Q: I just bought a new Chevy HHR auto that takes the E15 fuel as well as gasoline. I have never used the E15 before, and what I’d like to know is the good and the bad on it.
A: A lot of today’s vehicles are so-called flex fuel by design. The difference in the vehicle operation will not be noticed. There will be a slight drop in gas mileage, but power and performance will be unchanged.
