Lucas has always been a great brand. My differential calls for 75W-140 gear oil. I’m happy that Lucas offers it.

Worth your time
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.

Needed a replacement for the old fluid in the rear axle of my 2000 f350. This was priced well and the synthetic is a requirement for these axles (especially up here when it gets to -40). Didn't need to use any additive...the limited slip seems to be working fine as it is.
