Thanks! Hoping to find out what others are actually using.There are many threads debating this back and forth. Search the forum.
Hey my friend, I was gonna text you. Let's get specific. Are you gonna use the same viscosity in the diffs and transfer case?Ravenol MT3 is in there now. 4 quarts of HPL are on the shelf for the next change.
Happy to text. The 75W is for the transfer case.Hey my friend, I was gonna text you. Let's get specific. Are you gonna use the same viscosity in the diffs and transfer case?
OR are you gonna use the 75W in the transfer case?
Yep, I'm sorta in the same boat. I got 8 gal of HPL oil and only 4 qts 75W-90 gear oil left.Happy to text. The 75W is for the transfer case.
The truck specs, I think, a 75W 90 in the rear end, and a 75W 85 in the front differential. I will use the 75W 90 in both.
I’ve still got some AMSOIL on the shelf, but I’ve also got a bunch of HPL 75W 90 gear oil for the next change.
If I did not have a pre-existing stash, I would have nothing but HPL in the truck now.
The Ravenol was all I could find several years ago when I changed it.
HPL is less expensive, and I like supporting small businesses.
I have the same Toyota memo from a few years back. 75w-90 is good to go.75w90 in all 3 and dont lose sleep over it.
this was from toyota directly about the transfer case. so dont over think itView attachment 181012
It is. But there are some 75W–90 fluids that are both GL5 and GL4 such as HPL and some Ravenol.I thought a GL4 fluid was preferred for the transfer case due to being safer on yellow metals?
