Thank you for reiterating that logic. You are correct in your analysis. Another thing that may play into it is that some boutique oil companies look at the lack of certifications or approvals as a badge of honor. I think this was more "impressive" back years ago when API was the primary licensing available off the shelf.

And if they did the tests, then it's just a matter of submitting the data with a small payment to get their oil JASO certified. Yet they don't ... there has to be a reason why.
