75W90 Synthetic Gear Oil with Limited Slip Differential Additive (3 Quart Pack, 75W-90)

You will know if you ever have a leak because of the blue color. Time will tell on how good it is. Can't rate performance until it has been used for many miles. Should be fine, developed in NASCAR country. If not, they won't survive there.

The product was delivered fast. Re4placement of the oil inside the differential was fast and painless. The product was able to reduce noise and transmission to run 12°F cooler.I will see how it will perform but presently I am extremely happy with the product and will purchase again!

Used on rear differential on my 2017 jeep Renegàde. I love the way this lube sticks to the ring and pinion. Not sure of long term use yet

Product works good. I used it in the rear differential on my utv. It does have wet brakes it does quiet the straight cut gear noise. I will buy again.

Interesting intense blue color. Made shifting easier, less clunk going into first, also finding neutral is way easier.

This Gear Oil Reduces Friction Like No Other. This means better fuel Economy and POWER . Research this for yourself.

Seems more hype than anything. I replaced my Explorers PTU fluid with this stuff and can't see a noticeable difference, other than it has a heavy blue dye to it. I think its just a gimmick. Other than that, it seems weighted correctly and works as well as any off the shelve 75w-140. Is it worth the price difference? No, not at all in my opinion.

The product works great with Saab 9-3!
