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.

I USE THIS IN MY 2000 CATERPILLAR 6NZ, AVG ABOUT 5.9 MPG. I ALSO USE THIS IN MY FORD 6.0 POWER STROKE, MY HONDA VTX 1800 STREET BIKE AND KAWASAKI BRUTE FORCE 750 SINCE IT HAS THE JSOMA RATING.

Great oil for almost any engine. I run it in my truck, tractor, motorcycle, lawnmower, and generator. One bottle to fill them all, makes my life easier.

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.

My Prius has over 190,000 miles and recently began to leak a couple quarts of oil between changes using 5w-30. After switching to Rotella 5w-40 the oil consumption has completely stopped, and its still getting nearly 50mpg!

I’ve legit been using this oil in my trucks since 2013 and haven’t touched anything else since. This oil has saved me much money and kept my trucks from being placed out of service due to engine and turbo issues.

Ive been using this oil on my Subaru for over 10years now. Currently mileage @230k miles There has been a shortage recently of T6, And I may need to use an alternative 1/2022

I've been using this Rotella in my caterpillar engine, it has outstanding some other products and help me with cost, since I don't have to change oil as often.

I have been using the Rotella T4 15w40 in my Honda Goldwing GL1100 for a number of years. Smooth transmission and no clutch slip. 82000 miles done and no problems. The T4 along with T6 is JASO MA2 compliant.

Really easy to find at a great price. Awesome rebate. I can run longer oil change intervals. Flows better in my cold climate. Would not use anything else in my duramax. Very happy!
