Happy I switched to diesel
By SLC, UT on


2008 GMC Sierra 2500HD SLE1 4dr Crew Cab 4WD SB (6.0L 8cyl 6A)


I traded in a 2004 F150 4.6L with 25,000 miles to get a 2008 GMC 2500 6.6L diesel. The performance is unreal. I am getting over 13 mpg, which is the same as the 150 on Premium and I get 3 times the power. The ride, fit and finish are as good or better and the information center is a real boon. The shakedown will continue for another six months but for the first 30 days I could not be more pleased.

Best Features

The info center and the rear seat room are real improvements.

Worst Features

Standard under the rear seat compartment would be great, to keep paper towels and small items in place.
