May 1 is the first licensable date for API SN PLUS. The soon-to-take-effect specification was requested by the automobile industry to protect passenger vehicles from low-speed pre-ignition (LSPI). We anticipated this change, and the current Signature Series, XL and OE synthetic motor oil formulations all meet or exceed the specification. Look for updated product labels featuring the new API “donut” in the near future. For more information on the dangers of LSPI, visit www.amsoil.com/lspi.
