Hello, We have a 2018 RAM 2500, 6.7 stock not deleted with limit slip rear diff. 55K miles tow a 35 foot fifth wheel about 25 % of the time. I’m changing the rear diff oil. Question, RAM recommends SAE 75W-85 what would you recommend and why? Actually switching to all your oils/fluids, how about engine oil, transmission fluid, transfer case oil and coolant recommendations? Thanks much, Happy New Year!

Our 80w110 S11 gear oil would be ideal for your truck; for the engine run our Blue Diamond series 15w40 oil, and our atf+4 for the transmission assuming it is an automatic. Thanks!

I do believe that this was a contributing factor in the mpg gain that I recently noted. I switched to this gear oil in September (and about 15k miles ago) and there is a huge difference in how freely the truck moves

I have a 2013 Ram 2500 deleted and I use it as a daily driver. It’s still on the stock delete tune and I don’t tow much at all. What’s the best weight for me to get that will help in all seasons? Thanks!!!

Recently ordered the Blue Diamond 85W-140 gear oil on my Ford F250 with a Sterling 10.5 limited slip differential. Will I need to add the Ford XL3 friction modifier additive for this limited slip differential? BTW, love all the Hot Shot Secret products. Have been using them for years.

Yes, we still advise using any factory-recommended limited-slip additives, even with our gear oil… thanks!
