I use a full synthetic oil with an extended life filter, up to 50,000 miles or one year on some engines. I change oil and filter every year on all my vehicles including my Cummins engine truck.
I couldn't drive YOUR truck for 50000 miles on the same oil, I'd never sleep.
Just pull my diesel engine dip stick after one year, my oil is cleaner than any gas engine you've seen, I'm not doing 50,000 ml per year only about 15,000ml but many are with oil analysis. My son took his 2011 ram diesel in for a quick lube oil change on the road, they told him there
was something wrong with his truck, when he asked what the problem was they told him his oil was TOO clean.
