Make "Biodiesel"? Let’s find out! Diesel vs Biodiesel, Used Motor Oil, Vegetable Oil, MPG

Biodiesel vs diesel, used motor oil, diesel, and hydrodiesel. I bought a diesel engine for testing different alternative fuels. We’ll see how it runs on straight diesel, used motor oil with 10% gasoline, biodiesel, vegetable oil, and hydrodiesel. Please let me know if you'd like to see a comparison of MPGs / fuel efficiency. A BIG thanks to Matt from the Warped Perception KZbin channel for sending the hydrodiesel to me for testing. Also, thank you for supporting the channel, which allows me to decline all sponsorships to ensure unbiased testing.

@Alex Fracyon I use 2-stroke oil as additive in my old tractors. Many injection pumps are lubricated by the fuel and a little extra lube makes many of them run smoother.

[@danieljones317]

Has there been any research on untreated vegetable oil on engine efficiency, long-term wear (including seals), etc.? Thanks

[@ThatKiltedGuyDIY]

As the author of a book about bio diesel, called “The do it yourself guide to biodiesel”, I’ll add some interesting notes here. As always, a good video. Even though I wrote the book 15 years ago and haven’t mastered biodiesel in about six years, I think I can still remember most of it, LOL. Cooking oil is a triglyceride, meaning it is a large glycerin molecule attached to 3 fatty acid molecules. When the methanol and catalyst (either Lye, or potassium hydroxide also known as KOH) are mixed together They form a very caustic solution. When that is added to heated up cooking oil and agitated it breaks the bonds causing the glycerin to drop out. You don’t want the glycerin because glycerin doesn’t burn well and eventually gums up engine parts. That’s why SVO, or straight vegetable oil is less than ideal (Because the glycerin is still in it). And biodiesel is not just cooking oil with chemicals added, it’s actually a new chemical substance because of this whole process. Water washing works really well, but you actually need to remove the remaining water from the bio diesel which is why it still looks cloudy in the video. I used to do it by spray drying. When it’s truly clean it will be very clear, although it will still have a tint anywhere from Amber to yellow. I ran biodiesel in multiple engines for years with not one problem. It can’t be winterized like petroleum diesel and will gel as shown in this video. That and the fact that due to the way modern diesels are designed, you can only use a maximum of 20% in the engine if at all, so I finally gave up on using it because I like to drive modern vehicles. I never liked the idea of straight vegetable oil, known as SVO, because the glycerin is still in it which causes problems with sensors, and general gumming up. And you had to have an oil heater to get it to flow properly, and then switch over once it warmed up, and that was even more difficult in the winter so it has huge drawbacks. But I used to make it for $.35 a gallon which was great in 2008 when fuel prices hit $4.00 a gallon. But what actually determines the price is the methanol. You can usually find cooking oil for free, but the price of methanol is what will determine the final price. I used to buy 55 gallon drums of it from my supplier for a good price. My diesel truck as well as my fathers and our tractor all ran smoother and quieter on biodiesel so I miss it. My current channel focuses on teaching home-improvement skills with a focus on drywall. I just recently received my silver play button for 100,000 subscribers so I don’t get too involved with bio diesel anymore.

[@joeyahoo2438]

Great explanation Kilted! I too have been involved in making B100 for both of my Mercedes-Benz Diesel cars. The process is exactly as you described. My friend has a processor, and we make 80 gallons at a time. He has solar power, so the only hard costs are the methanol and KOH. We can make it for less than $1.00 a gallon!

[@davidscott5903]

Can you describe the spray dryer?

[@BrodieBr0]

Thank you for the info! I am the opposite and run all older vehicles and equipment on my farm and am going to run biodiesel in the warm months.

[@ThatKiltedGuyDIY]

@@davidscott5903 well basically you’re trying to gently spray the bio diesel out in as wide of a pattern as possible which exposes the fuel to more air & the air slowly evaporates the water. When it is finally dry it will go from that milky hazy look to crystal clear almost instantly. It will still have color to it just not the haze. I manufactured the equipment for six years under the name EZ biodiesel and had connections to nozzles that would spray in a nice flat pattern. A lot of people just use a garden sprayer nozzle or something like that. I have a second KZbin channel that I just now started with no videos, called That Kilted Guy Creates and I may do an example of how to make biodiesel the way I used to. I had mine tested once and it came back very clean.

[@spazzwazzle]

What is it about modern diesel engines that makes biodiesel not work? Emissions, or something to do with the newer injection systems?

[@Jerry-pk7xw]

Been making Bio-diesel since 2007. Very easy to make. Tip : pre-treat your next batch of WVO (60 deg c for 1 hour) with the glycerol of the previous batch. Will lower Titration, increase yeild and clean out most of the glycerol from the remaining methanol and KOH ( I use KOH).

There used to be a whole scene of people in Germany doing this, they called themselves "Pöler" (from PflanzenÖL = Plantoil).

I change car (long lease) over 2-3 years and I do around 60000 km for year. I make a lot of experiments with vegetable oil. Using your system( change fuel on start) and using pure vegetable oil, I find that the mileage without problems is around 40000 km. After, issues come often : valves, turbos, and other things. Considering the fuel consumption is more about 5% with vegetable oil, the convenience is when the vegetable oil price is under 10% minimum above the diesel fuel. And now, in Europe, the diesel fuel is around 2 € for liter, and vegetable oil is around 3,5€ due to the war in Ukraine. So I suggest to be careful with pure vegetable oil

The type of vegetable oil used does seem to make a difference in the lubricity of the fuel product.

Interesting study. I'm sure it is out there somewhere on the Internet if a person did a search for it. Great video, thanks!

[@AndrewHutton]

The engine isn't the main issue. The big problem people see and blame on fuel type is corrosion, usually from biodiesel that has not been dried enough or left in such a way to allow it to absorb moisture as water dissolves in biodiesel compared with diesel where it sinks to the bottom. Proper drying and a water absorption filter at point of dispensing are critical.

In the oil refinery industry the extra step to remove the sulfur from diesel at that low part per million also strips some of the lubricity components in diesel. This is why many believe the myth that sulfur is a lubricating molecule. Sulfur does not lubricate but the process of removing it reduces diesels lubricity index.

idk the long term drawbacks of biodiesel are, but i can assure you running older diesel engines live a long time on filtered used vegetable oil. about 9 years ago i turned my wrecked VW Tdi car into a generator for our home instead of fixing it back up to be used on the road. It had 286k on the odo back then and since converting it multiple versions of our home backup generator, its been running on filtered used vegetable oil for just over 7 of those years. I have it setup on a dual tank setup, starts and stops on normal diesel, but shifts to used vegetable oil once the temperature of the oil has reached 150f, which is heated by the engine coolant. I filter my oil with a centrifuge filter system, because the cost of filters got pricey and is easy to clean out, but I use denim jeans as my garbage prefilter, because i can get them from the local thrift store for free in large quantities. I get my oil from local mom and pop restaurant for the past 7 years and have managed to accumulate more than 2500+ gallons of the stuff in 10 IBC totes I have sitting in the barn. I have thousands of hours of run time on this VW TDI engine running off the SVO over the course of 9 years as i use the setup to self power its filtering process via a mechanical pump and engine coolant circuit to thin the oil out during filtering. My latest version of the setup runs DC motor heads, which directly feed my solar system to charge the batteries with direct DC instead of going from AC back to DC to charge the batteries and run my home.

old diesel tech (indirect injection, or electro mechanical one from the 80s) are the best if you want to run vegetable or motor oil. 2 key charateristics : A strong enough injection pump and a powerfull fuel warmer and engine pre heating system

[@ProjectFarm]

Thanks for the feedback.

[@jhsevs]

EDC rotary pump diesels from the early 00s are also good. Just stay away from anything that has a Lucas rotary pump. Bosch Verteiler pumps are good. Inline pumps (like on mercs) are even better, because they use the engine oil for lubricating the injection pump, not the fuel, so the lubricity of the fuel doesn't matter and they're really tolerant.

[@jhsevs]

@@ProjectFarm Also, very interesting to see the lubricity test. I've always wondered if veg oil could be used as an alternative to motor oil in a brand new engine that hasn't seen any oil yet. Perhaps along with some of those oil additive bottles you can buy. One theory why veg oil doesn't work in a (warmed up) engine is because veg oil reacts chemically with the old leftover oil that is in the engine, causing either bacteria/algae, or polymerization (creating rubber like plastic in the oil). I'm not sure if completely brand new engines come completely free of oil though, as I've never bought one. Presumably so, since you had to bleed the fuel system? Would this be a good video idea?

[@jeffmccrea9347]

I would apply great caution in using "hydro diesel" in ANY diesel engine that you want to use for years and years. As you know, (and this is more for your viewers who don't know), ALL piston type internal combustion engines have piston rings. These rings have gaps in them to allow them to be placed in the grooves in the piston. A properly built engine always has these gaps placed opposite from each other to cut down on compression blow by. Note I said "cut down". They do not stop it completely. I can't speak for consumer sized vehicle diesel engines but I do know that tractor trailer trucks use their 11 gallon oil supply for anywhere from 10,000 to 25,000 miles. BTW, did I mention that most, if not all diesel powered vehicles and heavy equipment have WATER TRAPS in their fuel lines? There's a reason for this. Not only is it a good idea to keep water out of the fuel system in the winter to prevent icing but also if there is water in the system and it separates and gets into an injector line, it doesn't burn well so you can scratch that cylinder's contribution to the cause until you bleed that injector line or entire fuel system depending on how much water is present. My main point with the oil is if you have water constantly in the fuel, it will eventually find it's way into the oil past the gaps in the piston rings thereby diluting the oil and reducing it's lubricating quality. I started driving 48 years ago just before the Arab oil embargo. Not long after, I started seeing advertisements hawking a bubbler setup that you installed in your power brake vacuum line or PVC line if you didn't have power brakes. You were supposed to install this glass 3 or 4 quart jar under the hood, add water and this "secret" formula liquid that was nothing more than pink stained methanol. It was supposed to use the vacuum to draw air into the jar to produce water bubbles to be sucked into the combustion chamber of "any gasoline engine". The idea was to inject a non-combustible substance into the combustion chamber to take up space thereby increasing the compression ratio and resulting higher horsepower and better gas mileage. Yeah, how'd that work for you? It, of course, was a fraud for several reasons: 1) If the "bubbles" were even able to survive the trip up the hose, most of them would surely pop when in contact with the intake valve. 2) If the bubbles survived past the intake valve and did what they were supposed to do, increase compression, this would cause your engine to knock thereby raising the octane requirement of your engine meaning that you now have to burn more expensive premium gas or retard your timing and reducing the horsepower, gas mileage and efficiency of your engine to even lower levels that in the beginning or risk engine damage from detonation. 3) If nothing else, you are now introducing water into your engine where it doesn't belong and giving it a path into your oil past the piston ring gaps mentioned above. There's a reason that oil companies don't add water to their petroleum products. God knows that they would make more money if they could as water is cheaper than crude oil. Not to knock your friend who produces hydro-diesel but it almost sounds like the bubbler deal. You can't use the bubbler on a super or turbo charged diesel as the intake has positive air pressure so no vacuum to make it work. It almost sounds like hydro-diesel is meant to increase compression like the bubbler but in a diesel engine that already has proper compression, increasing it more could mean that you would have to lower the cetane rating of the fuel to slow down combustion or risk head gasket, piston wrist pin or connecting rod bearing damage. 15:1 or 20:1 compression is stressful enough and diesels are built for this. Increase it much over this on a long term basis can also stretch head bolts which over time can lead to head gasket failure. I'm NOT saying that hydro-diesel is a fraud and it might actually be beneficial in an older diesel engine with less than ideal compression. One that you would plan to get rid of when it finally quits. If Hydro-diesel was all that was available to get you down the road, I'd use it and flush it out as soon as I could get regular diesel fuel. Keep using hydro-diesel if you wish. All I can say is somewhere down the road, if I see you with your thumb out, I'll be happy to pick you up and take you to a shop.

[@2009dudeman]

Hydrodiesel is an interesting fuel, I would not be so concerned about water in oil at least at the rates it would be seeping past the compression and intermediate rings. I would instead be more worried about settling of the hydrodiesel much like water in regular diesel. Hydrodiesel is supposedly designed so that the water is encapsulated in some coating that prevents direct contact between the water and other parts inside the engine. What I do not know is what the properties of this film are and how they handle wear. Diesel fuel is the lubricant for injection pumps and injector bodies alike, gasoline is so harmful because it's a crappy lubricant comparatively and is like running an engine with water in the crankcase instead of oil. My concern would be the wear on injection pumps and injectors, common rail systems operate from 15,000psi all the way to 60,000psi and were designed to operate with diesel fuel specifically. The tolerances, materials, and even shapes are designed for the lubricity and viscosity of diesel fuel, not an water in oil mix (which is what they call it). I guess if you ran your oil for a long time you could have a problem, but the rate at which water would evaporate from the oil is pretty high. Even in the winter when i'm running down the highway my return oil temp from the oil cooler is up near 150 degrees F, in the summer it will regularly hit 190-200 degrees on the oil return temp. Cars and trucks around here can have problems in the winter on longer oil change intervals if they only take short trips and their engine oil never warms up, they will actually get water in their oil from condensation. Just take a nice drive every now and then and that problem is solved. Maybe long term use might have some effect if you ran long oil changer intervals like 8,000 miles or more, but on diesels running 3-5k on an oil change I don't think it's a big deal. Though I would be curious to see someone try running it for an entire oil change then having an oil analysis done on it.

[@jeffmccrea9347]

@@2009dudeman For the record, everything I spoke about regarded big trucks. Not pickups or cars. Mercedes was the only car in the country then with diesel. What you say makes sense and I have to admit, in my old age, I am working on 40+ year old information. I took a 2 year course in diesel mechanics from 1974 to 1976. From what I learned back then, paraffin and sulfur in the diesel fuel was the injector lubricants because diesel fuel isn't much more viscus than gasoline. Large truck fuel injectors then were kind on like a large steel plug that went into the cylinder. It had a pin inside that was under a high pressure spring. This pin had a cone shaped point on the cylinder end that fit into a matching hole. The tolerance then was .0015 inch. Hence the need for extremely clean fuel and no air in the system. The high pressure mechanical fuel pump would force fuel down past the pin to the point where it would push back on the point allowing the fuel to atomize into the combustion chamber. When the pressure came off the injector, the pin would drop back into the matching hole and the back pressure through the injector nozzle wouldn't be enough to leak compression pressure back to the pump. I am not sure if this configuration has changed significantly over the years. I know that low sulfur diesel is now the law and pollution standards were just coming into existence at the time. Back then, Heavy duty injectors on new trucks had limiters on them to prevent rolling coal but marine injectors required no such limits so some owner operators would risk voiding their warranties by installing marine injectors. I remember when we laughed at our teachers when they said computer engine controls were coming soon. Yup. I can see where water in diesel can cause the problems that you mention. From what you are saying, I assume that you have a diesel in a pickup or car bot correct me if I'm wrong. While both automotive and heavy equipment diesels function basically the same, there are some differences. While automotive diesels use what 5 to 8 quarts of oil, Tractor trailers use up to 11 gallons. While this may have changed some, I don't see that it would be by much. Over the 1 to 2 million mile life of an industrial diesel, if serviced properly, changing it's oil every 3,000 to 5,000 miles would get extremely expensive in a short time. a 1 million miles and 44 quarts of oil changing it every 5,000 miles is 2,200 gallons of lube oil. Big trucks in my day, at least, had oil change intervals of 10,000 to 25,000 miles as the added volume would be more forgiving of contaminants like ash and water. I have seen the damage that water can cause to bearing surfaces in engines. It's not a pretty sight. Yes, water can evaporate in a hot engine but in the 50 or so years that the road draft tube has been replaced by the PVC valve, once the water evaporates, is has nowhere to go but to condense back onto cold engine parts and back into the oil. When fuel and oils were high in sulfur, There was also a problem with water mixing with the sulfur to make sulfuric acid in the oil. In the short run, this was negligible but if a truck sat more that it ran, as you mentioned, it would add to the damage of bronze bearing surfaces pitting them and making them spongy on a microscopic level. On job that I had years ago, they had what they called "the yard dog." It was a single axle, dual tire tractor with a hydraulic lift and an air release on the hook on the 5th wheel. It also had a back door out of the cab. It wasn't made for the road and never left the property. What it was for was to jockey trailers in and out of the shipping doors if a company driver / truck wasn't available. It was a real time saver. Instead of backing up under the trailer, connecting the air hoses, cranking up the landing gear, backing into the door, cranking down the gear, disconnecting the air hoses, pulling the release and pulling out, you backed under the pin, pull the lift lever and lifted the gear about 8 to 10 inches, step out the back door onto a small catwalk, connect the air hoses, jump back in and back it into the door. Let the lift down, step out the back door, disconnect the air, get in, push the air release and drive away. In and out in 3 to 5 minutes if you know what you're doing. They had me do this some times as I was the only one on the property on that shift that could drive a truck if the regular guy was out. This is the type of truck engine that suffers from lack of service as it never gets hot and no miles hardly for years so the oil might stay in it for 5 years before someone thinks about it sitting in the yard quietly.

[@2009dudeman]

@@jeffmccrea9347 I was a diesel mechanic on class 8 trucks for awhile then an auto mechanic, before my shoulder gave out and I would lose feeling in my fingers. Not too much has changed in modern diesel injectors, they still use a poppet valve on the injector tip, most are electric actuated. Most diesels are going common rail now, which is slightly different from the old mechanical pumps you are used to. The main difference is that instead of a different port and line on the pump for each cylinder there is one port on the pump and a big fuel rail that runs the length of the engine where each injector taps into. This is fed by a traditional enough injection pump, usually a gear pump at pressures between 15,000-60,000psi. When the ECM decides to fire an injector it sends a electric signal to the injector and a solenoid forces the plunger open overcoming spring pressure. The rest is pretty much still the same, minus some nozzle design changes and multiple injection events per combustion event. As far as diesel lubrication they still use paraffin, but in place of sulfur they now use several other additives that perform various functions from cleaning to acid protection, etc. Diesel oil has also significantly improved, the additive packages they put in it now are night and day from old oil. They have corrosion protection additives that prevent the acidic blowby gasses from making the oil acidic, to cleaning dirt and grime buildup, as well as some emulsifiers to help dissolve water and prevent small amounts from pooling, mostly if you are in cold climates. Not that I would ever use hydrodiesel, if it really was that good then everyone would be using it, and I think you are right that in a big truck it would cause problems. They are pushing oil change intervals on them to ridiculous lengths, I have seen 40,000 mile oil intervals on some road trucks. Course I think those ones took 18 gallons and had oil life meters. But in a regular small diesel like a truck or lawn tractor, it shouldn't be too much of a problem for the internals of the engine, they tend to get pretty hot thanks to emissions in trucks. I'd still be worried about the injectors and injection pump, those tolerances you mentioned have only gotten tighter and I would be very hesitant to put water in there. Hell, most of the newer trucks would get mad and start throwing codes if you used vegetable oil or used motor oil they are so sensitive and some have fuel sensors that measure the conductivity of the fuel to make sure it's good. Most all trucks use some form of crankcase ventilation, whether it's positive ventilation or a breather vent, they all run back into the intake and air is being quickly cycled through the crankcase. Vapors in the air are more likely to form from outside air once you shut it off and it starts cooling down. This goes for both small and big trucks. Though long periods of idling are killer on diesel engines, i've seen trucks come in with almost a gallon of diesel fuel sitting on top of the oil because they idled in the cold so long it started to wash down the cylinder. I'd never put hydrodiesel in a big truck for exactly that reason.

@@2009dudeman WOW, now you have made me feel like I wasted two years of my life. 😂 Just kidding. It has been a long time since I was in the diesel repair business. The original plan for me in the 70's was to take the diesel course as a preamble to a car mechanics course that had a 2 year waiting list. Car mechanic was my primary goal and we figured that if I took the diesel course, it would help me breeze through the car course due to the commonalities between them. I got tired of school after the diesel course and resigned myself to that but even that got old after a while so as you can see, I didn't keep up with improvements over the years. Where I said that you made me feel like I wasted 2 years was sort of stagnation on my part. If I had gone from the course that I took and moved directly into a school teaching what you said here, I would have said that it was all wrong but then that's what we said in 1974 when they told us that ECM's were coming soon. When I was in school, Anti lock and fail safe brakes weren't that old either. I'll be 66 in 4 days and have been disabled for 22 years this past February. Stagnation is my middle name.

oh the FBI most likely knew everything they was doing and sit on it for a very long time until they was ready to bust you... untaxed fuel is way more common that you may think but the gov't usually don't come after you until they know you made a certain amt so that they can seize your money... can't hide or smuggle that amt of fuel without the gov't not knowing because the oil companies got the best of the best working for them and they would be the ones to find these operations and then force the gov't to go after ppl... down in the Florida area (i'm not going to say where) i knew a few guys who actually made aviation fuel and they got their raw supplies all the way from Venezuela (i never did buy anything) but they told me how things work.. you're right about everything else, you got to have a good chemist (a Walter White) but they didn't steal anything as business men sold them what they needed on the down low..

[@girthquake1413]

@@dunhillsupramk3 Yup, that's how intelligence rolls; they don't go after anyone until it makes economic sense to do so. I actually had a neighbor years back who made his own biodiesel for his Duramax back during the financial crash; in common midwestern style he had his 1000 gallon EPA containers of used oils and chemicals sitting outside, no biggie alongside his garage. Tons of neighbors complained that it looked like a meth lab and demanded the local Sheriff do something about it, only to get them explaining to the NIMBYs that there was no way government agencies would go after one guy even if he was doing something illegal because of how little economic impact he was having. Pretty sure he's still making it today too.

This reads like the navy seal copypasta

[@georgehuser4711]

Damn if I could use some sort of alternative. But those new diesels with high pressure systems will fall apart just by smelling this stuff lol

Thanks for the feedback.

You could probably run up to a 50% biodiesel mix in common rails if you didn't have to take the DPF into account. I wish more places offered bio anymore. Doing a 20% mix keeps the modern pumps alive longer and probably wont kill DPF's faster than normal.

[@davidellis279]

Get this mixture wrong on the high pressure common rail diesels and your in for some expensive repairs to the fuel injection system, the old type indirect injection engines are far more tolerant to fuel quality than the new engines. I’ve known people use old filtered engine oil diluted with Kerosene to make it thinner for use in winter when the temperature drops but again only in the old IDI engines.

[@CondoreComputing]

@@davidellis279 You deffinitly have to be careful, you need to use well processed bio for your mixture, especially on the CP4 designs though, the pumps will last way longer on at least a light bio mix. Most manufacturers have to rate the modern diesels for B20 now since that is mandated in some areas, so I'm fairly sure you can push a bit past the manufacturer recommendation with the headroom they usualy include. I wouldn't trust the random stuff that the neighbor made in his garage. The commercial blends have to be tested to make sure all the chemicals used for glycerin removal have been washed out.

[@Jv19979]

I thought new diesel can use b20

I( have gotten to the point where if I am thinking of something to do with ANYTHING mechanical, the first thing I do is go to your channel and type it in! Thank you AGAIN for a great video, you are a treasure.

[@ProjectFarm]

Thanks!

[@tobyquezambra4969]

I love the tests, Good job. What’s the result if you add new oil to old if you have a slight leak or blow by? Does it contaminate the new oil as soon as it mixes with the old?

[@steveklassen696]

All the political stuff these days really gets tiring. I really appreciate how you stay out of it all, and just create awesome educational and useful content. Keep up the awesome work!

[@ProjectFarm]

Thank you very much!

What do you mean by "political stuff?"

[@steveklassen696]

@@wiredforstereo oh I mean that so many things out there are all political. I love that this channel is good clean useful information. It’s a huge breath of fresh air.

[@javig4817]

I'm sorry but everything is political even if we don't like it. Because politics have direct impact in your life. The most tested cars for biodiesel and oils are french, cause the taxes and prices for fuel were increased and lots of people started to try. For example

[@wiredforstereo]

@@steveklassen696 You didn't explain what you meant by "political stuff" at all. What do you mean by "political stuff?" What political stuff are you talking about?

You should do a comparison of windshield crack/chip repair! Like which ones actually hold and prevent additional cracking, visibility of cracks afterwards, and why
