    That’s interesting, user friendly. I don’t run at full throttle for long periods and typically run at 75% or so throttle for an hour or less, so I agree the loads probably aren’t a big deal. Our water is only in the 40s or 50s and keeps the engine pretty cold, so I don’t think it would be hot...

    Multiple posters over years on this board have said Yamalube is just an OK oil charging a premium price. I posted a link to one of those threads earlier. If I can get a better oil and pay less, that seems to be a better choice. But some of the posters on this thread thinks there’s a lot of value...

    Thanks guys, I read that paper’s abstract and will check out those links later. The abstract talked about high ZDDP being good to protect boat engines, but bad on car catalytic converters. Like I mentioned earlier, Yamaha still says it is acceptable to use API oils in the engine. If API is OK...

    And I agree, I’m sure I’m overthinking this. But isn’t that the whole point of BITOG, people overthinking oils? 😆

    Thanks for your response, Sir! You answered many of my questions and concerns and led me to more strongly consider sticking to FC-W oils. I’m still interested in any insights people have into why this cert was required and the composition differences, if any, between marine and diesel oils.

    I appreciated Tom’s response, but a bunch of it was a copy-paste from NNMA’s website. And it appears it could be a case of the fox guarding the hen house, although I believe the test is good. If diesel certs don’t have a corrosion test, that’s the first piece of knowledge I’ve learned from any...

    You haven’t contributed anything to a technical discussion. You’ve pointed to a cert a bunch of times, with no info for why it’s good. And you haven’t directly answered the questions I and others have asked you. Here’s one more for you to try: how is the FC-W corrosion test better than the ones...

    Dude, you’re a troll, go away. Or are you on NNMA or Yamaha payroll and it’s your job to obfuscate the issue?

    I hear your logic, Tom. But there are some conflicts of interest that make me hesitate to take their words at face value. NNMA members include the manufacturers who make the oil, these manufacturers pay NNMA the fees to get the cert, and both of them push the oil. None of the FC-W oils seem to...

    Thanks Drew. I mainly operate in saltwater, so corrosion is always a concern. The oil I'm looking at has strong corrosion protection, I think. No one has said otherwise here at least.

    What data do you have to suggest good diesel oils will not? Seems like many oils experts think marine oil is rebranded diesel, and that FC-W cert is a pay-to-play, low bar test.

    Thanks Critic, I have looked at that. Some people think most diesels with decent add packs would pass this test. Do you agree? Or is it impossible to say without putting them through the test?

    Schaeffer product sheet has this level of detail. Mobil 1 FS has a long list of certs and other physical details. Yamalube, a narrative description of how the oil is great. Seems pretty poor given the price they charge. But I guess there are plenty of trusting people out there to buy it.
