API SN PLUS
Amid pressure from original equipment manufacturers (OEMs), the American Petroleum -Institute (API) is Accelerating the release of a supplemental specification to further the address low-speed pre-ignition (LSPI). AMSOIL is ahead of the game with three lines of motor oil that achieved 100 percent protection against LSPI. AMSOIL Signature Series, XL, and OE brands provide 100% protection against LSPI.
OEMs have been turning to smaller, turbocharged, gasoline- direct-injection (T-GDI) engines in recent years to meet increasingly strict fuel-economy and emissions requirements. Although modern T-GDI engines deliver more power while using less fuel and producing fewer harmful emissions than their predecessors, a potentially damaging side effect has emerged: low-speed pre-ignition (LSPI). LSPI is a more destructive form of regular pre-ignition, which has been around as long as the internal- combustion engine. Because motor oil formulation can play a huge role in combating LSPI, the new ILSAC GF-6/API SP motor oil specification are slated to include a test for LSPI. But the introduction of ILSAC GF-6/API SP has suffered delays and won’t take effect until 2019 at the earliest. OEMs, however, can’t wait that long. For that reason, many are pushing hard for an interim specification to measure LSPI protection.
API SN Plus The pressure from OEMs has spurred the API to fast-track API SN Plus and set an optimistic early 2018 release date. This proposed supplemental specification requires motor oil to meet particular benchmarks that reduce the likelihood of LSPI. General Motors’ proprietary dexos1® Gen 2
Specification released in August also requires motor oils to undergo an LSPI test. The SN Plus designation would likely be integrated into the API “donut” and displayed on the back labels of motor oil packaging.
A properly formulated motor oil is critical for protecting an engine against LSPI. As the industry struggles to catch up, we have thoroughly examined the threat LSPI poses and already developed solutions. We’ve developed advanced detergent systems that protect against LSPI and exceed the industry standards. Signature Series, XL and OE achieved 100 percent protection against LSPI1.
You can be confident that AMSOIL synthetic motor oils protect modern T-GDI engines against LSPI and deliver years of reliable service.
If you have a new gasoline car or truck use AMSOIL motor oil to ensure that you will protect your investment with the best motor oils.
