Everyday driving I'm seeing 14-15. One highway trip I got 19... I only have 1500 miles on it and I expect the MPG's to get better.

I just bought a 05 GMC Crew 4X4.  I'm getting about 14 to 15 MPG.  What is everybody else getting.

 

 

 

 

19 Highway unloaded

9-11 towing 14000 lb trailer

 

I have noted milage is about 14 cold improving as the engine warms to operating temp

I only wish that I could see the mileage some of you guys get. The very best I have ever seen was 16 cruising 70 down interstate. I don't have the DIC so I have to hand calculate it but I have heard that they can be off. I normally see 14 with my 12 mile trip to town and back. If I ever saw 18 I would jump for joy.

I'm seeing around 15 on average on my 05 crew cab HD 4x4 . Just purchased a Diablosport Predator Programmer, hoping to see a bit more, I'm looking to get intake and exhaust soon.
