Factory/OEM Lubricant Specs

Hi All,

First post, first Tacoma (2019). I searched the threads before posting and couldn't find any info, sooooo...

Does anyone know what BRAND of gear oil is used at the factory when they fill up the front/rear differentials and gear box? I figured they have their own branded oil, but not sure.

 

Toyota ????

Does it really mater what brand as long as you got the weight right?

PS: WELCOME

 

Yes, to me it does, lol.

Also I assume they are using synthetic gear oils. Eh?

 

Probably have to ask Toyota.

 

Probably something like this:

 

My best guess is Warren makes their non synthetic gear oil. When you go to the dealer it’ll say bulk 75W90 on the receipt.

 

Just get some Redline MT-90 and 75W-85.

 

They use Toyota 75w85 gl5 and fucking unicorn piss SAE 75w for the transfer case that only Toyota makes and the cheapest I found was $53/L at my local dealership. Don't be a dum dum like some people who buy 2 cans because you need 1.1 qt. The cans are Liter cans which are 1.05 qts.
I just did mine and my wife's truck. I used Ravenol 75w85 gl5 for the front and rear and the Toyota unicorn piss for the transfer case. Only reason I did that is because my wife's truck is full time 4wd and calls for it as well.
