I'll buy that tomorrow and throw it in, gets metter mpg with diesel kleen. Come on up, I bet with both our fat a$$es in it, I'd get at least 21.4!

Sorry to be a pessimist but maybe a 2wd vehicle single cab or something. I have 2 co-workers with 4wd Excursions 1-'99 with hypertech and intake he gets 16 highway 13 mixed, the other stock '01 same year as you, and he complains constantly he only gets 13 mpg.

Maybe we get crappy gas or they high altitudes here create issues but I have yet to see 20 mpg personally.

My inlaws ran a waste water company that ran in the remote oil fields. They had a fleet of over 15 F-250 powerstrokes ranging fromm 99-02 extra cab to 4 door and they say the same 15 mpg average at best. They just all swithced to Chev gassers except for the dedicated pulling trucks that are Dmax's. They said diesel just was not economical anymore for the fleet.

Nope, 4wd ex, only mods are in sig. I'm planning on switching everything over to amsoil in the next couple weeks for (hopefully) more mileage, and then when tax returns come in I'll get the TW chip for the econo tune. Can't wait for the results from that.

With two warm up periods, snow storm driving home last night, and another trip up to Augusta today, my avg mpg according to the lie-o-meter is at 18.1 when I arrived here. (when I jumped in tonight to come to augusta it was at 16.8 from the storm driving last night and warm up tonight)

BTW, that is with the cruise set on 55 on the highway in maine, and easy on the go pedal, with no bad weather, and winter fuel. She gets better mileage on the summer mix. I've turned into that guy that always used to piss me off on the highway. (you know, slow poke) Better MPG is a right lane thing. If I go 70+ on the highway, I drop down to 14-16 mpg, easy. Every 5mph is a 1+mpg drop avg from my experience.

One other thing, when I bought it in august with 81k on it, I brought it directly to the garage, and had all the fluids changed. (front, rear, t-case, tranny, motor, anti-freeze) I just turned 100k tonight. Wish I would have known about amsoil then, but I'm gonna do it all over again here shortly. All stock, with stock 265's

I'd suggest to your co-workers to look into their motors, and ease off the go pedal a bit. Good mileage is within reach on these rigs. (good is a relative term of course) Driving style is a very big factor.

I also reset the lie-o-meter at every fill up. I filled up last night on the way to gardiner (within 6 miles of the house), so that will explain the fluctuation in my MPG. Over the course of the tank, when I fill up next time, and I don't hit bad weather, LOM (Lie-o-meter) usually says in the 18.5 range, and thats with my lead-foot-wife driving sometimes.

I think the trick to getting 20 MPG is having 6 speed manual transmission, 2 wheel drive,highway treaded tires and drive like a little old lady.

I get 19 - 21 all the time on my 99 F250, 6 speed manual, 2 wheel drive (4X2), highway tires, synthetic oil, flat east coast highway driving. And yes I drive like a little old lady.

That might change soon, adding gauges, exhaust, DIY Air and TW chip soon. From reading about everyone else's mods, may be hard to keep driving like a little old lady after the mods.

do the larger tires cause poor mileage?

From what I've heard, yes. I want to do a lift and 35's, but I'm wrestling with myself on weather or not I want MPG, or a great looking rig. It's touch. For now I'm going for MPG.

[lilredpowerstroke]

I get a couple of gallons to the mile.

[taterstroke]

i get same mpg with 305/70-16 as i did with stoke 265/75-16
