3rd Gen Tundras 2022 UP Differential Fluid Change

Hello all. I tried to search and went through about 10 pages of scrolling looking for this topic. I did try to do a search. Either I over looked topic title or its so far down I’m not going to spend 10 more minutes entering in searches guessing at titles or looking through pages of posts. Iit’s just way easier to make a post.
What diff fluid do the 3rd gen Tundras use, at what mileage (service interval) and how much fluid to fill. In all my older 2.5 Gen Tundras I used Royal Purple in the rear and Mobil 1 in front and transfer case.
What diff fluid to use for 3rd Gen 2022 and up models in both 4x4 and 2WD models please. Do the 3rd Gen Tundras require friction modifiers? I know the older Tundras didn’t.

 

Hmmm, owners manual by chance?

 

It might be 75W85. 75W90 will work. I plan on using Amsoil Severe Gear.

 

Thank you for specifics. Yes looking for something specific as a brand that someone else has used and prefers. Also how many quarts? Both 4X4 and 2WD take same volume and type in rear diff?

 

Ok, this took me 1 minute to find in owners manual. Your welcome. By the way, if you dont have an OM, you can download it easily & free. Makes it quick & easy to answer many questions.

 

Every 30k miles.

 

Thank you for picture. I have owners manual. I made a quick post as I was wanting more specifics *if everyone still likes to use Royal Purple etc. Things the owners manual isn’t as personable on. Also was hoping that this will help people in the future decide what diff fluid to go with as well as how much and how often change should be done. So they can see it on this forum through a search and save them from having to go outside to their vehicle and thumbing through their owners manual. Still helpful information and I appreciate the info and picture you posted.

Toyota specifies 75W-85 GL-5 which is somewhat hard to find,

$39 75W-90 GL-5 Limited Slip, Ultra Long Drain 500k Miles, Manual Transmission, Gear/Differential Lubricant (1 Gallon)

75W-90 GL-5 will work just fine and is very common in auto parts stores. No friction modifiers are required as 'limited slip" function is carried out electronically by the ABS/traction control system.

 

^^^^ What @Rcflyersd said.

$39 75W-90 GL-5 Limited Slip, Ultra Long Drain 500k Miles, Manual Transmission, Gear/Differential Lubricant (1 Gallon)

75W-90 GL-5. Common in most Auto Parts stores. My Toyota Master Tech who does "work on the side" uses this. You simply pay more for the Mothership product and get zero benefit.

 

I’ve used Amsoil. This truck will get Amsoil. The additive can be added to both locking and non locking diffs with Amsoil already has.

 

I also used

$39 75W-90 GL-5 Limited Slip, Ultra Long Drain 500k Miles, Manual Transmission, Gear/Differential Lubricant (1 Gallon)

75W-90. 75W-85 is very expensive and nearly impossible to go buy off a shelf at your typical auto parts store.

 

use amsoil garage feature and it will set your straight.

 

Amsoil severe gear.

Thank You! This is spot on what I was looking for. The no friction modifiers is a great piece of additional info. Thank you for being specific. I know it will help others in the future that are seeing this too!
