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

Can't answer the fluid question but make sure you can get the fill plugs loose before draining.

Mobile 1 is good stuff - I use it in the engine (5w-30), but stick with dino in the diffs/t-case. I generally see Valvoline 75w-90 stocked in the autopart stores over the discount stores.

Valvoline is 75w-90 is what I have used in both trucks with zero problems!

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.

I use AMSOIL Manual Transmission & Transaxle Gear Lube 75W-90 for my 5-speed 2003 Tacoma, which has worked out well for me.

I'm not an AMSOIL dealer; just a consumer...

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.
