Picked up a facelifted S3 a week ago and thoroughly enjoying it. Just a quick question:
Oil was changed with Quantum stuff (fixed service not longlife) recently but noticed today that it could do with topping up (towards the bottom of the "dotted" area on the dipstick). Can you mix oils? I have a litre of unopened castrol edge fully synth 5w/30 lying around in the garage from previous car and wondered whether I could stick some of that in?
Probably a stupid question, but don't have a TPS / VW / Audi garage anywhere near!
