Re: 2007 Silverado Using Oil
This is odd. Never heard of it. But sorry to hear of your problems.
My 1993 Silverado with the 5.7 started burning about half a quart by oil change time at 4000 miles, but this was only after it had over 120,000 total miles on it.
My 2002 Silverado with 5.3 never burned a drop of oil - even at 150,000 miles.
I had a 2010 Silverado with the 5.3 and active fuel management on it. That did not need any special oil, but I used Valvoline synthetic. Only had 2 oil changes on that truck, then damaged bad by hail and traded off, but to my knowledge it never used oil.
The 2011 Silverado crew cab with the 5.3 I have now with active fuel management does not seem to use any oil, but these (at least the 2011s) are now required to use GM Dexos or full synthetic.
I would maybe try a different oil. I have had good luck with Valvoline full synthetic.
