    Thanks but I thought we were supposed to use 75w-90 not 85w-90 - don't know if it makes that much difference or not - does it ?

    When I had my 5 speed, I tried the MT90 and didn’t notice a difference either, but I guess it has additives to protect the synchros. Who knows? Probably just marketing.

    I don’t believe it makes any difference. I also tow a trailer a good bit. The manual calls for a GL3 or GL4 oil. Most you find are GL5.
    I also run run SuperTech 80-90 in my diffs. The only synthetic I use is in the transfer case.

    The Stalube has no sulfur in it from what I can see.
    This is from my manual:

    I run 85w140 Lucas in mine and i havent had any issues. It's a little bit stiffer to shift when its below 30* outside until it warms up for a minute or two. After that i can't tell a difference from the 75w90

    It was 20F today and not even Thanksgiving yet - think I'll stick with the 75 - I like somethings stiff but not shifting. Thanks.

    Awesome CB setup, TRD leaf springs, matching camper shell...more to come some day.

    Any GL-4 will work fine ..a GL-5 that is formulated to help with yellow metals will do just fine as well



    I have been using MOBIL 1 for about the past 25k miles.... No issues. (2.7L 4X4 Manual Trans)
