Audi performing oil change - weight ?
I scheduled an Audi 8K interval maintenace appt. I told the service guy that I use full synthetic oil. He said I have two choices- first, use Audi's oil which is Mobil 1 0w40- or bring my own. I checked with the previous owner, and he said he always used Amsoil full synth 10w30- and said I could use 5w30 for winter.
What is the best weight, or does it matter?????
