Just went and looked at the TSB and I just got my numbers confused, meant to say 75W-85. Haven't seen anything about 80W-90.As far as the 80W-90 comment like I said I called 3-4 local dealers around me and they all stated they use 80W-90 and only one even knew about the TSB. It came with 80W-90 if you have an older FJ (mine looked like 80W-90 when it came out) You have to understand at most dealers they don't care about things like this. They have a ton of the 80W-90 in bulk so they continue to use it.
Hmm, makes me question just using 75W-90 now...gas mileage is important to me, but being a college student I don't really have the money to shell out for a case of 75W-85. Guess I'll just keep using the 90 and switch it to 85 when I have a real job :clap:
And is it supposed to be 75W-85 for front diff, rear diff, and t-case?
