I think they want people to use their brand, but Pennzoil has it and has the same ratings suggested by Indmar.

Honestly, Id focus on the correct oil first, then if you find it across multiple brands, go with the one you like the best.

My dealer recommended Quicksilver 25-40 synthetic blend. I emailed Indmar and made sure that was an acceptable oil. I was amazed to get a response within minutes and they said that oil meets all their requirements and it is a good oil. I'm changing mine tomorrow.
