[QUOTE=etownfbplayer;2179ght my 2000 z-28 M6 from a dealership whom of which did all of the service to it. They were running a castrol 5-30 dino. I decided to switch to Royal Purple 5-30 full synthetic. Previously the car did not eat any oil, with RP i lost 2 quarts in 45 days. Its not in the coolant and the exhaust doesnt smell like oil. Does anyone have any thoughts please?[/QUOTE]
first if you read more of this thread, RP sucks, pennzsoil platnium is a better oil, As far a oil consumtion, if you run the car hard, ls1 are know for chewing up oil and should be checked often, The pcv system sucks on are cars and if you run the car hard the pcv system will blow it into the intake system and cause your oil consumtion. hope this helps a little
