I own a 2003 38 Open w/ Cummins 6CTA diamond diesels (450hp) and use Rotella T 15W40. Been using it for more than 15 years and have been quite please with it. Know Cummins recommends either Rotella T or Valvoline Blue...

Another vote for Rotella. That’s what I used when I had gassers and it seemed to do great.
