    Personally I would do several oil changes over a few months, you just never know how many changes the car has had over the years, you could end up loosening a lot of sludge and then getting blocked & killing your engine. I've done about 6 oil changes on a 1.8T as the oil in the engine was thick & very black. I just kept changing the oil approx every 500-700 miles until it started to stay the same colour as when I put it in!

    I used Quantum oil for the flushes, then Mobil 1 once it cleaned up.

    ive never used engine flushes
    the only thing i do is run the engine until the oil is really hot
    before i drain it..
