Rotella T T6 Full synthetic oil. 5-40
Using in my eco diesel as a replacement to a lighter euro oil. Exceeds the requirements shown for the Rocket.
Turbocharged engines, with their higher temperature operating ranges and extreme heat turbochargers demand a high quality oil. Rotella is easy to find.
I run regular Rotella conventional oil in my Cummins and in my two Kubotas. Probably switch to the T6 oil.
