Volks,
I have a simmilar tale to tell. My 85 westy with a 1.9 l boxxer  currently has
235.563 miles on the odo .I'm the third owner and my father (who can't tell a
combo wrench from a screwdriver ) was the second .I've got all the service
records  from the PO and the only serious work other than tune ups , was the
head gaskets .
The van gets between 19 and 23 mph  depending on time of year and amount of
highway time . The oil of choice at this point is mobil 1 20-50 . Changed
every 3k with a new factory filter insalled at the same time.This helped with
the slightly low oil pressure and stoped a small amount of blow by .Currently
working on installing a gti motor , Have ALL the diesel stuff cleaned and
ready to install but just found a crack in the case of the doner engine . back
to the hunt !!!
