Where did you get that tester? I would like to have one myself. Kudos on the vid, that is very useful information.

Google eaa ethanol test kit and follow the link.

Oil companies are the monopoly. Ill give the farmer a cut rather than the Saudi's. Moonshiners ran their cars on it all the time, Thats what my great uncle did. Also E10 doesnt change gas mileage, Oil companies laugh anyway because they use it in place of MTBE,which is more expensive. And they get tax incentives that are suppose to lower cost of gas.. yeah right. I converted my car to soley use E85 and I get better mileage than using gasoline. So I use 85% less oil.

I am not aware of any state that has passed a mandatory gasoline law. I can buy a car that runs on anything I want. I am aware that four states have mandated that all gasoline sold in the state have 10% ethanol in it ... that is a monopoly last time I checked, you have no choice. Your claim that E85 gives better mileage than gasoline is total BS, I'll bet you burn water in you car too. E85 has only 75% of the energy of gas. Have you published your results? Do it, you will be famous.

Thanks for posting this. Ethanol sucks for sure, especially in small two stroke chainsaws or in boats. It takes 15 per cent more ethanol to acquire the same heat release properties as the same amount of gasoline.

@grumman581 the gunk problems occur if you dump a high concentration of ethanol into a tank that's been on gas for a year or two. another way to have gunk problems is to let the vehicle sit for an extended period of time without running the engine. the ethanol cleans your tank over time - even at 10 or 20%.

@grumman581 my understanding is that ethanol acts as a solvent. so it cleans out all the petroleum deposits left from gasoline. i have pretty good success by starting off with 10% ethanol in the tank. then 20 in the next 2 refills, then 30 in the next 3, and so on until all the deposits are gradually expelled.

@cameramonkey2 i think there is 5.7% in mot gas. but some stations go up to 10%.

@sdvten it's not always about better mileage. don't forget the extra octane and reduced emissions of ethanol. Gasoline has more power, but it runs more efficiently. And don't forget what it takes to get gasoline into a pump in the US. I have made ethanol at home... Can you say the same about gasoline?

[damonknutson]

We have tested over 50 vehicles with all types of mixtures. We found all cars run fine up to e25. some users reported improved mileage/performance with e30. but above e30, then mileage drops. Keep an open mind with ethanol. I have seen good things and bad things when using it. If people know what to expect and use it wisely - it can be a great substitute or additive to gasoline.

Thanks for posting the test. Ethanol absolutely sucks. No way in hell your going to get the same mileage with E10 or E85 as pure gas like that egyptian nutball posted. Pure Gas has stoich of 14.7:1, Pure Ethanol is 9:1 and E10 is 14.1:1. You are not going to get better mileage running a fuel that requires an enriched A/F ratio like ethanol tainted gas does. Luckily I can still get pure gas in my area in both 87 and 89.

@cameramonkey2 Actually, back then what they tried was mixing methanol with gasoline, not ethanol. I'm not sure exactly why they stopped doing it. It was during the gas crisis of 1973, IIRC. Before the ethanol gasoline contamination, they used MTBE. Both are to oxygenate the fuel for emissions. MTBE is allowed in fuel used in aircraft, but ethanol is not.
