I have a 2000 Nissan Patrol 4wd with a manual g/box and transfer case. The transfer case has a chain drive to the front drive shaft. Auto hubs on the front hubs.
It needs a less viscous, lighter oil. A heavier oil will cause the front output shift to turn even when in 2wd and the autohubs will engage which is not wanted.
Currently running Castrol transmax Z synthetic atf in it.
Have recently put penrite pro gear 70w/75 synthetic gl4 gear oil in it.
They have the same viscosity at 40° and 100°c.
Will the 70w75 gear oil offer any wear advantage ?
