I have been curious about using e-10 fuel (10 percent ethanol and 90 percent gasoline) in a rotary engine. It is a clean burning octane boosting chemical. It gives both performance and enviornmental benefit. I have wondered for a long time why here in the U.S. with the best technology in the world why we don't use an ethanol mix in our gas. Places like brazil have been using it since the 70's, they use 24% in their gas.



This would dramaticially reduce the emissions. Ethanol is renewable since it's derived from sugar containing plants that have been fermented, like corn, wheat, potatoes etc...



Ethanol is a high perfomrance cleaning burning substance that definatly should be appearing in your local gas station, especially with the rising prices of gas, hopefully soon. This would be the next logical step since just about any combustion engine can run 10%, but certain modifications to the fuel maps need to be done to run more than taht for older cars.



I think this would be perfect for rotary power cars since rotaries are not very resistant to detonation, a higher octane fuel has a much higher threshold and would reduce knocking and pinging, plus you could run more compression or boost with your setup, it's better for the enviornment, it's renewable, and it's cheaper.

The only draw back is that is slightly lower mpg by about 2%.

What do you guys think, personally this would be the next logical step before hydrogen. It's an easier step since gasoiline cars can run on it.

Rotaries are supposed to be able to run on anything, the only problem I see is a 2mpg drop is harder to take when you're only making 5 in the first place

No not a 2 mpg a 2% so if you are making 5 mpg you will get 4.9, because .1 is 2% of 5.

good luck with that.. if it started catching on more than it already has, you'd see oil prices fall down quickly because oil companies would start freakin.

****, 10% ethanol has been seen sporadically on sale here in Virginia for at least 20 years. It has not been widely available. If I had to venture a guess, it would be that "Big Oil" has put the kibosh on anyone who would dare to threaten the demand for their product, and therefore, their fat profits.

Where can you get your own ethanol to mix your own? do you need to worry about the gas and ethanol staying in solution with each other? And no, im not buying bottles of vodka or everclear to pour in my tank

the reason why with all this technology we arent using fuels like that is simple... big oil companies have power. way more power than you can imagine. they will do anything and everything in thier power to not let alternative fuels happen.

we have ethanol gas here, its doing a number on the older car's fuel lines as they were not intended to be running that fuel, never mind what its doing to the boats



then they gave us that MTBE which was supposed to be good for the enviroment, turns out it was bad for our drinking water, we get our water from underground aquafirs, so they had to stop selling it here.

haha yeah unless the car is made for it it will eat through all the plastic or rubber parts that the stuff comes into contact with...

the pumps around my home town have that 10% ethinal **** . there is no performance gain in it at all if anything there is a performance drop and also a slight loss in milege from what i can tell with my rx7 and dodge durango. i live in the emmisions counties so we have no choice in the matter at the pump unless i go out of county to get nonreformulate **** fuel, hell it even smells bad.



do rotaries burn it, yes, is there any gain in performance no! milege HELL NO!!!.



just my 2 cent
