Does Fuel Stabilizer Prevent Ethanol Damage? Let's find out!

[@ProjectFarm]

Thanks for requesting this one. I have another video on fuel stabilizer on the way but it'll be a couple of more months before they fuel has reached 12 months. Here's a link to Lucas Oil Safeguard Ethanol Fuel Conditioner: amzn.to/2YoesHa

[@bobthompson4319]

It seems like the non ethanol fuel will run but the engine needs to be hot already. Like the spark plug and exhaust valve need to be at operating temperature? Maybe? Or at least very hot. Because ether burns very hot and makes engines hot "warming them up" and allowing them to stay running. But just because they run i have no doubt that the work that the engine will be abke to do with that poor fuel will definitely be less.

[@SeaPro360]

Great videos. Would you do one with marine Stabil (blue) and E-10? I just don't know of anyone who uses Lucas. Keep up the good work.

[@heyitsdrew]

does the stabilizer go bad? that would be something to test, like what if after a couple months you would add some fresh stabilizer or a little fresh fuel? on a side note: I'm not a chemist but what if whatever attracts water to ethanol is taken out of the equation? such as a water-like compound which replaces it in ethanol so that it can burn instead

[@mjktrash]

I was looking for an "Old" fuel video, good thinking!

[@Fixin2Ride-Official-]

I bet you could get a good idea on how the fuels affect the rubber components by a pressure needed for compression of the rubber to a certain distance. So for example the new hose fuel hose would be the control reading and would give a reading of say 1.5psi needed to make the inside of the hose touch each other when pinched off. Something of that sort. With other stuff you could pinch it and get a reading, and then measure the distance pinched for the reading you got and make a shim of that thickness of metal or use a certain thickness metal from the beginning. This would give you the most accurate comparison between the rubber products. You can contact me further if you want to do this but I didn't completely explain myself well enough. ;o) I really like your videos. God Bless! Andrew C.

[@gtg289b]

Hey! I'm an engine design engineer that's designed fuel systems and engines from big diesels to small 2-strokes. You mentioned not having a way to measure the effect on the rubber components. The 2 biggest problems with elastomers exposed to ethanol are swell and embrittlement. You can measure swelling by measuring dimensions (or volume) before and after, or you can measure mass change (be sure to dry the sample out before weighing). For embrittlement the best way to measure is measuring durometer. Without having a durometer tester you can use a fixed load to press a dull point (like a punch) into the elastomer and measure how deep it sinks into the sample under this load. I used to design consumer-grade 2-stroke outdoor power equipment. I'd always tell people if you use E10 the degradation of elastomers (fuel lines, carburetor diaphragms, etc...) will kill your product long before the engine dies. Really enjoyed the video.

Amazing. You've completely validated what I've been doing with my lawnmower and snowblower for the last 13 years. Every spring I run my snowblower out of gasoline, and put it in storage. Then I make my twice yearly trip to the "special" gas station to buy non-oxygenated (non-ethanol) gasoline. I then add sta-bil to the gasoline. In the late fall, I perform the same procedure on the lawnmower, and replace the gasoline again and get the snowblower to start. In 13 years I've had 0 problems with both small engines, and they both start right up with one or two pulls. I was more than a little shocked to see how much gunk was in the ethanol + aluminum containers, and absolutely zero in the non-ethanol ones. I'm tickled to see that the practice I heard about years ago stands up extremely well to experiment!

[@ProjectFarm]

Thanks!

[@Weezulguy]

How does what he posted validate the need for stabilizer at all? My conclusion is that it doesn't do anything at all based on those last two runs... I definitely agree that running everything dry is the best approach, I let them sit with the caps off with a rag over it so they can evaporate anything else out as well.

[@scarhart53]

The best way is to use only no ethanol fuel at all times, and leave the tank full all winter to keep moisture out. You can run the carb dry if you want, but with E0 gas, it doesn't really make any difference.

[@brentiverson1654]

You don’t need to mix stabil with non ethanol. Stabil needs ethanol spray to bind to if it doesn’t have any it’s pointless

[@stevesether]

@@brentiverson1654 Stabil pre-dates putting ethanol in fuel, so no, it's not just for ethanol fuel. Gasoline also degrades itself over time, and causes problems for engines. Still, it'd be interesting to see what problems other than water contamination corrosion sta-bil solves in non-ethanol fuel.

Pretty interesting video, confirming many of my thoughts on ethanol. I do small engine repair and have seen carburetors become damaged beyond repair after a machine sits for a year. When I was a young man (circa 1972-1978) I mowed the grass at my parents house. I used a Toro Reel Mower, I never had a problem firing it up and it was used pretty regularly. Ethanol had not come into the picture yet. From time to time over the years after I moved out I went and mowed for my mom. She hired gardeners and they never used that old mower. Every time I went and mowed for my mom that old machine fired right up. There were several times I didn't mow her grass with that machine for well over a year, even 2 or 3 years and it always fired right up.

[@ProjectFarm]

Thanks for sharing.

[@NoFeeArea]

I think the stuff is garbage. I leave gas sitting in the mower or snowblower until the next season and Never had an issue with carburetors or starting up after choking and a couple pulls. The fuel evaporates out of the carb anyways in probably less than a day and the tanks are sealed. If it were a big issue the carbs would be junk after one season or two of using because when you are done each snowstorm or mowing there is always gas sitting in the carburetor until the following mow time or snow. This isn't the case. I call bunk on these additives.

[@charles09361]

@@NoFeeArea Interesting view.. Allow me to rebut.. First point.. Older stuff Equipment), is way more forgiving than newer stuff. Emission compliance mandates force manufacturers to tune lean.. That means smaller orifices in the carbs, that plug up way easier than twenty years ago. Second point... "Fuel evaporates out of the carbs".. Well that only happens if there is a fuel shut off.. and you actually use it! Otherwise, on a lawnmower, or snowblower, the fuel tank will gravity feed against the needle valve in the float bowl, and keep the carb filled with fuel. Fuel evaporation, is exactly just that. The "fuel" evaporates, and leaves behind varnish. The only way to avoid that, is to shut off the fuel to the carb, and run it dry. Third point... " and the tanks are sealed". Ummm .. On a 2 stroke, they are, on a 4 stroke, they're vented. Basically, if a carb has a float, on a small engine, it's vented. If there's no float bowl, it's sealed. That's why you can run a weed eater or chainsaw upside down.. It has a fuel diaphragm as a fuel pump, and it's run by compression pulses from the crankcase. As a carb that has a gravity feed fuel system, it has to have a fuel cap vent to allow the fuel to flow. Take the un-vented fuel tank cap off your 2 stroke weed eater, put it on your lawnmower and see how long it runs before it starves for fuel and dies, because there's no way for air to get into the fuel tank, creating a vacuum. So, which is it? " The fuel evaporates out of the carb in less than a day", or, " there is always gas gas sitting in the carburettor until the following mow time or snow." Ya can't have it both ways. If you can leave untreated Ethanol pump gas in your snowblower from one season till the next, and it starts in a couple of pulls... You're way luckier than the rest of us..

[@NoFeeArea]

@@charles09361 Allow me to retort. Ihave never used any fuel treatment. After a few pulls (mower in the spring) or (blower in fall) everything starts right up and after 30 seconds runs great. It's overkill and a waste of money IMO. Not for me.

Your comprehensive testing is FANTASTIC and showing proof of the ill effects of Ethanol in fuel in limited use engines and fuel systems.

[@PAD32]

Long answer : It's not a real world test, but a worst case scenario where the fuel has been intentionnaly contaminated with water. In real world, you will not get as much water if your fuel. Also, carburator are more prone to damage, but they are not compatible with ethanol. Injection systems (100% of modern vehicules) are much less exposed to corrosion because there is no air (and therefore no water) in the fuel lines and injectors. Also, all modern fuel tanks are in plastic or have a protection layer in it, so it will not corrode either. I'm not saying there is no corrosion at all, but it's certainly not something to worry about, unless you store your vehicule for a long period. Short answer : in real world, with a modern vehicule, ethanol based fuel will not cause significative corrosion (except maybe if you store it for a long time).

[@PAD32]

@mark robertson Wow, you totally changed my mind, thanks for opening my eyes ! Joke aside, just saying "disagree" brings nothing to the conversation ;-) . If you have factual counter argument, I would be happy to hear it

[@PAD32]

​@Blind Squid I know ethanol is hygroscopic, I'm just saying that what we see in those tests is an extreme scenario. You can find similar tests where there was no intentional contamination, and there was no corrosion at all. If the ethanol damaged your vehicle to the point of it running bad, it would still be the case after you stopped using it. What kind of degradation did you see ? I don't know about other countries, but in France, there is no ethanol free gasoline. The "best" you can get contains up to 5% ethanol, and that's true since at least a decade. If it was an issue, there would be a lot of cars mysteriously breaking down since the apparition of biofuel. But that's not happening. You don't go from perfectly fine at 5% ethanol, to catastrophic failure at 10%. So just don't worry about it... I use only E85 since 1 year (with a modded car), and I have no issue at all. About exhaust temperature, injector saturation etc, I read a lot of bullshit, so I tested everything myself, and everything works just the same as with gasoline, but that's not the topic. I did a lot of research a year ago, before converting my car, and I couldn't find any reliable evidence that ethanol caused damage to any modern car on the internet. Overall, there is let's say no negative feedback. And yet people like to complain... People saying it damage engines never has proofs. They just relay what they found on random crappy auto blog or website. BUT I agree that it MAY cause damages to some parts in direct contact with the fuel in the long run, like fuel pump or injectors. I'm not even sure about that, as those parts are designed to work with ethanol in every modern car. But honestly, I save the equivalent of 1000$ each year just in fuel. So if I have to replace a fuel pump a little sooner than expected, I just don't care...

My 50hp, Mercury outboard, 4 stroke was originally run on 87 with ethanol right from the pump by the original owner. He had not changed the fuel filter for 3 years. When I changed the fuel filter, there was a considerable amount of yellowish, very fine, almost pumice like material in the fuel filter. I have run non-alcohol, 92 for the past 4 years and the fuel filter looks like new every season. That’s proof enough for me. I use nothing but non-alcohol 92 in all small engines, outboards, etc. Thanks for your excellent video!

Thank you for giving a good visual on how ethanol affects older fuel systems. All my cars are 40+ years old and carbureted, so I use ethanal-free gas from the station right down the road from my house. Glad to know I'm not throwing my money away by paying the small premium for the ethanol-free stuff. In the past, I did have some carbureted cars that I ran on the 10% ethanol gas, and I did start to experience some problems after a few years of that. The cars still ran well enough that I could keep them going down the road (with some babying at times), but there were clearly issues. Wasn't sure if it was just age, or if the fuel was the problem. Based on this, I'd say the E10 fuel was most likely a big contributor to my issues.

[@martinschulz9381]

My experience. I used ethanol gas in my small engines for years before I learned that non ethanol fuel was available in my area.

This just confirms what I've believed and done for years, close the fuel valve run it dry, and before it stalls pull the choke to suck the bowl clean. No storage issues!

[@ProjectFarm]

Thank you

[@vincentrobinette1507]

That's exactly what I do with my snow blower after winter, and my lawn mower just before I put it away for the season, and my generators, everytime I use them. The problem with the generators is I never know when I'll need them next, so I run the carburetors dry after every use. I sometimes pause a few minutes, pull the choke, and try to start them again. More often than not, they actually try to start, then run out, before they come up to speed, as it gets the fumes out of the float bowl, and clears the idle and main circuits of the carburetor, so there is no fuel to evaporate and leave gum or varnish, and especially, to avoid corrosion, and galvanization. You have a steel float bowl, and brass jets, and emulsion tubes, in an aluminum housing. Any conductive or electrolytic liquid(that includes alcohol) invites galvanization, which destroys carburetors, because of dissimilar metals. That's above and beyond the corrosion shown in the video, where there was just the aluminum housing samples used in this video.

[@OlivierCaron]

My generator will run for a good 2 minutes longer with the choke pulled, so that's a decent amount of gas that would be left in the line and carb. It's a good tip.

[@mikecheeze4312]

That's a good tip, thank you!

[@mooglemy3813]

@Eddie Coyle why, drain the float bowl and that works every time. Long term storage drain the fuel tank and carb. Make sure they're dry completely. No fuel in it store in the garage not a shed. Place a piece of heavy plastic like a freezer bag under the gas cap and lock it down, this stops venting as temp changes. 1 other point pumped fuel is good for 30 days after that it looses some of its volatility due to outgassing and or venting through the filler cap or the carb vent.. Not as big an issue on a car or closed circuit fuel system. Fuel in the rail will go several years before its lost it's volatility. There is no need for ethanol to be added to fuel. Must be Monsanto at work growing GMO corn and ensuring that they have an undisputed profit. Keeps the the price of corn up.

God knows how much longer the original still might've lasted as I not once ever ran it dry of fuel), and upon looking in the tank I didn't see a single speck of corrosion. I credit my near obsessive use of ethanol free fuel for this. Given the era the truck was manufactured, along with political reasons to do with corn subsidies pushed on American farmers, I refuse to use fuel containing any ethanol in my truck or any of my small engines.

Sir! Great video as always with well documented results. Interestingly, I flew in an aircraft ( DeHavilland DHC-3 "OTTER" ) which used a Pratt & Whitney R1340 9 cylinder radial engine. We were flying a scientific mission in the Canadian High Arctic. We used 14000 gallons of aviation 80/87 & 130 octane that had sat in drums for 20 odd years (since 1946 & we used it in 1971). We drew random samples from the drums (55 gal. US) & sent them to EXXON labs in Edmonton for evaluation. Exxon labs supplied us a report that was exhaustive in its range of tests, & that in essence said the fuel was "just fine" . The only irregularity it noted was a slightly elevated tendency to form "gum or varnish" compared to newly manufactured fuel. We flew hundreds of hours on the fuel with absolutely no problems of a fuel related nature. The drums were situated on an "esker" (sort of a big sand dune), laid on their sides since placed there in 46 when the photo survey of the Arctic was being undertaken. Considering that the automotive "pump gas" we buy today is premium "lamp oil" compared to the auto fuel 40 years ago, I believe that aviation gasoline is formulated to a strict standard that does not change year to year. I am not a chemist or chemical engineer & I stand to be corrected on this point. I thought you might find the info interesting. Another "gold medal" video my friend !

The venting of the fuel tank makes a big difference on how the fuel degrades. My first car (79 Dodge Omni) had a full tank of 10+ year old gasoline (likely ethanol free) and remarkably, the car started, ran, and didn't ping to my amazement. I ended up running that fuel for a couple hundred miles before I topped up the tank with fresh gas. With that said, it really is remarkable how corrosive the ethanol blends are to aluminum. I wonder how much better the marine Stabil product designed for ethanol would fare.

Most fuel stabilizers are sour diesel...aka Kerosene...aka English Paraffin and maybe a miniscule special ingredient. Kerosene coats surfaces providing a fluid layer protecting the metal and slows evaporation. You may have noticed how hard it is to get off a tool, table or your hand. So basically snake oil at $4 a half pint vs kerosene at 25c to 50c for the same cup worth. Oh that's a trick with many octane boosters too. They're either kerosene, alcohol or both... As both boost the octane number.

I always run engines dry on fuel on before storing them and have good results. when I was young my Granpa's friend said that he would mix a few ounces of transmission fluid with the last bit of fuel before running his fishing boat out of fuel to store it and that was the best thing to do to help prevent corrosion in the fuel system and the engine .

In fairness, most small engines really won’t be damaged by corrosion from ethanol. The fuel sits in the bowl that isn’t made of aluminum. And all the jets are typically brass or stainless. It definitely makes a mess of the carb if you leave it in, and you’ll have some work ahead of you to clean it up. Obviously if you have a carb full of fuel and flip the machine on its side or end and leave it for a couple years, that’s a completely different story and will end up with a carb looking like the one in this video.

Woods Tree Farm ethanol does have some advantages which are often left out by said curmudgeons, although I agree with them in principle and hate ethanol as a whole. Advantages include raising octane naturally (traditional fuel relied upon highly toxic aromatics) and decreased emissions. And the primary disadvantage of water corrosion is heavily minimized if it’s not stored long-term. But the major disadvantage is still immensely significant. Small decreases in emissions is pretty negligible if someone needs new carburetors, fuel lines and the like. Storage requires additives that apparently don’t work very well (see video). Possible decrease in fuel economy also limits its emissions benefits. And that’s just the ethanol itself, doesn’t even cover the production aspects.

If it is dirty or plugged it'll cause them to have a rough idle or surge at idle. I don't see any probs with mowers or power equipment as long as the ethanol is below 10%. But who knows how much ethanol is in fresh pumped gas. I'll agree that your gas mileage will drop on your vehicles and again I suspect there is more than 10 % ethanol in some pumped gas.

I have been adamant about and consistently stabilizing all my fuel for over 10 years now but I STILL had problems. This video really connected the dots for me with all my symptoms and improved my life. Now I happily drive over 100 miles (from south east CT) to the nearest station with ethanol free gasoline. Of course I will still stabilize; but at least the ethanol is gone! Thank you times 1 million!

You are welcome! Thanks for sharing!

[@borginator1493]

This is why I Always run non-ethanol in the mower, I just ran the mower out of fuel for winter storage. I've always had better luck doing it that way.

[@dbmail545]

We used to do that with all of our outboard motors at the end of the weekend.

Thank you!

came out pretty much as l would think it would, wonder how cam2 racing fuel does, thats what ive been using in my small engines that sit,

[@ProjectFarm]

Hi Mustie 1, Thanks for checking out the test and great recommendation on the Cam2 racing fuel!!

[@ARAR148]

hi, mustie1, I love watching your vids, I have a 1995 saturn coupe in storage, I run the car every 2-4 weeks, I plan to leave it in storage for at least 1 to 2 years, do you think sta-bil is any good, I just don't want any damage done to the car.

[@5thGenNativeTexan]

Not sure about Cam2, but the "canned" race fuel from Sunoco claims a shelf life of "in excess of three years".

[@buckykattguitar]

@@ARAR148 it does work excellent. I used to be a factory certified tech for BMW motorcycles USA and it's exactly what they want you to use.

[@donzack9667]

I’ve always used VP racing fuel in my outboards during storage. Run it on VP the last day to saturate the system. Start it up in spring and go fishing, never a problem. VP claims a shelf life of two years for racing gas. Pump gas 90 days.

Thank you very much! I'm heading over now to your channel now to see your video on Gallium!!

[@joeybomba8856]

Long as you going to leave that fuel sit in there for a extended amount of time it will be fine oh yes or no is just a little extra alcohol

[@bobshanery5152]

But it "helps" the environment. Why else did Gov spend tax dollars pushing this garbage? Gov is here to help right? I truly enjoy replacing engine parts I never had to before and lower fuel efficiency. But I'm sure ethanol will "help" the environment one day... Been what 15-20 years now? .. One day..

[@thatguyontheright1]

​@@bobshanery5152 I dunno why they pushed ethanol like that. What we used before as an octane boost, BTEX, is a carcinogen. Ethanol doesn't do that. But there is no perfect octane boosting chemical to throw into gas. the ideal solution would to make engines that can run on gas without lead, BTEX, and ethanol but that would be a very weak engine. Very low compression, no power, and people would still bitch. To minimize damage, just don't let gas sit in the engine or tank. I don't have a collector car or multiple cars I drive throughout the year, I only have one that I drive all year...so I've not had such issues in a vehicle. In small engines, when storing them I empty the gas out of the tank and carb bowl. And the efficiency thing, it's very minimal. It's not like you're losing 10mpg. I ran Ethanol fuel and non ethanol fuel and saw little advantage to either, still got 400 miles. What mattered more was the quality of the gas being used. If someone could come up with something better than Ethanol to boost octane in gas, that would be great. The old ways aren't always better, like the song says; the shit that used to work won't work now.

@@Catinthehackmatrix Gotta love the brainwash propaganda that people are fed by the govnt and those who have money interests in things. Its always money money money first. Its not just selling more fuel, its selling new cars, car parts and ruining other cars and gas engines. You lose a little fuel mileage with ethanol, it is harder on engines, and really doesnt help the environment like they say. It takes alot of energy to produce ethanol and there are many chemicals used in the process that have to be manufactured as well. Then add transporting it. All of which pollute some way or another. No ethanol or ethanol, rest assured the govnt has its tax on it as fuel is almost all tax at the pumps. Gas stations cant survive on just fuel sales, they have to have good in store sales. Only bigger fuel stations can buy in bulk most the time to get a small discount. 100% ehtanol would be cleaner burning but still polluting the same somewhere else.

I'll begin that test this week. Great suggestion!!

I would say non ethanol is best fuel stabilizer :-)

[@RustyOpel]

@@ProjectFarm Curious to that as well; I've been using Sta-Bil and my mowers start each spring, but SE North Carolina winters are short :) I suppose too there's a cost Vs. Benefit analysis if you are handy enough to change a carburetor every few years but even as simple as that is I'd rather not have to do so.

The best thing is that to remove the fuel from gas tank if the car is going to sit for a long time. Great video! Can you try to test diesel too?

So: ethanol and/or time are the disease, and stabilizer is a placebo. Good video. Thanks.

[@wildbill23c]

Stabilizer is a complete waste of time and money, just run the equipment out of fuel at the end of the season. Or use TruFuel.

[@Texassince1836]

If your fuel system is unsealed and sits for long periods of time ethanol isn't for you. Sealed automotive fuel systems that are regularly ran will see no detriment from running E10 fuels

[@alfredomarquez9777]

There is NO completely "sealed" system... When temperature goes down, air over the fuel will contract according to universal gas laws. If completely sealed, the fuel tank would collapse, therefore it is vented to break the partial vacuum... and everytime that vacuum is present, air humidity will enter the tank. So the gas cap is a one way valve, and fuel vapors are vented through an activated carbon canister, to be burned next time the engine is started... but that cap is not completely sealed against air ingress.

[@rogerbartels5223]

Another GREAT Video. You do a great job of replying to comments. Ethanol is prohibited in Aircraft Fuel Systems. Ethanol in fuel is a terrible idea and very bad for the environment. The ethanol will cause failures in the non metallic floats in some carburetors and will attack some types of seals. You never want your engine to stop while you are flying!!! I like your electric starter for your lawn mowers. Here is a suggestion for a test: Will auto gasoline stay "fresh" if it is in a totally sealed, pressurized container, such as in a propane bottle, filled completely full and then pressurized with dry nitrogen, to about 50 psi, then releasing about 5% of the gasoline to prevent over pressurization from expansion and then let the fuel stand for a year or more. Will the lack of oxygen and evaporation prevent the fuel from degrading? By preventing oxygenation of the fuel and the loss of the more volatile components of the fuel, it should last much longer. Fuel purchased in sealed barells does last longer. Have a great day!!!

[@ProjectFarm]

Thanks! Thanks for the suggestion.

[@wdog103]

Did you store all the jars with no lid? Seems like all the volatiles had evaporated away and left the heavy (less flammable) stuff behind. Very interesting video

[@ProjectFarm]

Thank you. Jars did have lids with 3 small holes and all jars were stored in a closed cabinet in the back of the shop. Testing approach was determined based upon advice from a fuel chemist to test how fuels are typically stored in a small engine....vented gas cap, air space in fuel tank and parts of fuel system, etc. Thanks again!!

[@wdog103]

[@firstielasty1162]

I worked at a motorcycle shop for years, and cleaned SO many carbs. Before the time of ethanol fuel, and after. No doubt, the ethanol does make more trouble. Many many customers were upset that this was needed, even after using stabilizer, so I have always been a skeptic. It is good to see that it does do something, but often not enough. I always drain carbs for winter. I'm an A&P, also, and often end up with 100LL avgas. It stores very well, far better than any car gas. All my power equipment runs on that for at least the last tank before winter. The 100 octane is unnecessary, but harmless. The high tetraethyl lead content (despite being called 100 low lead) could increase likelihood of plug fouling or valve deposits, but I have had no problems. I sometimes make weak premix for four strokes, to prevent valve & seat corrosion over winter. Never foul plugs from that, either.
