You burn MT 90 in a vanagon motor?  Does that make it last longer? (grin)

  My last oil change for the inline four VW 1.8 liter gas motor in my
Vanagon I changed over from 10-40 Penzoil to some Castrol 20-50 and my
slight oil leakage (pan gasket) has diminished dramatically.  I was
using/leaking about 1 qt every 2-3 tanks of fuel but with the heavier
Castrol I am using about 1/2 that...
