2004 Chevrolet Tahoe LS 4WD 4dr SUV (4.8L 8cyl 4A)
We just bought our Tahoe and I absolutely love it! I have to remember to take it out of all wheel drive when I first get in, so that I'm not using to much fuel. In doing this, it takes me from 15.9 to.. the best so far is 20.6 mpg. But, the average is 19.7. Hope this helps someone. Not all of the 2004's I've noticed are like mine. Mine has 3 buttons to the left of s/w. 4 Low, All wheel and the T/C. I hit the T/C before putting in gear, this is what helps with the MPG.
Haven't found one that I don't like
Take the OnStar off of the steering wheel. It's not available in all areas, and could use the temp controls there instead.
