Question

what kind of mileage do flex fuel cars get

Answer 1

The ethanol has a 70% "development" if compard to petrol.

even though ethanol can take high compression levels, what makes the power and the eficiency of the engine rise, as it has no high caloric power (as petrol do), ethanol has a greater consumption.

TO calculate which one is better for your car you may:

Petrol price * 70% = X

Ethanol price = Y

if Y > X or Y = X, it's not worth using ethanol. If X > Y, so yeah.

Did it aswer your question?
