this has been the Choice of oils for many VW/Audi racers. it has been approved by VW/audi and mercedes and BMW for a long time now...this is the oil i;ve used for about 4 changes. great stuff....you all know that i store my TT for the winter right. well anyway when i let it store even for the winter plenty of syn oil is still on the crankshafts and it starts up without any problems. good stuff.
