Recently hit 30k miles on my 2014 Toyota Tundra CrewCab and wanted to perform the recommended maintenance on my front/rear diffs as well as the transfer case. In my past Toyota’s (all have been 4Runners), I typically used the same gear oil (75w90 synthetic) in the transfer case as I did in the diffs. My original intention was to do the same on my Tundra. However as I was doing some research on the necessary fluid quantity, I discovered that in 2014, Toyota changed suppliers for the transfer case (From a Japanese supplier to Borg-Warner). As a part of that change, the recommended gear oil changed as well. For the transfer case Borg-Warner (and Toyota) specifically call out 75W (not 75w85 or 90). Good thing I researched a bit…I almost screwed up.Unfortunately 1 liter of OEM 75W costs over $54 at my local stealership. Even worse, since I need 1.3 liters for a drain/refill I’m forced to buy 2 liters and let .7 Liter ($38 worth) go unused! No thanks.Fortunately more online research led me to Ravenol and Amazon. As the front of the bottle states, Ravenol J1C1003 SAE 75W is a fully synthetic direct replacement for the OEM Toyota gear oil (Part # 08885-81081 which in turn is the European part # for the U.S version 08885-81080). Ravenol is FAR more affordable and better yet, it comes with an ingenious built-in fill-spout. Seriously, Mobil1, Royal Purple and other gear-oil suppliers could take a lesson from this container design. Using the built in spout, I was able to fill my X-fer case without spilling a single drop (other than when the fill hole began to weep once it was full). If you have a Toyota and requires 75W and you can’t stomach the price of the OEM – give the Ravenol a try.

First let me say that this type of oil 75w is not really well known since we are used to using a generic 75w90 or 80w90 gear oil for the front and rear differentials and also the transfer case but Toyota changed the manufactured on the transfer case on models 2014 and up tundras from Japanese to a German type. Owners manual says to use 75w only for the transfer case and when I went to my local toyota dealership the techs had no clue…so I noticed the difference when I started using this 75w only oil. The shift is smoother and when switching to 4H is much quieter, I will only use this oil type for my transfer case on my 2014 5.7L Toyota Tundra Platinum.

Kept me from spending big money at the dealership! Very thankful for this find. No issues at all.

So far so good. I put this in the transfer case of my FJ cruiser. I haven’t noticed any differences but I love the caps on these bottles. Every company should do it. I would recommend it just for the cap alone. I will update if any issues occur.

Not sure what was in it before, but it shifts faster in and out of 4×4, no issues so far

2014 4Runner transfer case fluid. This is the correct non-dealer fluid to use.
