Odd..........There must be some reason that the ethanol studies found this. I just can't put my finger on it...........

Ethanol ping........

I can’t imagine why the University of N. Dakota would find such positive results for ethanol.

I don’t buy this but have found the 10% blend gives better mileage than the previous one with MTBE.

I will love to hear Mobile’s rebuttal of this....

[Red_Devil 232]

Odd also ... no one sells the 20% or 30% blends. Am I wrong?

Higher compression ratios, higher expansion factor on the downstroke, etc.

Ethanol raises effective octane levels. If you could depend on 10 to 20% ethanol in the fuel, you could require Detroit to up the compression ratio on gas engines to, oh, about 12:1 from the current 9.5:1.

Research findings released today indicate that mid-range ethanol blends—fuel mixtures with more ethanol than 10% (E10) but less than 85% (E85)—can in some cases provide better fuel economy than regular unleaded gasoline, even in standard, non-flex-fuel vehicles

Hmmm Fuel with less energy will do more work. makes sense to me (as long as you repeal the first law of thermodynamics - something that Kongress has done with the CAFE standards.) Maybe that's how they found that you can get more work out of less energy. They ran the study after Kongress repealed the first law.

The optimal blend varies with the vehicle

Great, so you drive up to he pump, and enter your vehicle's make and model, and the pump mixes it for you.

Yeah, THAT's gonna work.

Or maybe each vehicle has a gasoline and an ethanol tank, and it mixes them itself.

Yeah, THAT's gonna work.

The results of this study seem to defy the laws of physics...

“The new study, co-sponsored by the US Department of Energy and the American Coalition for Ethanol (ACE)”

LOL! In other news, a study co-sponsored by Burger King and McDonalds found that fast food is quite healthy. :)

Just because the engines will operate without displaying emissions codes doesn't mean the water content in the ethanol won't eventually corrode metal components within the system. The first to go will be the metal diaphragm in the fuel pump, if the fuel pump is mounted in the gas tank, as most fuel pumps nowadays are. Fittings along the fuel lines headed from the tank to the engine are vulnerable, as are rubber hoses throughout the system.

My guess is it will take about six months to a year of regular ethanol use, in the quantities above E10, for rust and dry rot to begin to plague a non-flex-fuel vehicle.

I find the news in the article good news, however, especially the 15% increase in the Chevy flex-fueler. There are millions of these flex-fuel vehicles in the hands of drivers who are nowhere near E-85, but if blends of lesser ethanol content could deliver that much of an improvement in fuel economy, then the demand for it will soon begin in earnest.

My Research Assistant working on my next ethanol blend. It may take some time to complete this study, but I'll report back with my findings.

Exactly the opposite of my own personal observations in my Toyota.
