Great oil, makes the diesels run a little quieter and can extend oil change interval. Saves money and engine is better protected. Easy choice to have it delivered to your door in cases of three

Excellent oil, one of the best on the market! This product should be stocked on the shelve in every store nation wide. Product did arrive in time promised.

I switched to Rotella 2 years ago and the results are clearly visible. Used in motocross bikes clutches last longer and trans gears show much less wear. Really good product.

Been trying for months to get moreT6. Luckily I had enough for my last oil change but I like keeping it on hand. I can not find why and when the shortage will end. Next change I will be looking for other brands

I have been using Rotella-T6 in the 5W/40 weight in my turbocharged SAABs equipped with the 2.3 liter engine for over 10 years. Used Oil Analysis performed at up to 300K miles show effectively zero engine wear.

I use Rotella T6 in everything. Currently running in my John Deere 180 with a Kawasaki motor, Kubota BX2370 tractor, Ford Explorer 4x4 mud truck, Chevrolet 5.3, and even a 2017 Subaru Legacy! Can't beat the performance.

I buy the 5w-40 at the store, is fantastic oil. I run it in my 1999 Toyota Tacoma, Polaris Ranger and John Deere tractor. All 3 engines run quieter, cool and clean. Amazing oil. I may start running it in my lawnmower and generator as well.

On my second oil change with T6, not sure why Ford doesn't recommend it for their 6.7 diesel motors. The engine absolutely runs quieter than using MotorCraft or T5. Excellent product in my opinion.

Bought my 2011 Ram 3500 Cummins 6.7 in 2012 with 300 test miles on it. Put Shell Rotella T6 in it right away and have run nothing else. Great oil, but hard to find right now.

after researching I went with this because it exceeds the high priced john deere fluid I was using on my JD 5420 4X4.There is a cold winter coming in the Adk.Mts. and I need my equipment to start well.
