Where to Get Gear Oil

Can’t find 75w-85 and 75w at my parts store. I know the Toyota genuine stuff is expensive af. Who you guys buy this stuff from

 

Amsoil

 

Get close to the stock weight, run it.

I'd bet the dealer does the same thing.

 

Just use

$28 75w-90 Synthetic Gear Lube - 1 Quart (Pack of 2)

75w-90 in your favorite flavor from Napa or Walmart. I like the Valvoline squeeze pouches.

T-case either redline, ravenol or the OEM liquid gold

 

75w90 does completely fine and just about every major brand makes that particular weight….go to the part store/walmart and pick your favorite.

Of all the fluids in the truck, it’s going to care the least about what gear oil you put in the diff…and certainly isn’t going to care about 90 weight instead of 85.

 

Severe Gear for the Win!!!!

 

Redline makes it too. You can pick some up on Amazon

$24 Red Line 50104 75W85 GL-5 Full Synthetic Gear Oil for Hypoid Limited Slip Differentials - 1 Quart

https://www.amazon.com/dp/B000J3G8KE. But you can pick up 75w90 way cheaper.

75w also made by Redline (goes by MT-LV)

$22 Red Line 50604 MT-LV 70W/75W GL-4 High-Performance Full Synthetic Gear Oil Lubricant for Manual Transmissions & Transaxles - 1 Quart

https://www.amazon.com/dp/B07V1VW32J and Ravenol https://a.co/d/7ZoyeH9.

 

I used Valvoline 75w-90 fully synthetic in the Diffs and the expensive Toyota fluid in the transfer case. 75w-90 you can find anywhere. Transfer case fluid I bought on Amazon because most other online places wanted to charge shipping.

$98 Toyota Genuine Transfer Case Gear Oil LF 75W 1 Litre 08885-81080

https://www.amazon.com/TOYOTA-Genuine-Transfer-Litre-08885-81080/dp/B086R57CRP

Don’t forget to get gaskets/washers for all of the plugs.

 

That’s exactly what they do, they don’t go to the parts counter for most.

 

I buy the OEM stuff from dealers online. I found a few who always have the stuff on sale. I recently purchased all my OE fluids from Toyota of Colorado Springs.

Just search 08885-02906 for the Diff and 08885-01806 for Transfer

 

ECGS sells and highly recommends 85-140 dyno oil...

Their assemblies are not magically different then OEM...

Run an oil close to spec and don't worry about it. If you want to find some rare expensive oil then go for it...

 

Thanks all got the redline 75w-85 for the diffs. Tcase running the OEM stuff. Redline 75w was GL-4 rated which I believe is incorrect. Going to just bite the bullet and get the OEM stuff for the T-case. Pricey but don’t have to do this often and get the peace of mind

 

Just did the exact same thing on my 21 Tundra.

I ran the Amsoil 75 85 in the front and rear diff … the transfer case did the redline 75w . If I recall it meets standard that is required for the t-case . No need for that Toyota gold
.The amsoil I picked up at my local ford dealer cheap and in stock … the redline I got at Napa was a kinda of hard to get had to wait a couple days to get shipped to store .

 

You don't give specs such as year and miles on your truck.
It's probably worth a lots so why not just spend the few extra and get oem at dealer.
