Hello
My 99 yukon 5.7 has been consuming about 1 1/2 quarts per 3000 miles. Is this common? I have inspected the engine for leaks and haven't found any. There is no noise coming from the engine and the truck seems to run fine. Also, there is no smoke (blue) coming from the tailpipe that I can see. Is anyone having this issue and is it common to use that much oil? The truck has 133,000 miles on it and is in perfect condition otherwise. The dealer has changed my oil since I bought it with 33,000 mile on it. I have run Mobil 1 in it since day one.
Thanks Brian
