Rear diff an 4MT Gear Oil.....

Recommended Posts

Can I use the same oil for the rear diff AND my EA81 4spd tranny?

 

Time for a complete lube job. And im installing a welded rear end, so i need to fill that with oil. Is there "special" gear oil for a manual tranny?

 

Im thinking Castrol 85w90 off the top of my head.

Yep, 85-90..that's what I 've got, although the xmission juice is synthetic. Quite a difference on those cold Tahoe mornings in January.
