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

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.

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.

My duramax and I have been extremely happy with T-6. Starts great in winter, even when -30. Made mistake of using oil a friend gave to me, truck didn't like it when temps went below freezing, started hard. Won't deviate again.

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.

Iv ran a few different oils in my race bikes and ever since the switch from A recommendation from my father that has a gold wing with 90,000 miles no issues my race engines show very very minimal wear and tear in between seasons

When your running a 7.3 powerstroke good oil is a must. This oil has my truck purring line a kitten. Much easier engine starts even in the heart of winter.

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.

This is my go to oil for everything besides my daily driver. I use it on my motorcycle, ATV, and lawn tractor. Great product and generally the price is reasonable.

Ordered online and was delivered to house. This Synthetic oil good for Ram Eco diesel; one 3 gallon case is just a bit more than required for an oil change. I've used other Rotella in my other diesel engines.
