Man a ton of swings and misses in this thread.
For an oil to be JASO MA/MA2, it has to “meet” SN spec currently. This happened in May of 2023, with the JASO T903:2023 update.
API won’t give you the shield, because of SP, as previously mentioned. But, there was alot of controversy over the labeling (I sorta mentioned this in the other… rotella thread, the poor response I got from them when I bought this up to them, in writing) - The fact that they are JASO Ma/Ma2 but not SN.
So that’s the driver for the labeling of SN.
