    What is the best oil to use in my B5 RS4 please?
    Its got 5-30 longlife oil in at the moment but keeps leaking oil
    from the drivers side rocker cover. Its already had a new
    rocker cover gasket and also had some instant gasket aswell
    but still leaking. I wondered if theres a better oil to combat this
    problem and is a common fault?

    Thanks in advance

    you can use the thickest oil you want
    but you will still have the leak
    you need to sort the gasket etc out 1st

    Im going to sort the leak out with a new rockercover gasket
    but was just wondering if anyone has come across this
    problem before and what oil was found to be the best
    for this engine as ive spoke to a main dealer and they
    said 10-40 would be fine to use????

    DONT USE 10W40

    Its a semi-synthetic oil and will break your engine.

    The 5w30 Audi specify is far to thin for these engines.

    I'd be running a 5w40 or 0w40, in a good synthetic brand. Silkolene Pro-S if you want to splash out, or Audis Quantum Platinum if you dont.

    Get the car off AVS as well, or you'll be replacing the camshafts as well!
