Ethanol can help raise gas mileage

Perhaps ethanol does distract from raising gas mileage in the minds of some, but it could actually help with mileage. What the article below fails to mention is that cars can get much better mileage on 85% ethanol by taking advantage of the much higher octane levels in ethanol. The Saab 9-5 biofuel, already on the road in Sweden, uses variable turbo boost to get better mileage on E85 (85% ethanol). Ethanol's higher octane allows for a much greater boost and better mileage. -- Jeffrey Goettemoeller
