11 mpg since day 1. The 88 F250 460 work truck gets about 12-13 mpg with the same driving habits and it gets premium.

Somebody on one of the forums said to use GM F17250 donuts (slightly thicker, Squeeze down on worn pipes) in place of the Ford parts(40.00 here), I went to Napa to pick em up and they had replaced the GM parts with Fel Pro P/N 8194 (7.34 a pair), looks like it'll work a lot better than the Ford parts, The post said lube it up good with high heat anti sieze and it'll squeeze the pipe nicely, Looking at it I'd say it's gonna work, Hopin for no rain tommorow.

Cool, i noticed a little blow by on mine, maybe i will have to put on some of those this spring when it warms up outside. The only problem is my studs on the connections are gonna be a biach to get off. Do they blend fuel in florida for "winter specs"? I wouldn't think it would be the same as up here in MN.

So what pipes are you talking about? The turbo pipes?

I don't think so. I buy my fuel from Flying J most of the time. But when I am not close to there, I just buy from the cheapest local guy (usually Hess)
