TRIAX DTF-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.

Awesome product. Hard to find the specific weight differential oil I needed for my Ram 3500 but they had it. At first I had an oh no moment when I saw blue being pumped into the diff, after a little research I found out it is colored that way. I guess it'll make easier to see any leaks that hopefully will never start.

Works great quality product

This fluid looks to be just the ticket for the front and rear diffs on my 2020 Tundra. Exactly the correct weight that the owners manual calls for. This stuff is expensive but looks to be worth it. I change the fluid every 60k miles.

Great product will tell friends

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

Works as advertised, a bit pricey but all oil has gotten high priced .

So far so good.
