Anyone getting over 15mpg?

[bobbyg123]

The mileage appears to be lower than expected.

I have just over 3000 miles on mine and I get an average of 12.5 mostly in city driving, and I noticed it goes up the more the engine parts loosen up.

12.5?!?!

That's the hardest obstacle for me to overcome. I know it's a huge vehicle, but they should be getting better MPG than that.

Keep in mind the engine isent
really broken in until about 7000 miles, and being it is a 5000 LB vehicle I don't expect miracles either.

I agree, I had a Obs Tahoe weighed 4948 (2dr) and i got 14.5 in town and 17 highway . . Seams the newer a truck the better gas milage should be..

I am getting overall 17.8 mpg, considerable amount of highway driving but not all. I have +/- 14,500 miles on it.

Is that instant or adverage?

It's the computers average. I never figured it out myself.

That is pretty good than as at 4000 miles I get 12.5 in city, so E85 sounds promising.

My truck only has 1600 miles so it may get better as the motor loosens up.

I've got about 105k on my '01 and in town I average 13MPG, on the highway/interstate I get 16.

I'm sorry, I just noticed this forum is for 07+ models. Please pardon my noob mistake.

Doesn't really matter to me, we're all friends here. BTW, I am interested in your mileage just casue I wanna know if there is a big difference between your year and the new 07. Doesn't seem to be.

Hi i am a new guy as well , I just put an 02 on the road,First tank i got 312 miles with 19.8 gallons of gas. Thats 15.7mpg with mixed driving.

It has 5.3 engine,and a 3:73 rear end..

Now people say even that is bad gas milage,I think it is good milage.You have 5000 pounds in these trucks,And can move it over 79 thousand feet (Approx 15 miles) with about 7.5 pounds of fuel.Not bad in my opinion I bet if u tied a horse or horses to 5000pounds you would feed them a lot more then 7 pounds of hay to pull it 15 miles ...

I keep saying the same thing considering our big comfy trucks weigh twice as much as a Honda.

Does it make a difference if you put in 2wd instead of awd?
oh and I'm getting 13.6 and climbing@ 600mi.

 

[calientecafe]

My first tank was 14.7. Second tank is 16-17. Freeway is 22.

my average according to computer in my tahoe is 15.5 mpg. Thats me with a heavy foot stop and go and conservative driving on the highway. Looking to adding a Flashpaq tuner by Superchips hoping it will increase my milage as well as performance
