Started burning oil after 22K miles.
Burns 1 qt every 2000 miles and GM
refuses to fix. Gm claims it is
within specs to burn over 1/2
crankcase capacity between changes.
Engine has great power and truck has
been reliable. Except for crappy oil
burning engine it has been a good
Power - lots of it
Burns lots of oil and GM has twice
increased the oil consumption specs
higher since I bought the truck. They
will not fix the engine!
