Must be a BMW owner thing with your I'm right and no other opinion matters attitude. You're right that BMW, Audi and Mercedes are different. Well...DUH! They all do however have 4 cyl. turbo engines and are similar in car weights, performance, etc. unlike your smartass Cummins comparison. Real brilliant. Oh and the Mercedes C250 uses 8 quarts of synthetic and still recommends changes at 10k miles. The oil weights/viscosity will be similar among mfgs. and have more to do with the oil breaking down than getting dirty. Perhaps Toyota is not the best example but Audi and Mercedes are as close as you can get.
