My New 7.3! MPG Questions??

Here Is my new 2003 7.3. I just got it monday, and now Ive been through a full tank of gas about 280miles on one tank, or 11mpg. Im totally new to trucks, especially diesels. As far as I can tell it have a Banks waste gate I beleive. It says banks Big head on it. It has 375/55/16 Mickey Thompson ATZs on it. the exhaust does not look stock. It also has a volant intake on it. I dont know if there are any other upgrades. also it is lifted, but I dont know how much.

I would like to know about some options that I have as far as getting better MPG. sorry that I dont have more info Im new to this. If you need more pics of certain things let me know ill post them.

Congrats on the new truck. The 7.3 will definitely not let you down. As far as MPG, a tuner with an economy setting would help you out with a few mpg's, as long as you can keep your foot out of it. The big tires of couse are not helping out with your gas but the truck looks very clean on the isnide and out.

I guess if I were you I'd see if it's got some sort of tuner or chip in it. Looks like it's pretty custom with all the gauges might have it on a tow mode

There is a tag on the rear differential. If you think the previous owner might of changed the gears. You roller the truck so one tire makes a complete rotation and while you are doing that have a friend check how many times the drive shaft rotates.

IE if you roll your tire once and the driveshaft spins almost 4 times, you probably have 3.73 gears. If it is about 3 and a half times you probably have 3.55 gears.

It also helps to mark the tire and driveshaft with some sort or paint or tape

Good lookin truck dude. Looks just like mine (except black). A tuner will help with improving your MPG`s, research the tons of them out there and pick what`s best for you.

That trucks got a lot done to it. THose tires are killing you though. Drop those to like a 13.50 or 12.50 wide and i would say you would gain 2-3mpg. Thats a lot of rubber on the road!
