Let me also chime in for 20W50 and Mahle/Mann filters.  I run this year-round,
including Pennsylvania winters (often down to singe digits �F).

The filters do not need to be from the dealer.  I got my last batch from Jim
DiGennaro when on his way to a VW show for less than $4 each.  I believe the
Bus Depot has these as well.

FWIW, this 2.1 engine just flipped over 200K.  Oil pressure is at least RPM/100
in psi (i.e. > 20psi @ 2000RPM) when hot.  I really like having an analog gauge.
