Volks,

After changing from winter to summer tires on me moms 94 VW Vento, I
also pulled the oil dip stick, to check the level. It was plenty of oil,
but the oil was more like black syrup. How do I wash the engine, on the
inside? I can think of one way to do it, buy 20 liters of cheap oil, a
couple of filters and change oil once a week 4 times, and fill up with
good oil. Does the list think this is a good way to do it, or should I
do it in any other way?
