I was just wondering, is it my Tahoe or is the estimated MPG on the sticker way off ?
Here is what I get:
City 12 MPG - estimated was 16MPG - that is quite different
Fwy 18 MPG - estimated and advertised 22MPG.
Average 13.3 MPG
I have also noticed that the Tahoe rarely goes to V4 mode. Typicaly only when I take foot of the gas or going downhill.
What is your MPG ?

i will get better with time.. the engine breaking in, and your habits of driving getting better about MPG.

with stock rims, i avg about 15.5-16.5 for mixed driving. still under the sticker (since i drive half freeway) but still not horrid. with my 24s on, i avg about 13.5-14 mixed.

i drove to colorado recently, and i got about 20mpg. realize, the biggest factor is your lead foot.. also, 4 cyl mode only kicks in when you have *very* light throttle. its only really effective in flat highway driving.

With 22's I'm averaging 13.1 MPG. Mostly city driving.

LMAO! HAHA, HMM. I must have fat fingered the 2 key, should have been a 1! How about 14! No, really I am not sure. I dont pay attention anymore, it is too disappointing!

I drive 100-150 miles per day on a mix of highway and city. I have had my truck two and a half months and have 12K miles. I have maxed the mpg at 18.8 on a 3 hr trip on the interstate and hit a low of 13.3 on back road driving. But the avg has been around 15.3 overall. Sitting on stock 20's

Also, people with larger than stock tires, the computer will read a little lower unless you have recalibrated for the larger tire.

I knew the mileage on the sticker was "pie in the sky". In order for the govermment to compare mileage to other vehicles (apples to apples) the numbers are based on totally unrealistic road conditions (basically as though your truck was in a giant test tube vacuum). Needless to say, I am still in the break in period and getting 12-13 mpg in the city. Not close to the claimed mileage, but will hopefully improve after I get a few more thousand miles on her.

I believe the government is changing the test to better reflect real world conditions sometime this or next year.

Yes, new MPG testing will be done. I believe it use to be someting like this. Driving 35MPH, no AC, windows, up, radio off. Somthing to that making, I AM NOT kidding.

THe new tests are supposed to have AC on some, stop and go driving, and some heavier foot accelerating! So I imagine we will see some huge drops! Be nice to see what they have on the 08's, we can then compare ours and see how the new testing is working compared to our driving habits. I guess this goes into effect in 2008? Anyone know?
