re: Does anyone use the Flex Fuel E 85 in their vehicle?

For the record the gasoline you are using is not E87. The E in E85 refers to the percentage of the fuel that is ethanol. E85 is 85 percent ethanol. 87 gas is 87 octane and about 15 percent ethanol. Ethanol percentages in e85 change during the winter and can go down as low as e70 during the winter due to cold starting issues. Which is ultimately better for mileage. Like was said above, it's pretty much a wash on price because e85 needs more volume of fuel to do the same work as gasoline.

A lot of people with performance cars love e85 and I even buy barrels of e98. If your car is set up for it,it is a wonderful fuel. It burns cool, has high resistance to detonation and is basically a cheap race fuel.
