I switched my '85 1.9L to Mobil 1 the first time I did an oil change.  So far
it hasn't used anything noticable between changes in the past 20K+ miles.
Inspired by early good results with the Vanagon I put Mobil 1 in my '89 Honda
Civic (over 110K miles at the time) and was shocked.  It used (burned and or
leaked) the synthetic at almost double the rate of dino oil.  A low oil usage
turned into wholesale oil disposal.  All this in an engine that holds 3
quarts!  Switched it back to dino oil at the next change.
