I did mine at 2000,5000 and every 5000 miles thereafter. I come from the old school and just can't stand to let it go 7500-15000.

I think cummins just wants to sell more engines.

Sure, longer service intervals means lower cost of ownership. So for commercial use, it's either an advantage for them or at least keeps things equal with their competitors.

Typically they have research and testing to back up their claims. After all if their motors were to be less reliable then they wouldn't sell em either!
