Having problems with your GMC Denali ?
My 2006 envoy denali 5.3 engine is using an eccessive amount of oil. I can change the oil and then check it at 500 miles and its still full ,I can check it agian at 600 miles and it may be 1 qt low.. It has used 3 qts in one week.. Car has 85000 miles on it but this has been going on for a long time. Doesn't leak a drop...WHERE IS MY OIL GOING , If I drove for 2000 miles without checking it would be empty. I know the idiots at GM says 1 qt every 2000 miles is normal. Mine is using 2 or 3 times t
