Okay, two things worth mentioning since Amsoil was brought up:
The lawsuit is in direct relation to the use of FALSE API logos, not just a 'claim' to meet or exceed API standards.
SSO is boutique. XL, OE etc...are not all formulated like the SSO lineup. Especially OE. So, if it's a debate about whether Amsoil is 'over dosing' beyond API specs, it's probably only with their high-end oils.
I have yet to see evidence that shows API-SN with it's generally low cal/higher mag content is even on par with API-SM standards. That is actually one of those grey areas. Is the new standards the best just because it says it's the best? Well, then define best. Again, another debate.
