Its the ZINC levels and the quality of the zinc in the oil. They want you to use the highest level type/brand. Rotella has been the known to have the best zinc and that's why its been the go to over the past while....

i just picked up my boat from winterization with oil change. the invoice said Rotella 15-40. I questioned them, and stated I thought there was a change from PCM. They said they were not aware of the bulletin.

Should I take the bulletin to them and have them change it or let it slide until next oil change?

Also, is there a PDF version of the bulletin I can print out?

Thanks

It probably won't hurt it, and if it does, they're a dealer, so they should be responsible.

They should certainly be aware of the bulletin. Kinda scary that they aren't.

Yeah, considering 15w40 was go to for...like...ever. You be fine. Not that I have any evidence it matters, but what i try to do is when i use my boat when cold out I let engine warm up extra long to be sure oil is warm and flowing without raising the oil pressure.

P.S. PDF would be nice...

thanks guys, i think i will let it be and have them change it at the beginning of summer. I will point out the bulletin again.

the image posted on this thread is super blurry when printed. can someone post a clear version or the pdf?

thank you

This oil fits the bill. 5w-30 and Dexos certified.

I just put it in my H6 engine this weekend

Since this is an oil thread . Shell recently added a Full Syn 15W40 as well for those that want to go that route. It’s only couple , two , tree bucks more .

That's what I went with this year. There was some discussion as to the rating standard of the not meeting the spec in the manual. I went with it anyway.....

Must be why it is cheap to purchase. LOL

Possibly who knows for sure. I would find it hard to believe that using this oil is going to have a detrimental effect on the engine. Everything in the specs and documentation show nothing but better than the standard with no cautions of using it in any application that the non synthetic versions.

Hope so, just put about 4 hours on my boat with this oil

I jumped from the 15W-40 Rotella in the engine originally (on my third oil change) to Rotella 5W-40 T6 full synthetic. I called PCM to discuss as I did this; while they thought this was overkill to use full syn, they said it was fine to use. I will stay with this oil. I change way in advance of the hours requirement, but not in advance of “120 days” as this bulletin advises. I’ll sleep fine with my plan.
