Syn for the diff and A4?
Quick question - anyone have any experience using a fully synthetic transmission oil in their automatic? I've got a 2004 with 26,000 miles and am considering this upgrade. How many quarts would my transmission need for a complete "flush and fill?"
And the same issue for my differential, would a good quality synthetic such as Mobil 1 75w - 90 work in the rear end? Would I still need to add a bottle or two of the GM friction modifier? How many quarts of diff fluid would I need to figure on?
TIA.
