We tested Pennzoil 75w140......Valvoline 75w140.....Redline 75w140.......and Mobil1 75w140, Synthetic gear oil in the diff......

Mobil1 was 25*- 30*degrees cooler then any of the others.....also it was. Very hot day....about 90*degrees......

We run a Quaiffe Differential so gear contact is very important to us....and we also use a cooler and filter on both the diff and trans to control the heat.

Hope that helps.
