Hello everyone,
I have recently purchased a 1996 KZJ90 prado SWB with the 1KZ-TE engine, manual gearbox and open differentials (no LSD). The vehicle has around 272000 km and my priority is maximum longevity and reliability rather than performance.
Toyota documentation seems to recommend:
- 75W-90 GL-4 for the gearbox and transfer case
- 85W-90 GL-5 for the differentials
However, many owners nowadays seem to run modern synthetic 75W-90 GL-5 in the differentials as well (for instance, Motul Gear 300 75W-90).
For a long-term keeper J90 in a mild climate, what would you personally choose today for gearbox, transfer and differentials?
Thanks!
