All I run is amsoil just got a 2 year supply delivered. I can confirm that the engine runs better with it but that's based solely on my perception

Most all of the front line synthetic oils have met the SN+ requirements for several years. Just because you aren't seeing the SN+ on the bottle yet does not mean it isn't compliant.
