It's a mixture of 85% ethanol and 15% gasoline, commonly referred to as "Flex Fuel". The regular gas you get at the pump normally contains around 8% ethanol these days.
e85 is generally sold a good deal cheaper than gasoline, is becoming more and more available in the US (can be bought at the pump at many gas stations), and performs like a race fuel when properly tuned in a turbo charged engine. It burns considerably cooler and has a high octane rating. Due to the properties of ethanol a tune can be pushed pretty damn hard before you start seeing knock, if it ever knocks.
Typical power gains for a WRX on e85 are +50whp and +70wtq, give or take 10hp..
Yea, in the US we generally make it from corn. They've been running it for over a decade in Brazil where it's produced from sugar cane. One of the big complaints about it is that it supposedly takes more energy to derive it from corn than it contains, although I believe they have improved the process in recent years, and it's much easier and cost effective to use sugar cane.
In case you didn't know, ethanol is the alcohol you get drunk off of. A bottle of Everclear is e100.
hmm, anyone wanna start moonshining??
For gas saving of course =]
Maybe we should start looking into other energy sources such as this for our gas instead of electric diesel hybrids...I kind of like hearing the sound of my engine...and the sound of other cars before i cross the street and not getting t-boned
Cali is strict with everything though
Brasil is my country mann lol... you can find ethanol everywhere ...its made from corn that why the corn price went up as an alternative to gas... but don't you have to make your car special to run e85?
I assume it couldn't be too much
I'm gonna start planting some corn in my yard and make myself some free gas
