True, but my concern is the wet clutch. 30 weight oil from the 70's and 80's is substantially different from the modern oils. Oils now have additives not available back then. While possibly good for the engine parts they are not good for the clutch. I have seen wet clutches destroyed by modern oils. Thus my experiment as you call it.

Actually Robert Hess, our Canadian equivalent of Don Moyer recommends 10W40 oil for use up here because of the operating temperature in which the A4 is expected to run in our colder water.
