Most of the Vanagons experience a problem in the oil flow and with the
switches, synthetic oil cures that - or part of the problem.
VW recommends an oil / oilfilter change every 15000 KM or about 9000 miles.
synthetic cost 4/5 quarts some $12 and $8 for the filter and gasket so by
skipping your fathers advice changing the oil every 3000 k you would
probably save money and do something good to your
engine
