Hi all Recent 50% off oil at europarts lead me into buying some petronas racer 10W/50 oil for my mk2 ABF track car Have not put the oil in yet and was wondering if anyone has had previous experience with this grade of oil ? I know the 50 rating of the oil is good for the high temperature of track use but I have heard people say that the thickness may not be good for the older engine design of the ABF and is only suited to newer engines So, what are other oils are you guys and gals using for track days ??? Thanks
