Toyota diff lube options

Doublehaul · Dec 27, 2018

Hey Guys,

Sorry...but another Super Tech question. Toyota calls for 75w85 or a GL5 equivalent. 75w85 is not east to find at all! Any issues with going with Super Tech 75w90 Syn gear lube in the front and rear of the 4Runner?

Has anyone used this...is it a pretty decent fill? Looks to have the legit specs....

Not an issue at all. GL5 is what matters. Why are you changing so soon? Did you re-gear, install an extended breather kit and since you were crawling around anyway? When I used to do a lot of water crossings, (salt water and mountain rivers) I did a lot of profalctic gear oil changes. Never had water in gear oil (had xtended breathers).
Nothing wrong with swapping in new gear oil, I am simply curious what is motivating g you.
I have grown disinterested In Doing it unless I spend time in hub or deeper water.

Water crossings ultimately. Honestly though....just preventive too...i like to drain the factory diff fluids early to get rid of as much glitter as I can

Regarding the grade, there is no issue at all going from 75w85 to 75w90. Regarding the Supertech brand synthetic gear oil, Bryancc is right about the GL5 spec being what matters most. Any quality lube will serve you well, as long as you consider your usage (normal/severe) and keep to a reasonable service interval. It's like engine oil changes -- yes it matters that quality oil and filters are used, but a regular service schedule matters even more. My $0.02

Amsoil SVG/SVT 85 vs 90 IMO is meaningless nonsense.

75W-90 synthetic of your choice, unless your truck calls for Toyota Differential Oil LX and the diff calls for special LSD stuff.

Millions of vehicles running around and never had a rear diff change and never had a problem. After a water crossing, drive the vehicle home to get the fluid hot. Pull the fill plug and if it's milky, change it. If not move on. Diffs are sealed pretty good to keep dirt and water from getting in and oil leaking out. If water gets above the vent, that's another story.
