I do not understand the need for this. Is it just Toyota. Most just use 75w90.
It’s getting popular. My Subaru has it too. Trying to squeeze out another .001 mpg!
i guess my point is, 75w90 and w85 are not that different,
Engineers at Amsoil are probably smart enough to run their factory fill for a decent duration. Not everybody has a guinea pig to test on in 2017.
What is it, an LSD? Doesn’t make a lot of sense otherwise. Some fluids will quiet noisy diffs, but those aren’t ots fluids.
Congrats!!
Almost certainly was not the viscosity since it is temperature dependent, and that a 90 grade gear oil that’s possibly as little as 10* hotter will be the same viscosity as the 85 grade oil.
If that is specified yes.
The Amsoil site needs updating, as the data is from earlier 2024. Either would work.
Most Toyotas are much happier with GL-4 75W85 (if you mean MTF). I tried to order 2 quarts from a Nissan dealer-they decided I didn’t need it! “No one ever changes that!”
Or the price to come up to where Amsoil doesn't seem so expensive.
I use severe gear 75W90 in the xfer case in the Pilot.
Next oil change (75k miles) I’m doing the same on my ‘21 3.0. Just FYI, the transfer case calls for LV so you’d want to get the fuel efficient ATF fluid for that application.
