I have only done like 4 thousand miles in my car and i have topped it up at least 3 times! and today my oil light came back on again! i dont think there is anything wrong with it, but ive heard that A4s use loads of oil for some reason, but why? and that castrol edge stuff is expeeensive! 50 quid for a canister whaa! I did use the search, but it didnt find anything!
