MPG suggestions
I just bought my first diesel, 2000 F250 with a 7.3. My first tank of gas was mostly around town with about 70 miles on the highway and the rest in the city. I averaged 11mpg and was wondering if this is normal and if not what I can do to boost it a bit.
Thanks for any help you can give me.

Welcome to FTE!! you'll definitely save money by spending time on this site!!
My '02 is getting 13-14 around town on a lot of short runs. Highway mileage runs as high as 19-20, depending on how patient I am about staying at or below 70 mph.
Couple of other things Rampage didn't mention is the zodad mod and the removal of the air intake heater (AIH delete mod), which requires a plug to close up the hole. DieselSite has them for $8 plus shipping. Other folks have used a standard oil drain plug that is, I think, 22mm, and is a lot cheaper.
Here is a link to several good page swith lots of maintenance and mod information.

Tire sisze is the biggest factor in fuel economy, I have the 235/85's and they give me 19mpg on the highway and 15-16 city, IF I keep my foot out of it...
Is yours 4X4?

O.K. everybody stop.... ryanmack55, first, DONOT LOOK AT THE LITTLE COMPUTER THINGY ABOVE YOUR REARVIEW MIRROR. IT LIES. try to calculate your mpg by calculator. fill up, reset trip meter, drive, fill up, divide miles driven by gallons pumped. I think you will see that you are getting better mpg than you thought (if you were using the lie-o-meter). I am getting 16mpg mixed driving with the setup in my signature.
