Will ethanol damage your car's engine? Is E10, E15, or E85 bad for you car? Can your car handle using ethanol/gasoline blends? This video aims to demystify the effects of alcohol fuels on engine wear, looking at Ethanol, Methanol, Unleaded Gasoline, and alcohol fuel blends.
A study was conducted published in SAE which was supported by the US DOE and US Army, which looked at various fuels and their effects on engine internals, such as the cylinder liner, piston rings, cam lobes and cam followers, and valve guides. They also looked at engine oil wear metal content, as well as sludge, varnish, and deposit formation in various engine locations. The results indicate the various effects of alcohol fuels on an engine.

A lot of folks seem to be focusing on the fact that it's a 20 hour test, rather than the results. Yet at 20 hours it shows significant differences amongst the results. Also, 20 hours at a high load is much more pressure and stress on an engine than what you do commuting, which is nearly constantly at a very low load. This is an accelerated test as far as wear is concerned. If there are discernible differences at 20 hours, you can certainly learn from the study. While many KZbin channels simply offer "word of mouth" advice, that's all too often received well, I find it surprising so many are so concerned with a peer reviewed, with controlled variables, published article in what is perhaps the world's most renown journal of automotive engineering. Skepticism is a good thing, we should always question things. This means also not drawing conclusions that the study does not state. It does not, however, mean that the study is meaningless simply because you perceive 20 hours to be a short duration. It's quite common in the industry to run accelerated benchmark tests in order to predict long term reliability. If you're putting out new engines every couple years, you simply don't have the time to run those engines (and all of the individual components involved) to 200,000 miles to see how well they do, so instead you use harsh, accelerated tests to predict future reliability. Anyways, rant over haha, I hope everyone's having a wonderful day!

The corrosive effects of Ethanol occur over time, both electrical and chemical wear, this test didn't take into account the effect of the increased amount of water in Ethanol Blends in the real world, or to two stroke motors (really the worst) or state (at least in your video ) which materials the motor was made from (cast Iron Block or aluminum?) so many variables to state conclusively that its just so, when its just not. Yes, in the right conditions, ethanol is both a viable and cleaner burning fuel than Gasoline. That however doesn't take into account the amount of fossil fuels used to grow, harvest, transport, and process the corn into Ethanol. It's a fuel, but don't confuse it with being a "Green" energy alternative.

What you call "word of mouth" I call "urban myths". I sometimes think Engineers like ourselves are wasting our breath (so to speak) trying to educate with FACTS. The biggest thing wrong with the internet of things is that it's made every numbskull into an expert. The most common one is that premium fuel isn't "worth it" (whatever 'it' is?) because all petrol is the same. And how do we know this? Because Bob is a tanker driver and has 'seen' the tankers always being filled from the same outlets at the refinary ..... YOU know the rest of the song .... Keep the faith Jason

As a mechanic during my college years, the concern about ethanol was not what it did to an engine but, what it did to the inside of the rubber fuel lines, that did the most damage to the engine. Ethanol will degrade rubber and, as the rubber begins to disintegrate inside the rubber fuel lines it turns into a gel that comes up the injection or carburetion on older cars. I never saw damage done by ethanol from a mechanical standpoint.But, have seen the damage it’s done through fuel line degradation. Thank you

My 1993 Opel is rated to be allowed to use E10, but after using it for two years I can tell that my mono-point injector or its rubber sealing rings started failing slowly and leaking fuel, until the point where the engine would be flooded on cold starts and not run until waiting the petrol to vaporize. Finally last December it completely died and the petrol finally made it through the piston rings to the oil sump, where it got in the oil filter and so it starved the engine of oil. End of life, piston rods seized. Motor oil smelling strongly like gasoline. Would this never have happened on E95? Who knows, but it's my experience at least.

Thanks for this awesome information my Brazilian brother. I’m living in the USA and always wondered why they won’t try that Brazilian Technology here as well…, But the assumption I have may sound more like a Conspiracy theory though, which is “The Big Oil Industry of America”, forbid such technology to ever start here and deeply take away their profits. Also i believe Brazil has sugar cane fields that can support your home made fuel, but I’ve heard here in the USA, they don’t have that option, and would have to buy sugar cane from Cuba, but the embargo into Cuba, forbids that. So I don’t believe America will ever use the Brazilian ethanol fuel system…, unfortunately.

“Ethanol has less energy content”… @ 9:20.

The push for E10 was absolutely not a practical one, it was not a “green” initiative, it was purely a way to stimulate the agriculture economy.

The fuel system damage of ethanol is a big issue in the motorcycle and power boating sectors. The tendency for seasonal use means a LOT of older engines out there and the long fuel term storage issues are more problematic. Would love to see any research available on additives that deal with these issues. Perhaps the simplest and ideal option would be to keep Ethanol out of PREMIUM gasoline all together.

Most of this “ethanol only” cars still alive 30 years later.

The problem with ethanol doesnt lie in the engine block.... it lies with the fuel system and any rubber/man made material it comes into contact with. Additionally, I dont think we should be using fossil fuels to process millions of bushels of corn into inefficient fuel...... One would be better off feeding the rest of the world with the corn surplus and just go with gasoline. The same goes for using electric vehicles, there is absolutely no point in using an EV that get's it's power from a grid that is, for the most part, powered by coal. You are outsourcing pollution, and you are outsourcing it to a more inefficient source than you would if it were from gasoline. You also then have to factor in transmission losses.... conversion losses from heat to mechanical to electrical..... losses in charging... losses in converting all of that back into electricity and mechanical energy..... Its just a waste of time, never mind the poor chinese slaves who mine all that explosive lithium for you with polluting machinery who then ship it on cargo ships that run on diesel.

Also, LPG is already about the same real price as petrol. The difference in the price you pay at the pump is pretty much entirely tax. The only reason petrol is so cheap in the US is precisely because it doesn't pay that extra tax.

I really appreciate the research that went into your presentation. Thank you. I rebuilt a 2010 Chevy 2.2 L Ecotec engine with VVT (Variable Valve Timing) last year. It failed due to low compression and, after disassembly , it 0 PSI compression was caused by a build up of material on the intake valve stems exactly where the injectors direct their spray. The engine has 225,000 km on it and everything else was well within spec except the timing chain and its associated parts. The failure was obviously due to the E10 fuel but with that mileage, it is pretty hard to call it a fail. I am not a mechanic but a retired physicist so my point of view may be a little different. I do, however, see a large fuel related failure due to ethanol in small engines, lawn mowers and chain saws, where the carburation components fail completely. This is most likely due to the corrosive nature of the ethanol. In the case of small engines, I would strongly recommend the use of non-alcohol fuel, or, at the very least, regular grade fuel that has less alcohol.

It's not the water that's the problem. Slight water content is actually a fantastic thing for your engine. Water is incompressible, but when it's very little, it steams off, removing carbon deposits. The real issue is marine stuff is very often sold at a price that is significantly higher than automotive parts, but they use the old rubbers to save the manufacturer money (and guarantee return business) and many marine applications use aluminum fuel tanks for weight savings. These are the issues. Crap parts, incompatible chemistries with the fuel tank.

If the Ethyl alcohol in the petroleum blend, "absorbs" water from humid air, then that absorbed water will burn as it becomes tempered alcohol. Like 80proof booze vs 60proof. Both still will get you there, but 60proof or "Scotch and Water" will take you longer than straight Scotch at the same volume. I used to have a lot more problems on Mobile Bay with a lawnmower and pure gasoline. Mow and put it up on 1/4 tank, humidity gets in, condenses, gasoline isolates it to a bottom layer, damned thing won't start next week. So Ethanol that has not already been saturated with water, will mix with humidity better than gasoline. If your tank is vented and gravity fed (small motorcycle or mower) then the rule is keep it full till end of season then store it completely dry. If you have a petcock then it is easy to drain through the reserve setting. If humidity gets into your tank above the fill line, it will condense when the temperature drops. Thus you notice water in your fuel in the hot day, cool nights months. Physics and chemistry, vs anecdotal guessing.

It is true that it's fine for cars. You did mention the main issue, but kind of brushed by it. Ethanol is very bad for small engines. It's fine to run them with an ethanol blend, but due to the nature of how many small engines are used, they often sit for a decent amount of time without use. The absorption of water and separation is pretty harmful for small engines. I have never met a company that chooses to use ethanol mix gas for chainsaws and similar equipment. Gas without is often 30% more expensive, but it's judged that the reduced maintenance issues from buying ethanol free makes that cost worth it (buying more new saws, and putting more repairs into already owned saws adds up). The only companies I am aware of that use ethanol mix are extremely unprofessional in other regards as well I ain't no scientist, but this is the general industry consensus. It's more economical to buy premium gasoline for small engines, vs buying ethanol mix and spending more on repairs and replacement.

Gasoline mixtures go bad. Gas caps must vent or fuel cannot flow into the carburetor, and as everyone should know, oxidation (exposed to oxygen) destroys everything. This is why humans can't breathe straight oxygen for very long, as it literally destroys the lungs given enough time. There are stabilizers to prevent this from happening so fast, but ideally, you want to burn that fuel within a week and run the engine until the tank and carburetor bowl is dry. Hope this helps!

What I'd really like is an environment impact vid of E10, because seemingly even governments can't agree on whether the real world impact of E10 is lower or higher pollution and "bad" emissions - some say that because the E10 emits less CO2 total emissions are cleaner, others that that's offset by the lower fuel economy and people seem to quote different examples of how switching to ethanol fuels in a region either improved or worsened emissions there. In fact there's so much politics behind it it's pretty hard to google a definitive.

Canadian Mohawk 90 grade with ethanol kept my spark plugs way cleaner in my old oil burner 390 Ford wagon in which I was running 20/50 oil. I changed the plugs often and the difference was astounding. A little bit of ethanol definitely eats cylinder deposits.

I'm surprised it's not brought up more but a notable advantage of the ethanol blend is that it lowers the freezing point of the water that gets mixed up in the fuel (believe me, it's in there) so it helps make sure you don't freeze your fuel lines in the winter (cold climate specific advantage). Winter fuel additives used to be a thing in Canada and I don't even see them sold in gas stations anymore now that E10 is the norm.

Very informative, this! I find it quite interesting that ethanol does not cause any noticeably adverse effects on the internals of a car engine, and this is from the established research of 1981. I remember a lot of scare-stories involving gasohol back in the day, and I was expecting to see the same thing with the mandatory reinstatement of gasohol. But it is good to know that gasohol will not actually cause any noticeable damage to an engine's innards (well, unless the -hol is METHanol, that is). Of course, then that begs the questions about overall energy efficiency and any adverse effects on the fuel-delivery systems, and this video does confirm those concerns: Ethanol does not produce the same BTUs gasoline does (ergo, from an energy-output perspective, less efficient as a fuel), and its alcohol nature can corrode carburetors. So, bottom line for me is, I am actually doing my car (which is as old as I am) a service overall by identifying and utilizing pure-gasoline outlets...but in a pinch, using occasional gasohol will not strand me.

I'm a small engine technician (had many engines aparts over the years) I have noticed engines run on ethanol blend fuel have thicker build up of carbon than engines that haven't been run on ethanol blend fuel. Carbon is sticking to the piston crowns badly at least on the air cooled carberated engines witch can causing issues overtime. I have older flat head engine maintenance manuals saying to pull the head of and clean out the carbon build up. (around every 200 hours) That being said nobody does that and the prossess is made more difficult with introduction of OHV heads so I suggest running a cleaner threw small engines (around 200 hours) to prevent excessive carbon build up😉

Here in Brazil we have 3 fuel options: 92% hydrated ethanol, gasoline with 27% ethanol and premium gasoline with 25% ethanol. Most of the flex fuel cars run with more HP when running with full ethanol (some with 10% more power) and the price is 60% to 70% of the basic gasoline. But the car with ethanol does something about 75% of the mpg then running with gasoline.

E20 in the US was tested and shown to decrease MPG by 7.7%. I alternate E10 and fullgas on my 2013 Accord all the time and the noramlly don't see a difference of 1 mpg, and I normally get 39-41 on either. (yesterday was 42.5). Ethanol has 67% the energy content of gasoline. If 10% of your tank is ethanol, you'd get the 90% of energy of the full gas portion and the 6.7% in the 10% ethanol, total 96% or so total energy... that's about a 3-4% drop in total energy, and at 40 mpg, a drop of 1 mpg would be 2.5%, so it's splitting hairs. I go through almost a full 17 gallon tank every 8 days or so... mostly highway miles in suburban setting in UT county, Utah - that's where Provo is, just south of Salt Lake City...

I’m no mechanical engineer, but usually cars running high ethanol content tend to be performance tuned to their fuel. Majority of them are fitted with an oil management system like a catch can set up.. so moisture would be separated before returning back in the engine via intake.

The US Navy once said a a ethanol gasoline blend was ideal ,then recanted when the separation problems came up. Way before 1980 . But a 20 hour test is not realistic. Take a 1,000 hour test with periods of cooldow to full temperature and load and get a real indication of wear in the bottom end as well as the top cylinder area. CAT says Moo.

I once tried to run my old car on E85. The user manual said the engine was fully compatible with ethanol mixes up to E85. Ran some time without any problems, but after some time it started burning oil. I had the head removed, and the ethanol had eaten through all valve oil seals. All 8 of them. So the engine was running mostly on oil at that time. Had to have it rebuilt. But hey, I passed the first emissions test with flying colors!
