Mobil 1 oil weight

[Steve Marinello]

Personal experience with one urq and two S6's; one stock and one 
RS2'ed...forget the light oil.  Great for the newer cars, but not our 
old I5 turbos.  !@#$%^&*Dealer didn't use the 5W50 M1 I brought and put 
the light stuff (Kendall) in all three, and all three blew out or burned 
a quart in the first few hundred miles after NEVER burning a quart in 
2500-3000 miles between changes over twenty years.  I wouldn't go near 
anything lighter than Amsoil 10W40.

YMMV, but I don't want that light shit anywhere near the older cars.  
Fine stuff for the 2.0T in the GTI, but keep it away from my I5 turbos.
