API SN PLUS

Everything you need to know about API SN PLUS

TOTAL QUARTZ to Meet API SN PLUS Specs

The new API SN Plus specification was created to quickly combat issues that come with newer TGDI engines and Low-Speed Pre-Ignition (LSPI) concerns. This new category is fully backwards compatible with API SN, because the “Plus” adds additional testing for the LSPI problem. The planned release date for this new specification is May 1, 2018.

WHAT IS LOW-SPEED PRE-IGNITION (LSPI)?

LSPI is an event that happens in the combustion chamber of TGDI engines at low speeds and high loads. The fuel/air mixture spontaneously combusts prematurely before spark timing, causing a “super-knock” in the combustion cylinder. If left unchecked, this event can cause damage to engine parts, and potentially catastrophic engine failure in severe cases. Since 25% of new cars in the United States have TGDI engines, this is an issue that needs to be addressed.

HOW CAN LSPI PROBLEMS BE SOLVED?

Unfortunately there is not one root cause of LSPI, but research indicates that the lubricants used can play a role in combatting this issue. Calcium containing additives are strongly associated with LSPI, therefore a fundamental change in additive technology can mitigate LSPI. API SN Plus is only the first step in this battle with LSPI, with more formulary changes to be addressed with the upcoming ILSAC GF-6 category.

WHICH TOTAL PRODUCTS WILL MEET API SN PLUS?

Total is prepared to meet the new API SN Plus specs beginning May 1, 2018. Labels on packaged products will be updated after the first licensing date of May 1, so please expect a slight delay in seeing the new API Donut on the bottles. The following TOTAL QUARTZ products will claim the new API SN Plus specification.
