I just placed an order for an Audi S4 with the 3.0 Liter direct injected engine with factory supercharger. Audi pays for the first oil change at 5000 miles, and then recommends one every 10,000 miles afterward. I will be changing it myself after the first free one, probably at 5000 miles again, and sending in an oil sample.
It looks like it specs VW 502.00 in 5W-40 (preferred), 5W-30, or 0W-40. I think the Audi dealers use Castrol SLX Professional, which isn't available to individuals as far as I can tell, and does not seem to test very well. My preference would be the Pennzoil Platinum European Formula (if I can find it reasonably priced) or Mobil 0W-40. I would like to use German Castrol, but it doesn't meet the viscosity requirements. I know technically it would probably be fine, but I don't want to have to worry about my warranty.
Any other thoughts or suggestions?
