My pre-emissions engine can go up to 15k or one year depending on use. Oil stays clear without any heavy work. 220k miles. T-6, Baldwin oil & fuel filter. MOPAR deep air filter
These days it really doesn’t matter. Oil is unbelievably good compared to thirty years ago. Just stick with owners manual and be strict about interval.
FAIW, we run the Detroit’s in the fleet to 30k miles. That’s about 2.5-months.
I can go 15k on my 2015 Cummins also but what does your owners manual say?
