I have an early 07 (4.3 liter) with zero oil issues, but then it only has 174,000+ miles. If I change oil at 5,000 mies, it is down about 1/2 quart at oil change.
So far repairs equals - one new clutch at 170,000 miles.
My only gripes are the damn spare tire holder and the heater controls. They must have been designed by an accountant. I'd like to shove that spare tire carrier up where the sun doesn't shine.
