Has anyone tried both at 75w/90 and have any opinions/thoughts/reviews on how each performed for your differential?

 

I like redline oils. I use motul engine oil and redline diff and trans. Cant go wrong with either.

 

I have only used Motul for my rear diff, and used to use it for my front diff too for years, switched to redline on the front diff about 10,000kms ago.. I only switched because I couldn't find the Motul locally when i was doing the drain and fill....haven't noticed a difference

 

Both are quality fluids.

My last trans/diff change was with Redline. I might give the Motul a try next time. I have some grinds when the car is started/cold.

 

Thanks for the input guys. Was just curious how those who've switched from either one felt about each fluid seeing as how I've heard both are quality fluids. I've used redline before switching to Motul recently. I feel no difference so far.
