Good product
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!

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

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.
