[Vwdiesel] Rabbit 1984 1.6L Turbo ---- ( need help on lube ).

[Nate Wall]

GL-5 lube has extreme prtessure additives and  is
required for limited slip differientials, where gear
loading is exreme. Its the type and high percentages
of these additives that will attack bronze in
transaxles over time. Stick w/ GL-4. Redline MTL 90 or
another one of the Redline grades is best (I forget
the other one, the VW spec for weight falls right in
the middle of the two). "MTL", BTW stands for "Manual
Transmission Lubricant".
