Synthetic in engines and transfer case is good. Stay away from synthetics in differentials. Mfg's and racers will tell you this. Synthetic just does not cling or cushion like you need in differentials. 75w-90w is the same as 90w as soon as it warms to operating temp.----------------------"Q23. What kind of oil should be used with an Auburn limited-slip differential/ Auburn ECTED Max differential?A23. Non-synthetic 80w90 GL-5 oil treated with Auburn Gear friction additive, part #504102 (also known as a friction modifier). See Catalog page 32. Three (3) ounces of additive will treat one quart of oil. GM or Ford limited-slip additive may be used. We do not recommend synthetic oil. Auburn limited-slip additive is packed in every box with the differential."---------------------------
Um, I run synthetic in the race car in EVERYTHING. Well except for the water in the radiator . We break in with conventional and after that it goes synthetic. I highly suggest using the manufacturer's spec. Some pretty smart people put that out there for a reason, even if we don't know what that reason is.

Thanks hive mind. Trad gear oil it is.The rocket scientists and brain surgeons that wrote the owners manual don't have the torque specs in there. But, there's instructions on how to lock the doors. Time to call Toyota.
