I have a 96 Tacoma 4X4 and want to change the differential oil front and rear and the transfer case. What kind of fluid is everyone using? It’s hard to find 75W-90 oil at the local auto parts stores. I have seen that weight in mobile 1. Any thoughts? Thanks
Valvoline 75-90 here as well and never had any issues over the years. I change it every 30,000 miles and it seems to work fine. Had my last Taco with 208,000 on it and always just used the Valvoline 75-90 in it.
if you have a little extra money I would spring for the good stuff. I have never used them but have heard nothing but good things about Mobil 1, Amsoil and Royal Purple. Like I mentioned before I have always just used Valvoline without probkems.
I have 135k on the odo and I have used 80w90 with no problems. The only thing is that in the winter, which is rather mild in TX, the gear shift is a little stiff when it is really cold until you get to the next stop light. Just make sure that you are able to loosen the filler before draining. I wound up rounding off the shoulders of the rear filler because the shoulders are so short - you cannot get a good bite on the filler with a wrench.
