F250 gas mileage

Hey guys i know this has been posted many times but i need some advice about my mileage. Ive got an 02 f250 with 7.3 turbo, 35'' tires, no lift, DIY intake and a 4in exhaust to 5 in tip. Also it has a predator economy tune. MY overhead says im gettin 21 mpg. manual figuring im gettin 14.8. Is there anything i can do on top of this to get more mileage? Thanks.

Quit putting gas in your tank apparently.

Seriously though, the tires are killing you.

Also, run some cetane boost through your tank every fill up. I'm averaging about 18 right now city/highway mix.

Can't say i'm 100% sure. I can say that I have been at LEAST doubling the recommended amount and doing about 8 ounces every time I fill up with no ill effects (so far). I'm in Alabama where apparently the cetane is crap (or so I'm told) so I just add and go. When was the last time you added the booster?

If that is city or highway/city driving your probably not gonna get much better(esp in winter) with the tires cause Im running 35's and I have tried everything and cant get much more than that around town with a little highway. I have run Diesel Kleen in the last 6-7 tanks and it helped a little.

Yeah, you will drop a little due to winter diesel. Check the fule/ air filters. Sounds about right though. Im actually a little under that, im running stock tune though. Highway i can get around 19.

My 2000 F250, 2WD, 20" tires makes 14 miles/gal in city and 17.5 miles/gal on freeway at 60 miles/hr. The truck is plain stock. The only mod is a DIY air intake and a BTS exhaust. My driving habit is very conservative keeping it under 2K RPM most of the time.

I tried DieselKleen and found zero improvement with mileage. I am using TWC-3 2cycle engine oil mixed in diesel fuel at 1 oz per gallon ratio. That does not improve mileage but it does make engine runs smoother.

Next move is to replace the 20" tires with the original OEM 16" wheels. I hope that would provide better fuel mileage.

tires and stay out of the boost are my reccomendations. i also hear seafoam in the fuel bowl with a new filter helps. filler-up then run for a few minutes so the stuff gets into teh injectors, let it sit for a few hours or overnight.

I just checked my milage over the weekend on a road trip. I got 16.75 mpg. That's hand calculated. That's on a 2000 f250 7.3 with 34" tires , 4:10 gears and a front 2" leveling kit. Everything is stock on the truck except for a superchip in performance mode. Up here in Minnesota we're still burning the crappy winter blend fuel. I was getting between 12-13 mpg before the superchip I'm sure mpg it will improve more as weather warms up.
