Lucas Oil 10123 Synthetic SAE 75W-140 Gear Oil - 5 Gallon

I’ve been buying Lucas products for years and believe it makes my vehicles work better. I put this fluid in my rear end and so far it’s working great. Time will definitely tell the true story!

Reasonably priced for the viscosity. Difficult if not impossible to find gallon jugs in any store. Nice that it has the friction modifier in it already as most Lucas products do. I run this or 75/90 in my Jeep TJ and 3rd gen Tacoma without issues.

Put in my 10.5 Sterling! I used a 1 gallon hand pump to fill! It did make the ring and pinion quieter! Good stuff

Very happy with product

expensive but worth it to give my differential better traction

Used this three times for my annual maintenance on our '17 Ram 2500 Cummins. We tow an average of 5000 miles with an 8500lb trailer in the intermountain west, annual miles on the truck are about 15k. Each year the oil is still close to it's original color. Buying a gallon is perfect for the AAM 11.5 axle capacity too.

I used this to change me rear differential fluid in my 2014 Nissan Frontier PRO4x.I was not expecting to notice any difference, after all , it's just a fluid change. Though very minor, I did notice it seams to be just a little bit quieter going down the road. The one gallon jug was difficult at best, to gent into a position to refill the differential, but not impossible.

Nice stuff, get a bottle pump to put in rear diff
