LS1 OIL CONSUMPTION
I have to add 1/2 a quart every 1000 miles. Has enyone had this problem? or does anyone know what could be the cause?
Ring flutter has to be a consideration in M6 cars.
I think I've solved the problem by using a Penzoil semi synthetic 15W50....only used 150ml this change period....give it a go. My car used to guzzle 5w30 and 10W30.
