| Re: 2005 CTS Oil consumption
if your under warranty and burning oil. get to the dealer and demand they do the engine cleaning process.
GM has a special part number for the decarbonizer which will free up your rings.
I just make sure i give it a pretty good rip once a day on the on ramp. I put some ring free stuff in the oil and seems to be a little better but i burn a half quart every 1500. |
