...in trying to figure out if this is worth it. My car, 06 Impala, is a flex fuel car which means I can use either regular gas or E85. I noticed that E85 is 50 cents cheaper than regular gas. I'm trying to think green in both ways of keeping money in my wallet, and using what is best for the environment, which I'm hearing E85 is. I looked it up because some people were against it because the fuel efficiency is less. When I looked it up it said it is 20-30% less efficient than regular gasoline. So what I'm looking at here is saving 50 cents on each gallon, but 20-30% less miles per gallon.
Is the money I'm saving worth it?
