Ethanol Hurts Gas Mileage
Supporters of ethanol use say it’s a cheaper, cleaner burning fuel. They claim the 10% blend has virtually no impact on fuel efficiency, but some mechanics disagree.
Block says it’s simple science. He says a car must burn more ethanol to create the same energy as gasoline. So if you remove 10% pure gasoline and replace it with ethanol, the fuel won’t burn the same.
According to Block’s numbers, the driver of a vehicle that gets 20 miles per gallon would see his fuel efficiency drop to 19 miles per gallon on average.
Hmmm. This sounds familiar. Seems I read someone saying something like this not too long ago. Oh yeah, it was me.
Not to mention that Ethanol blend gasoline makes many cars (like mine) run like crap and causes them to burn MORE gas which makes people spend MORE money at the pump.
One MPG difference can have a significant impact over course of a tank of gas. For the record, by my calculations a 10% Ethanol blend causes me to lose a little over 2 MPG. In my case thats a days commute to work and back. Thats one more day I can go an without having to buy gas. Over a few months that adds up to a couple weeks. Over a year that adds up to… well, you get the point.
