Is Non-Ethanol Gasoline Really Better? See the PROOF!

Petroleum-based gasoline that does not contain ethanol will still succumb to oxidation and volatile compound evaporation in a sealed container or tank, but these processes usually occur more slowly in pure gasoline. Expect non-ethanol gas to last at least 6 months if it's properly stored.Sep 9, 2022

Do it with the E85!!

it's a bad thing!

Ethanol's biggest problem is it's derivative acetic acid, that corrodes brass carburettor jets. Zinc in the brass oxidises to white zinc oxide, which has to be removed manually by stripping down the carburettor to get to the jets. Ethanol actually oxides over time, if left to stand in a vehicle, into acetic acid. This acetic acid will also rust out steel tanks and fuel lines, causing the fuel filter to become blocked, as well as the jets.

Love it thanks

I bought a Westinghouse 3200 pressure washer. It is suggested i use non ethanol gas. Not sure if this is necessary. Some reviews say it runs better. And can i get non ethanol anywhere

If its so bad, why did professional racing switch to E85+ ethanol fuel almost a quarter of a century ago?

Can't wait to see your future testing.

I just purchased 4 Cycle Ethanol-Free Fuel 2.1 Gal from Home Depot. For my Harbor Freight Predator 3500 generator. Do you still have to use a fuel stabilizer?

Hey Todd, What ever happened to the follow up regarding Ethanol's effects on the plastic and rubber engine components? I hope that's still in the pipeline for someday.

Physics, chemistry, mechanics, all in one channel. What more could a guy ask for.

Can dry gas destroy my new maf sensor?

The moral of this story is that you should use the fuel recommended by the manufacturer. My car was designed to run on 10% blended fuel and I have used 91 and 98 octane fuel with no marked difference in fuel economy. Engines that are designed and recommended to run on ethanol blended fuel have the appropriate fuel lines installed. It is true that over time the ethanol will seperate if the fuel is left for any length of time if it is exposed to the atmosphere I have a sealed glass container of ethanol blended fuel that I have kept for over 12 months and has no sign of separation. There was a study conducted by the US military in that they analysed the wear characteristics of various fuels on engines with methanol being the fuel that caused more damage. Ethanol was on a par with unadulterated fuel.

We could be feeding living organisms with the corn that we put in our fuel. I know farmers won't like this sentiment. I think it's ashame to waste food when we have an abundant source of crude under our feet for many years to come. I am lucky. Where I am at I can get anywhere from 87 to 93 Octane of REAL GAS. 87 octane is .60 per gallon more. I run that in my 99 Nissan Frontier. Owners manual says to stay away from ethanol/methanol if it can be avoided. Runs like a top. 2nd owner with 59k on the odometer. Original owner burned straight fuel too.

Of course! 100% EtOH is 30% less energy dense than 100% gasoline. But the risk of water condensation in cold climate and with fuels stored longer (ie in small engine home owner scenarios) is higher up here in the northern midwest and has caused EtOH spiked fuels to lead to stalling and starting issues over non EtOH spiked petro fuels in my experience thus negating the oxygenation benefit of EtOH spiked fuels. So in my car with high fuel usage rate....I go with low octane, regular EtOH spiked fuels at the pump..... but with my snow throwers and other small engines that sit a long time between runs.....I run 100% petro.

👍👍😎

All i know is my Honda mower will not run properly on pump gas. It wont idle and the revs pulse. If i run it on Alkylate fuel, no issue

Garage54 did tests with E10 and E75 ethanol petrlium, and E75 is cleaner (because i is 75% ethanol) but it is not fuel efficient.

They tested it in Thailand.

What about 20% ethanol

RAL is right i have never had so many spring time carb issues try testing two motors sitting over winter & see witch starts & stays running . you will find the ethanol motor will be the problem child ( full of white oxidization) .that is the test that shows the problem with ethanol gas.

Using ethanol free gasoline has improved the fuel economy of my 2022 Power Wagon by 8% and my truck feels like it has more power.

Project farm should test whether two-stroke oil really adds compression & power to a 4 stroke!!

Ethanol is good for giving you higher octane rating!!

well on the news when people started buying 16 percent ethanol they found out that it clogged fuel pumps and if my imagination or not i find engine runs smoother on non ethanol although most time i use with- so idk

So, I understand the results with a small engine and similar carbon deposits with ethanol and non-ethanol fuel. What are the results with the same comparison with "direct" fuel injections engines in newer automobiles?

Possible topic: E85 vs fuel with 10% ethanol vs fuel with no ethanol. And/or advantages or disadvantages of E85.
As always and as everyone says, great content! Thank you!

I have a 25 year old Tecumseh 2hp Craftsman lawnmower, a carb dirt bike, a carb generator. I have zero carb problems because I only run Non-ethanol 91 octane and full synthetic oil.

I don't understand why these small engines get screwed up so quickly with normal gas.

We have an old Saturn which we sometimes don't use for well over a month. A lawnmower would have to go to the shop to get started if the gas was left. But the Saturn starts. The problem isn't the gas. It's the motors and carbs. Shame on them.

Please do an e85 test on an older vehicle so we can see what it will do to the lines. I’ve replaced so much stuff on my car I think I just need the return, the 1ft double banjo line and injectors. The main is steel braided

I DONT NEED YOU TO TELL ME ABOUT HOW BAD ETHANOL IS FOR CARS. EVERYONE SHOULD KNOW HOW BAD IT IS. SO GOOD FOR YOU TO HELP TELL THEM BUT I HAVE KNOWN THIS FOR YEARS. WHEN THIS GOVERNMENT GETS INVOLVED WITH ANYTHING ITS BAD FOR EVERYONE. WE NEED WAY LESS GOVERNMENT IN EVERYTHING.

Ethanol added to fuel lowers the energy burnt per litre. Its cheaper here in NZ than proper fuel (10%) but others have said you wont get the same mileage with cars. Ok the worse stuff: phase separation, Issues with composites (fuel tanks), issues with metals in older vehicles (fuel pumps and carbs ) I avoid it like the plaque. Even a large automobile watch group here said to avoid it unl;ess they make it a lot cheaper.

Thank GWB for pandering to corn ag mega corps, ruining education with NCLBA, and starting a war on the rumors of WMDs so Cheney could make money. And that's why there's corn alcohol fuel in your car and mower because it's the law.

If you do not like ETHANOL buy HIGH-GRADE fuel without it! Some gas stations offer NO ethanol fuels.. Most cars and machines are built to take it though nowadays..

Excellent testing. Always enjoy your work. I'm 68 and raced motocross and snowmobiles till I smartened up. Lol. I never use regular with ethanol in anything especially small engines. I've seen a lot of damage to aluminum, steel gas tanks, seals and gaskets.

ethanol in gas is all political

Ethanol is said to have a cooling effect, but that also presupposes that more fuel is pumped in, so the right fuel, the amount of oxygen, the mixture

Was the gasoline generator made for ethanol like optimized compression etc

Now there are products that are said to reduce the disadvantages of E85, such as the product from Redlight

If you mix the ethanol yourself into the petrol, you will, however, get a higher octane value and can increase the compression and change the timing if you are someone who is involved in motor sports or interested in performance. Pure ethanol has well over 100 octane and contains more oxygen. so if petrol companies without added more ethanol with zero octane content are just as high, then they would probably have done it by reducing some other octane-increasing chemical? Or in another way

I put sta-bil in my gas and never had a problem even after months of setting. Starts right up every time.

Does ethanol-free fuel have additives like the regular fuels?

Well. Alcohol is a racing fuel quality. Far superior to gasoline in almost every way except perhaps energy content when comparing gasoline-compression ratio engines non-optimized for alcohol fuels such as methanol and ethanol. Saying its 'worse' just because some (any particular) engine isn't designed for alcohol and it melts some component isn't actually a strike against alcohol.

i run ethanol free in all my tools, its a completely different ball game, carbs are clean, starts every time, only use ethanol free in tools and boats if you can.

Ethanol sucks. Bad solution to a nonexistent problem.

This debate is silly. Henry Ford started producing Model T's in 1908 that could run on an ethanol - gasoline blend after the Federal Government ended the $2 per gallon tax that was levied to help fund the US Civil War. Refiners used ethanol to raise octane levels since then with little being used from the late 40's to 1974 due to the abundance of cheap lead compounds. During WW2 civilian gasoline sold in the US contained from 10% to 65% ethanol so more gasoline and lead compounds was available for the military. I never heard any adults that drove back then complain about alcohol in gasoline screwingv up fuels, carburetors and metals. European countries continued to add ethanol to gasoline after the war. Great Britain sold a 'Cleveland Blend' until 1968. The US started using ethanol again to stretch gasoline stocks after the '73 Oil Embargo then to raise octane levels in unleaded gas. I was driving old trucks and cars back then that got the carburetor rebuilt and all new fuel lines due to rubber hardening and cracking. Drove those using the ethanol blend without having any problems. Maintained my powered lawn and construction equipment over the years using the standard rubber fuel lines sold at the auto parts stores. Those held up just fine so I assume they were producing alcohol resistant rubber fuel lines since the 1920's.

Don't know, don't have to care. Local gas depot that supplies the gas stations in this region have tanks on the water line. That is, their tanks extend below the ocean and their fuel just float on top of the ocean.
That means they cannot receive any ethanol based fuel, period.

If it has a carburetor I stick to non-ethanol. Ethanol was introduced to the market after fuel injection was dominant. A lot of what started this is companies like Honda refusing to warranty engines that have ethanol in them.

This is a pretty great way to remove the water. Thanks

Thanks!

ethanol issue is electrical and magnetical
