    Has anyone used 75W90 in their rear differentials?

    The manual calls for 75W85, but Motul/Amsoil vehicle selector shows 75W90

    AMSoil vs Motul, which one is better? Looking to do a diff oil change soon.

    I like amsoil severe gear, but I've never used motul.

    ^^^ Any different feel with AMSoil in the diff? Soon at 10000 will change motor oil and diff. So far every other vehicle in the family has AMSoil but me...

    If you think changing out the rear diff oil will change the 'feel' of your truck, I have some really great blinker fluid to sell you.

    Only way you'll 'feel' it is if your old oil was way past due for changing, in which case you've probably already damaged your diff from it.

    It doesn't matter one bit. In fact Walmart's Supertech brand (made by Citgo) is as good as either--especially their 75W-140 full synthetic--I've used it in Miatas, Mustangs for years...

    Mine's been fine. I changed mine at about 4000 miles.

    I've always been a Valvoline guy, but use Mobil 1 in the crankcase. This is for 8 off-road vehicles.
