, потенциальная поездка за бумажным фильтром машины-технички, которая сопровождает трактор в поле - это потенциальная потеря рабочего времени трактора и тракториста. Хотя и тогда в местных мастерских нередко добавляли обычный бумажный в качестве пост-фильтра, так лучше для двигателя.

[@oby-1607]

@@JustOneFeather Thank you for telling me this as we always liked the system. We did change the oil reularly. We still have the tractor.

[@GoofieNewfie69]

Those older motors will run on almost anything that a diesel can burn. But, in the winter, it's better to have tw tanks, on for diesel and the main for homemade. Start on clean diesel, switch to main, switch back to diesel for shutdown. If you use vegi oil, it helps to have a heater in that the tank. My buddy has a small motorbike radiator in the tank that runs off the motor. He's got a bit of a Frankenstein setup, but only buys about 80 liters of diesel a year for his truck to go about 30,000 kilometers a year, and the temp does get down to -25C , older Toyota fj landcruiser

I knew a guy that ran an 6x6 Army truck off used motor oil. He would pick up totes for free at oil change shops around town every 3 months or so. I think he just filtered it a few times if I remember right. The Truck could run on diesel, kerosene, gasoline or motor oil, engine was designed to run on almost anything and had different settings for the engine that you could switch depending on what you wanted to use. It had good power with the motor oil, that truck could push down big trees and was a blast in the bush.

[@David-f2j4b]

Great video! I laughed so hard when you first fired it up and the imbalance got out of control, because it's ALL part of "experimenting" with a new system! I have been making my own fuels from absolute "junk" since the 1990's and was delighted to see your Volkswagen truck at the very end. I had restored a super lightweight '82 with a turbo eco-diesel I swapped in, along with a long legged 5 speed. It was like driving a go cart and got way over 50 miles per gallon on all the CRAP I fed it. I collected EVERYTHING I could get my hands on, to use as fuel. Including waste oils from engines, transmission fluid, vegetable oils, contaminated ag fuels, furnace oil, etc. I had more than I could ever burn. The key to long injector life and smooth clean running is making as pure a "fuel product" as possible. Centrifuge is GREAT idea but I would pre-purify the oil a little bit more, before doing that step. Let gravity do it's job for a month or 2 in a cone bottom tank, and get out most all of the heavy stuff. Siphon off the top and run through a 5 or 10 micron gravity filter and then centrifuge it. Run that product through a final 1 micron pressure filter system to make it perfect. If you pre "cut" the raw waste oil with a 10 percent solvent like kerosene or gasoline, along with heating it from the sun, it will lower the initial viscosity, and every stage will filter much more efficiently. Take care of that old truck, and feed her the "good stuff" !!

[@KilSmiley]

I like watching all 65's videos to learn what new thing he has figured out. This was the first one I recall getting to see the process of figuring it out. I think it was vastly more educational in the demonstrated challenges and methods he used to overcome them. It definitely had more in the way of entertainment value too, starting with that first "NOPE!" that sounded so familiar to the ones I usually hear coming from my own mouth as an experiment goes sideways in a unexpected hurry. I would have liked to see the one that got cut out, I imagine due to his tourette's that got triggered by the chaos that likely transpired with a quickness. This is already one of my favorite videos from him and I'm only half through. I just had to stop and say this when I saw the comments you made about the experimenting process.

[@David-f2j4b]

​@@KilSmiley Lol, you would have laughed your ass off following me around with a video camera 35 years ago. Before there was Internet, and interest groups, and free easy ways to share information about what works (and more importantly) what doesn't. I was living way off grid making my own power with a trusty old generator in the middle of the woods, with "vague theories" about Rudolph Diesel and his early patent designs and fuels. My early "experiments" with trying to get my expensive diesel generator to run on vegetable oils I was digging out from a dumpster, were "amusing" but eventually successful. I think I had at least 25 jars of various fuel "recipes" going at any given time in various extreme temperature conditions. Once I knew how to reliably make my generator "happy", I made my little antique Volkswagen pickup truck and Jetta happy too. It was a long learning curve, with a LOT of "humorous and labor intensive mistakes" along the way. But this shit WORKS, and I sleep a lot better at night knowing that if the conventional fuel infrastructure of the world fails or disappears, I Don't GIVE A FUCK!

[@KilSmiley]

@David-f2j4b that's incredible. I remember hearing stories about a couple different people back then who would go around to different restaurants grease dumpster to get the fuel for their car on some cross country trips, but eventually the stories just kinda fizzled out. It's inspiring to know it wasn't just a fad that disappeared. I believe there are many different alternatives to the socially accepted "way it's done" that just need some creative thinking skills backed up by a lack of fear of failure. I heard it said before that failure doesn't have to exist if you learn something from the experience and those lessons are the ones that stick with you the longest cause you remember the embarrassing mistake. I know from personal experience the truth of that. It's always good to be able to laugh at harmless errors so you don't take things so seriously that disappointment doesn't prevent the lesson from being learned.

[@David-f2j4b]

​@@KilSmiley you made me laugh so hard I literally choked on my coffee. You mention "Creative thinking skills backed up by a lack of fear of failure" Sounds really good on paper.. I was once a young man, living in the woods on a 40 acre nature preserve. No way in, except on foot or snowmobile. My cabin ran on self generated power, which I used to make, every 3 or 4 days to feed my large battery banks. (This was long before solar was economical to put in.) So I relied 100 percent on my little diesel generator for actual survival. (If that gen set went down for any reason, I got a real life problem real fast.) I had a library of many wise men who had gone before me, men like Tesla and Rudolph Diesel. So I knew quite a bit of stuff about quite a bit of "stuff". And old Rudolph designed his engine and patent theory around vegetable oil fuels. Which interested me quite a bit, because I knew where endless quantities of this waste junk was just being dumped in a big green dumpster about 5 miles away. So I went and got me some of that stinky liquid gold, and put it in some plastic jugs and brought it home. And then I just thought for a few days on how I was going to put it in my precious and expensive generator. So I filtered, and filtered, and filtered some more, until I got it to pass through 1 micron socks. And I kept thinking about Diesel's theory and why this "should" or " might" work. And I had welded up a simple heat exchanger that used the generator exhaust heat to preheat my dumpster oils, and make it thin like water. So after a couple days of just thinking, I was making my usual 2 hour generator run, and all the veg oil stuff was hooked up. And the temp gauge for the oil got over 120F and I had about 5 beers and a little smoke in me trying to get the courage to throw that very last valve. Because turning the last valve cut off the "diesel fuel' and diverted "free dumpster shit" squeezed from vegetables directly into my gen set. Yes there was fear!! Fucking dulled by large amounts of alcohol.. But I did it, because I had already put a lot of stinking effort into this stupid project, and I had to know.. 1 minute 2 minutes 3 minutes Nothing is happening. But I can smell it.. The engine doesn't seem to care that I have completely changed it's diet. It's just fucking stupid.. It doesn't even know... I drink another beer, smoke another smoke, waiting for it to puke, or SOMETHING. But it never does, for another 2 hours. After that, it was testing in Volkswagen's, and those engines were stupid too. They just ate that shit right up as long as it was prepared right. And now here we are on this thing called an "Internet", passing down these "secrets and techniques" to young folk, just like they have been passed down generations before...

Very entertaining Moe. My brother in law collects used cooking oil from the local restaurants and heats his home and hot water with his home made burner. He looked at making a centrifuge but decided to stick with the gravity method. It’s slow but works well as all the gunky sludge, bits of fried food and water settles to the bottom of the 20 litre cans. He lets them sit for a couple of months and strains and pours the clean oil off the top. This gets transferred to a large 250 litre oil tank that used to hold heating oil where further settlement occurs. He’s got a funny set up where he has a 10’ length of 6” steel pipe with a 1/2” copper tube coiled around the outside of it and the whole lot is wrapped in insulation. This was then buried in the ground at a slightly upward angle and the burner placed at the low end. The burner is home made and used an old VW oil pump driven through bicycle sprockets and chain to a small electric motor so the pump runs slowly to drip feeds the burner. He’s also fitted automatic cutouts so if the flame goes out the pump shuts off and if the whole thing catches fire the pump shuts off. Of course all this is outside with the burner in a little shed. It a burns very clean with virtually no smoke but the whole area smells like a fish n chip shop. He’s fitted old school radiators throughout his home and it’s a closed system he has set up with two pipes, the first delivers hot water to a radiator and a second is a seperate return line so every radiator gets the same temperature hot water and he can control the flow of hot water to each radiator individually without effecting the others. He’s a clever bugger but you can tell he’s single by the amount of junk everywhere. Cheers, Stuart 🇦🇺

I noticed after a few days it had seperated and looked like brand new fluid and all the black contaminated fluid and water had sunk to the bottom of the bottle.

I would have thought, you would have just lined the strainer with some nice industrial 1-ply to make a centrifugal version of a Frantz oil filter.

[@sixtyfiveford]

The problem is you can't filter well with filter media. Maybe you can get down to 2 microns with expensive filters but that will quickly clog and you'll have to change out filters constantly. . The centrifuge by itself in this setup will clean under one micron indefinitely.

[@AndTheCorrectAnswerIs]

You can get inline centrifugal oil filters for around $300 (Spincraft and others). You'll need a pump to drive them. I used a power steering pump driven by an electric motor years ago to use my setup to filter used oil to burn in an oil heater. Periodically you unscrew the filter housing and scoop out the accumulated sludge with a spatula.

[@drummer4hire12]

I used Seal-All inside of a cracked float bowl on my dune buggy.......I cannot believe it is STILL holding after 3 years!

[@werner.x]

The reason it's running smoother with oil, is usually due to reduced ignition speed of thil fuel mix. Your injectors opening pressure most likely have dropped to around 100 bar due to the normal spring aging, which means your engine runs with excessive advanced timing (Injectors open earlier than they should) Therefore this hard sound and the improvement with the oil mixture.

[@crzy11000]

This would be useful for someone to run a oil furnace for heating their home in winter. If you are going to try that my friend gets his used oil from the transmission shops as it is much cleaner usually. He then just runs it through several filters. But the addition of a centrifuge would be even better.

[@markusher9975]

The entire rotating must be dynamically balanced! If this cannot be done the rotating mass should be statically balanced before adding the oil. The spinning members are cantilever mounted placing large amounts of stress on the bearing.

If you don't get the carbon out, it will eventually stick to the injector tips (from the combustion - not from passing through the injectors) and cause a poor spray pattern. It will start to smoke. As long as you are OK with pulling your injectors and cleaning them every 500-1000 miles or so, it's not a problem. Some vehicles are easier to do it with than others.

[@sixtyfiveford]

Not true at all. You won't get the carbon out no matter what you try. Literally thousands of guys have documented experiences running WMO well over 100,000 mi upwards of half a million without ever having to worry about coking the injectors. Many of the guys don't do anything besides pour straight into the fuel tank directly after draining it from the motor.

[@sykoteddy]

@@Mikefngarage I'm sorry to hear that, I'm not great at car mechanic stuff, I've only filtered veggie oil for my friend. You must make sure to heat up the veggie oil when it gets too cold. Many say you need to have 2 tanks, one with regular diesel and one with veggie oil so you can start up the car on regular and change when it's warm. Try to use a ultrasonic cleaner and be sure to use hot water or some solvent that is preheated. I sadly don't have any other idea's.

[@d.j.9961]

I saw a video where supposedly, a water filter cleaned used oil. Something such as a pitcher filter like a pure pitcher filter. Worth trying.

[@sixtyfiveford]

The issue with filters is the clog easily and the cost generally offsets the savings. The centrifuge filters to a much greater degree and aren't a consumable. Generally a filter will go down to 10 micron or if you pay a lot more maybe 2 micron. A centrifuge is known to filter under 1 micron.

[@488ci]

Absolute genius 👌

[@David-f2j4b]

For next video we want to see a scaled up version!! Do a washing machine on ultra spin cycle, filled with concentric layers of different kinds of "filter material". (maybe take suggestions from your audience) A course grade inner circle of 100 microns where the oil is dripped in, and proceeding through various reduction sizes until it gets to 1 micron (or less if you can do it) at the high speed outer ring. Rig up a variable voltage transformer off your 240v mains, and keep cranking up the input voltage and consequential spin rate, to observe the resulting flow and filtering characteristics and efficiencies, as it relates to increased RPM's and centrifugal forces. Keep pushing, keep pushing, until you find the precise point of failure, and the whole thing blows apart under extreme load!!! The rest of us can learn exactly WHERE the critical "point of no return" occurs, as it relates to common household centrifuges. (Be sure to Wear safety googles in case of KZbin rules, and to set a good example for the "young folk" who may be watching)

Others have said that a milk/cream separator does something like this. Not sure how common those are.

[@David-f2j4b]

I have been fascinated with those centrifugal creme separators since I was a kid and used to hand crank the one my grandmother had. Very cool machines with a high spin rate, even if you do it by hand. They are very common and easy to buy if you are from a "dairy state" like Wisconsin or probably all over the Midwest. 50 to 300 dollars will easily buy a nice working antique. They have about a 6 inch stainless centrifuge, perfectly balanced and mounted on heavy weighted cast iron fixture. Your kids would love it.

[@savage6394]

If only you had released this video 4-5 days ago! I found a big Centrifuge in a dumpster but it was too heavy for me alone to lift out of the dumpster. It was like 30” x 30” x 14” probably 160-180lbs. I was going to have a buddy go help grab it but got busy with family. Ps. I'm here in Salt Lake City

[@loco0351]

Part of the problem for the vibration is the metal you added. It has thrown the balance off. The fluid is supposed move throw the little holes you covered. A home made filter of some sort placed around and have the centrifugal force move the oil and filter it that way. It might have been easier with less problems. Oh and using rubber mounts to along with the screws would also help with the vibrations.

[@whoreallycares8129]

You always seem to cover interesting topics. I think I already watched the VW Truck video but it came up so I'll give it another watch. I have an 84 Mitsubishi turbo diesel and about 25 gal of used vegetable oil that I'm going to run 50/50 with diesel. Any thoughts, experience or concerns using veg oil. I've used the used veg oil and it is true that it smells like French Fries! Thanks for the video and ideas and keep up the good work. Oh yeah, I think I seen you do the air valve to spray can mod - I did that and it worked fine. Just avoid the brass colored cheap Chinese valve stems that aren't really brass at all - not good... Thanks!

[@sixtyfiveford]

No personal experience, only stuff I've researched. Waste Vegetable Oil or as the forums call it WVO is way stickier, gummier, and has glycerin's that like to gum up stuff. You can actually convert it to a way cleaner product with some lye and a little ethanol if I recall. Ends up removing all the glycerin and costing under a $1 to make very usable fuel. Of course every diesel engine is a little different and some don't ever care what they ingest. Personally I would feel comfortable at maybe up to 20-25% without doing anything and only in warmer months. Yes I found out about the brass colored not brass valves. I had no idea they did this until a year or so ago.

[@GHOST-GXZ]

I've read that the carbon that makes it into the oil doesnt get trapped in the filter

[@TimSpaw1leg]

Wonder if the lid can be modified, and modify an oil filter to bolt down on the inside under that nylon nut... to filter under the centrifugal force.. or maybe the filter will throw it off balance even more.. Or use micro screen instead of soda cans to filter it under centrifugal force.. the ideas are flowing now..

I will also add that running these types of "fuels" are more tolerant in older, fully mechanical type injection systems with no computers and sensors involved to complain about what you are feeding it. OLD TECHNOLOGY IS RELIABLE and more simple to maintain!

[@brizzx32]

21:15 After removing the grit I wonder if the oil can just be reused in your car?

[@neptarclepuffin]

If you are having balance issues just reduce the centrifugal mass... AKA use a shorter spin disk, to do this cut the wall half way down cut a slit in the discarded piece fit back in place (On the inside if done to outside of spinning rotor it will detonate) jb weld or use desired glue. I would jb weld those holes and thin it out by pressing a piece of paper against the holes and that slit you made then rebalance again after it dries of course. Only reason why you would be slinging that much oil around will be if you are seperating literal pounds of insoluble solids. Remember you are only separating different densities with that gravity separator.

[@CrimeVid]

And what is your juicer's intended duty cycle ?

[@mickwolf1077]

The oil will only find it's level in the centrifuge, the drum has to be balanced still. I think if you ran many batches of wmo through it then you'd notice a lot more gunk left over.

[@jackmahogovv]

centrifuges can spin the carbon out. Look at centrifuge bypass filter. Most of them are powered by oil pressure. Maybe try one of those with a pump. Not sure how many passes through it would take to come out clear, but it does turn it clear and you can reuse the oil if it tests good. It leaves a ring of "cake" in the filter drum.

[@sixtyfiveford]

Yes, but those have the filter media as a consumable. They are just using the G force to press the oil through the filter. They're not really using the centrifuge like their intended. Your talking a $10,000+ investment for a setup like this and really only pays off on huge scale.

[@warrenkernot4522]

I agree the bottom of the hopper may be flexing!

[@jp34604]

What makes you think that covering the holes was necessary? If you left it the way it was, it would work perfectly, imho.

[@crzy11000]

Here are my 2 cents. If you put some small ball bearings in the juicer like they use to self balance a tire would it work better? I would also have started by running it as a juicer and then measure the weight of the contents of the juicer(pulp) and see how much oil in volume would be a similar weight. That calculation might give you a better idea of the max weight volume the machine can handle. The manufacturer might have used this calculation in the designing of the juicer. You could then try and strengthen the bearing holders in the base. My other thought was to manufacture a nut to replace the nylon one with a shaft out the top of it which could be held by the lid as an extra bearing surface add a cheap bearing to inside of the lid for it to seat in. You would probably need to machine that new nut so it is in balance. You might be able to design it in software to print in a 3d printer.?

[@charlescanton4740]

This is from the ONION, right? I suppose this short duration spin will isolate any large chunks circulating in the oil but there is no way I'd put that "recycled" oil into anything other than a smudge pot. I certainly would not put it into a Diesel engine. Oil (lubrication) is the life blood of a machine and oil is the cost of reliability. Diesel injection systems are high precision systems that rely on the lubricity and cleanliness of the fuel for durability and reliability. For added content value repeat this 'experiment' in your partner's kitchen.

[@David-f2j4b]

Thank God my old antique Volkswagen diesel Rabbit doesn't have a clue it's such a sensitive high precision machine!! After feeding it a diet of homemade fuel for many many years, it still bangs happily along without a care..

[@oBseSsIoNPC]

The reason they use clap boards is to have a visual and audible que for aligning sound. You should do this as well, to make sure your audio and visual is in sync. None of your problem that people like me get triggered heavily by such small discrepancies, but it just makes for much higher quality content. Anyway. Not a bad start for filtering old oil.

[@jdaniel11405822]

Instead of a can and glue, could you use aluminum tape? Or what about magnetic tape on the outside to help trap the metal?

[@sixtyfiveford]

The oil will break down the adhesive on the tape and it will just pour out. Virtually all the dirt and metal particles are not magnetic.

[@tiredironrepair]

I'm amazed it works at all since according to Newton there's no such thing as centrifugal force but actually centripetal force that pulls inward. The "apparent" outward force is said to be the result of the mass in motion traveling in a curved path, and the outward pull is the result of the mass's resistance to change of direction when traveling in a curved path. Centripetal force is described as the force keeping objects in a curved path. The examples given are orbiting bodies in outer space, turning a corner in a car or a merry go round or spinning water in a bucket etc. So no outward force but an inward centripetal force drawing towards center that is felt as the tension in the bucket handle or many other "apparent" centrifugal forces. I realize this has nothing to do with the oil cleanup stuff, which is great by the way, but I was wondering if anyone else had the feeling that "centripetal" reeks of scientific BS? I'm fairly sure that the contaminates in the oil are moved outward due to greater mass by centrifugal force and not by an inward pull of some kind. Please comment about those forces if you like. Great video and thank you.

[@David-f2j4b]

Ya..maybe..but what did that Newton fellow really know about juicers? Show me the math... If I was on a merry-go-round in space, orbiting the earth at a constant velocity, and sitting on a counterclockwise rotating chair while holding a juicer that was spinning clockwise at 10,000 RPM, would Newtonian Physics break down? Are we still talking about purely centripetal or centrifugal forces, or possibly a combination of the 2 ??

[@tiredironrepair]

@@David-f2j4b Good point! lol Idk?

[@David-f2j4b]

@@tiredironrepairI am still struggling with the equations for the above mentioned thought experiment. It was not described whether the merry-go-round was in a "normal" prograde orbit, or is it going backwards "retrograde", in relation to earths spin? And does the spin rate and direction of the merry-go-round in a vacuum environment have any effect on the purity of the oil coming out of the juicer? My calculations don't make sense to me if I change that variable. I am still trying to determine if the resulting centrifugal forces are greater than centripetal forces, or if they actually cancel each other out and are essentially equal? Sometimes a juicer is just a juicer, as Freud once pointed out. (Wink wink nudge nudge)

[@tiredironrepair]

@@David-f2j4b Literally Lol. Cracked me up. I guess my real question of all the centripetal force explanation is how and why they've concluded the force is exerted inward based on a mathematical calculation when the only way we observe and experience the force is an outward pulling force. The equation to calculate the force seems ok but to say it is pulling inward, holding an object in a curved path and it's resistance to a changing direction that we perceive as an outward pulling force seems like a fundamental lack of understanding the evidence of our senses. Or an intentional misdirection to confuse the issue. Gravity can't hold water on the Earth without centripetal force to mathematically back it up as far as I can tell. Thanks man! I literally laughed out loud. Good comments!

[@David-f2j4b]

@@tiredironrepair I couldn't fall asleep last night because I realized that I had missed a HUGE variable in my calculations! The entire "system" of juicer, rotating chair, merry-go-round, and reverse retrograde low earth orbit, is also being acted on by outside centripetal and centrifugal forces, because of our trapped elliptical and variable velocity orbit around the Sun!! Which is centrifugally acted upon by it's rotation around the Milky Way, and that whole system is rotating around still another distant point in space time...... I think I am going to have to ask for some help from AI, because these calculations are getting beyond my ability to give you a definitive answer one way or the other. I am sorry. 😔 (Happy to make you laugh. Your questions are legitimate. I was hoping you wouldn't get pissed off thinking I was poking fun.

My solution would be a 1 micron filter sock material in the centrifuge, and drip feed that as it spins. Then the entire sock can be easily removed along with all the contaminants with it. But I would settle and rough pre filter the contaminated oil first, to maybe 10 microns, to help the final 1 micron sock last a lot longer. .

The standard centrifuge like this filters to under 1 micron.

Do you need a really old diesel engine like in your car for this to run properly?

My personal opinion is that it's easier to run "junk fuels" in older engines like Volkswagen and Mercedes, BEFORE there were sensitive computer systems and sensor variables to complicate the whole injection process. Old engines with pure mechanical injection are just "stupid and happy" and well built. Volkswagen complicated their TDI system around 30 years ago or so. The beauty about older engines is they are easier to work on and parts are cheap. Maybe some younger guys are running new stuff with great success, I don't know. I am an antique too, and all my machines are old just because I keep it all running, and it never wears out..

[@sixtyfiveford]

Older is better or is it just better known.....? Generally people don't like to mess with stuff until it's all paid off and barely being kept alive. Then you have nothing too loose. You'll find countless post where people ask the same and the resounding answer is " is it worth the risk? It'll cost so much $$ if it fails"

[@David-f2j4b]

@@sixtyfiveford Yes, I agree that most people don't want to "mess around" with the complex fuel system of a modern machine until it's paid off, and out of warranty. That makes economic sense. For me personally, all my machines were completely paid off at time of purchase, and long out of warranty, although still running perfectly. I was primarily interested in "can I make this thing CHEAPER to run" and can I control my own fuel infrastructure from beginning to end, in the event of an "emergency situation". When I started down this path, ALL the engines were old, non computerized technology. So that decision was already made for me. I also think a person's "personality and skill set" has a lot to do with even trying this, whether in an old or 'newer' engine. Some people just should NOT color outside the box under any circumstances, because you can get in way over your head and it WOULD cost big money to get out again. Not everybody has 2 or 3 extra injection pumps and a dozen injectors laying around in inventory. If you can't clean a pump or injectors, and correctly time a diesel, maybe you shouldn't mess with this stuff. Some "personalities" just get great satisfaction from trying new things, to see if it "works" or not. That's a reward in itself. If you can do all your own work, and get a good "system" going, there is definitely an economic reward too.

​@@sixtyfiveford Just ran across some interesting information, in regards to the "old versus new" engines. I have no actual experience with this myself, but just passing it along as something to possibly consider. I have to look into the technical details a little more to see how this is working.

So I'd love to hear from those guys who are trying this, with those engines..
