OK, two vehicles, 94 S4 and my 91 200TQW. Both 5K miles since the change.; Beautiful cold starts, no oil leaks, much less oil discoloration (I think what there is was from the remains of the old oil left in the cooler-cooler lines-etc.) So, so far, so good. Paul Rivera 83 Ur-Q 91 200 TQW 93 S4 94 S4
