Rotella T6 oil

Best way to know for sure is to have an oil analysis done. I'm sure you could easily go to 5000 miles or more depending on how you run it.

I used conventional Rotella in the trucks, at work. Oil samples pulled at 10k. It showed I could extend to 15k. I left oil changes at 10k. Pulled several samples. All said the same. These were some 6.0 Ford but most were 6.6 Chevrolet. Saved thousands of $$.
