I haven't checked the mileage yet, 'cuase I haven't filled up again, but I put a half tank of E85 in my 05 Ranger, my dd, in less than 10 miles my check engine light came on. I went and filled up the rest of the way with regular. I figured out, assuming a 17 gallon tank, to get to the 40% maximun of alcohol I will fill up next time with 10.2 regular gas and 6.8 E85. I'll check my mileage and repost. It seems to run fine, buy it kinda smells like a hospital!

I would rather suffer the consequences of a Conservative?s error, than suffer the consequences of a Socialist's intent.
