I am sure you all heard this question almosttt a millions of time but I decided to change the rear differential oil from my s2k today. And the only Mobil oil that I could find in many stores I went was 75w-90 GL-5. So my question is that is GL-5 good for the rear differential or not? please I need this question asap thanksss !!!!

 

thats what i put in 5-6k ago. no problems yet.

 

Thats what I use in mine. Not as thick as the LEwhatever but it works.

 

Ohh yeahh I forgot mention that the mobil 75w-90 Gl-5 is syntethic. But I will give it a try!!!!!
