I have an Impala that takes the cheaper biofuel, and I was wondering if anyone has actually tried the stuff? Does it mix with normal fuel existing in the tank? How is the gas mileage?
I am not a fan of the stuff, just on general principal (anyone seen the price of grain products lately?) but it is showing up at a few stations around here, and the price difference is actually worth noticing.
If the E85 is cheap enough to make up for the lower milage, then give it a try. You shouldn't notice much of a difference in everyday driving. From Chevy's website, the 2008 Impala sedan with the 3.6L V6 gets 17/25 mpg with gas and 12/19 with E85. So, if the E85 is 25-30% cheaper than regular gas you'll about break even, but have to stop at the gas station more often.
