    Hello, I would like to change the differential oil for rear! I look at manual and found out below information. The temp in my area is mostly cold but Not going below 0 F.
    But, Is it SAE 90 is different from SAE 80W-90? How to read number correctly?

    Thanks

    Recommended oil viscosity by Manual:
    Front SAE 75W−90
    ==============
    Rear
    Above −18_C (0_F)

    SAE 90
    ...
    Below −18_C (0_F)
    SAE 80W or 80W−90

    ====================
    Mobil 1™ Synthetic Gear Lube LS: [ FROM Mobil 1. Website]

    Mobil 1 Syn Gear Lube LS 75W-90 meets or exceeds the requirements of the following industry specifications

    • API GL-5

    You'll be fine with an SAE 90 or 80W-90 or even the Mobil 1 75W-90.

    Personally, I use Lucas 80W-90 conventional oil since it's available at a pretty low price, as do a lot of folks on here. But there are a lot of people who also use the Mobil 1 75W-90 that you've found, since it's synthetic.

    When you do the job, don't forget to loosen the fill plug before the drain - just so you don't end up draining all the oil and then end up not being able to open the fill! :)
