2008 GMC Sierra 1500 SLE2 4dr Extended Cab 4WD 6.5 ft. SB (5.3L 8cyl 4A)
Bought pickup through GM Employee Pricing sale and got very good deal. Not quite sure about pickup, as you can feel the 4 and 8 cylinder activating and de-activating. I have experienced the tranny jerk from a complete stop as well. After changing oil I can smell oil in the cabin for at least the first 1,500 miles before going away, cannot find any leaks anywhere.
Went with GMC over Chevy as it looked nicer overall style wise.
Forget the active fuel management, and stick with basics, I am getting worse mileage now than I did with my 2005 Chevy crew cab and that was a heavier vehicle, I should be getting better economy now than before, going backwards.
