Product worked great for my 2005 Toyota Tundra limited slip rear diff. I added one bottle of FORD Motorcraft friction modifier and it is performing flawlessly. I am also able to use the same 75W-90 in my transfer case and front diff. I needed 6qts total for all 3 items. I purchased two 1 gallon jugs for a total of 8qts. Free shipping and cheaper than others. I will either purchase 1 gallon next time for my total of 6 qts required or even purchase a bigger bulk order as I will need it anyways.

Good gear oil, differential runs a lot cooler. Cheaper by the gallon.

Excellent gear oil that holds up really well under harsh conditions.
This is my first time using Lucas Oil Synthetic Gear Oil. It pours way faster than any 70W-90 gear oil I have used. Meaning it was way faster to get 1 gallon into me diff. Right away the helical gear whine was gone!I bought other brands of 75W-90 gear oil and tried them to see if gear noise could be lessened.This was by far the best product and quietest my diff. has been. Running an Eaton Tru-Track in my 8.5”. One wheely-pealys’ are no more and the ring gear whine is barely noticeable.
I have about 100 laps on this oil (circle track) and so far it appears perfectly stable running it in a 9 inch ford with a .633 gear at 7200 pinion RPM peak every lap.
The advertisement shows a case/4 for $50.99 reduced from $83.99 yet you only get 1 gallon for $50.99 will return and buy at Freightliner in dallas cheaper
Like the gallon size. Shipped really fast. I trust Lucas Oil Products.
Thick gold. For such an nfrequent change, use good lube.
I've used many lucas products before and they've always worked great for me, especially the upper cylinder lubricant. They say this 75w90 is good for limited slip and hypoid gears which perfect for my 2004 silverado which is a hybrid of both locked and limited slip. No additives needed.
