TriaxDTF-2 Professional 75W-85 GL-5 Full Synthetic Differential & Drivetrain Fluid | Limited Slip Ready | Compatible with BMW, Dodge, Ford, GM, Jeep, Lexus, MB, Nissan & Toyota (1 Quart)

I drive a 2010 Lexus RX 350. It's an AWD SUV. Both the rear differential and the transfer case require the 75W-85, GL-5 gear oil for lubrication. I change the fluids in these two gears at the same time at each sitting as part of my DIY maintenance. I bought this Triax DTF-2, 75W-85 fluid based on good reviews, low price, and attractive-looking packaging. I figured if the company put in a good deal of effort to make their product look good for consumers, they should also be good at making products that are of high grade and good quality. That was why I bought 3 quarts of these.I replaced the old fluids with them in March 2025. Today is July 25, 2025. The car has been driven for exactly 3,000 miles. And I found that both my transfer case and rear differential are holding up well. I would buy more of these fluids in my future oil changes. Thanks to Triax for offering high-quality and reasonably priced gear oils.

This stuff is amazing! It doesn’t taste very good but then again it is designed for mechanical gears. I guess if you asked my differential it would say that it taste amazing. Do differentials have varying opinions based on how fast they are rotating? Just some of life’s off kilter banter going on over here.

Worked as advertised. It says it’s a “lifetime” product so we’ll see. Truck seems to like it.

Good quality fluid

I had to pull out the front differential in my 2018 tundra to remove my steering rack for repair. To make that job easier I decided to drain my front diff and add new oil instead of reusing the old. While I'm no oil expert, this stuff looked good and has worked as it should. About 1k miles now since I used it and about 100 miles of those in 4x4 and I've had no issues. It is less expensive and as good of quality if not better than other options. I'd recommend for any diff work in toyota trucks

Good

Just installed in my Tundra. I bought this based on good reviews and wanting to use the specified 75W85 not 75W90. This was less cost than redline. We will see how it holds up. I will be changing the fluids each 30K as recommended by the manufacturer even though this oil is supposed to never need replacing.
