What are the best or mixture of Gear Oil to use?

 

Hard to beat amsoil severe gear.

 

Redline MT90, 3 quarts. It's actually 2.9 quarts.

 

Amsoil severe gear

 

Depends on the transmission.

I run MT-85 in my five speed track car.

 

Amsoil hands down

 

How about for a DD Evo with the occasional weekend drag/auto-x but mostly just DD.

 

AMSOiL 75w90 Synthetic in the transmission
AMSOil 75w90 Severe Gear in the transfer case/ rear differential.

been running this oil for 20,000 miles (changed at 10,000 mile intervals) with no problems, actually very smooth in the transmission.
