Whats your MPG's?

Hey all, I just recently replace high pressure fuel pump and my mpg's have changed drastically!! I was getting 13-14 mpg, now i'm getting the upwards of 18+ driving to work and my gf was bragging about her 18 mpg in her 2007 Chevy Tahoe. If that ain't a smack in the face getting beat by a 3/4 ton truck. The truck is completely bone stock. 2008 6.4l supercab.

What's everyone else getting?

Thanks!

I average 16mpg with my 08 supercab. How many miles were on your truck when you replaced the fuel pump.

Hi,

I have an 08 f250. I was getting 10 to 12 mpg. I did an air intake, dpf delete, and spartan turner. I have also done a transmission and head gasket with head studs although I don't think those have anything to do with mpg. I am now getting 16 to 17 around town and 21 to 23 highway. Plus my truck is now really fun to drive. I'm getting an air dog fuel pump next.

Pre mods, I was getting about 11.7 in town...I hardly ever take it out to the interstate. Now I have been as high as 19 in a 1 ton 4x4! My dash is damn close to accurate!

so do you all take the 5 minutes time or so to get the last 4 gals in or do you calculate at the first shut off......unless its to about to overflowing those numbers are bogus....but they let you sleep well at night.

odometer and receipts. You can follow me around if you want.

438.5 miles divided by 24.4 gallons is 17.9 mpg


16.2 mpg



17 mpgs

I believe that, but not people who claim 23 mpg. Why do y'all run the tank down to E when the 6.4 fuel systems are so picky? I always stick to the 1/4 tank rule but that's just me
