Fairly new guy, 2 car's in my garage, 98 Stratus & 02 Malibu, very similar MPG wise. Played with E85 & E10 blends with Malibu last fall before finding this sight and getting a SG2, it pretty much no change in MPG at around 20% E, but only ran 3 tanks thru it(Davidk0031 on Fuelly.com). Playing with Stratus now about 32% E this tank and had best trip ever according to SG2 on way home tonight at 32.9.

Happened across that article and made me wonder. Also have a Flex fuel suburban that my wife drives 4 miles to work it gets 12.5 mpg on E85, 15 on E10.
Great site, I'm driving smarter, and trying to get wife & daughter to drive smarter as well.
