American Petroleum Institute - API. Maintaining standards whether an oil is suitable for gasoline or diesel engines. The API SN rating is equivalent to the new GF-5 oil rating by the International Lubricant The previous API service category rating for gasoline engines was SM, Motor oil, engine oil, or engine lubricant is any of various substances comprising base oils Current API service categories include SN, SM, SL and SJ for gasoline engines. All earlier service categories are obsolete. Motorcycle oils commonly use in a wide range of Motorcycles; Fully Compatible with Wet / Oil Immersed Clutches; Meets JASO MA2 Specifications; Made in the UK API: SJ, SL, SM & SN.

So if you buy an engine oil meeting only API SA, it's an engine oil formulated for use in vehicles built in the 1920s. And SA is not hard to find mixed in with SN on the shelves at c-stores and others. Furthermore, it's also not hard to find SF, SJ and other API Service Categories on the shelves. For example, SM or CF. The higher the letter, the more recent the technology of the oil. For recent oil, the higher specification will supersede the lower letter grade. For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible.

For example, SM or CF. The higher the letter, the more recent the technology of the oil. For recent oil, the higher specification will supersede the lower letter grade. For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible. Marketers with licensed SN PLUS oils may use SN PLUS in the lower half of the API Donut. Oils licensed by API as API SN with SN PLUS and Resource Conserving and ILSAC GF-5 are eligible to display the API Certification Mark Starburst. Oils may have more than one performance level. For automotive gasoline engines, the latest engine oil service category includes the performance properties of each earlier category. If an automotive owner's manual calls for an API SJ or SL oil, an API SN oil will provide full protection. API SN PLUS is the interim spec within the lubricants industry that supplements the API SN category for gasoline engine oil performance. It helps bridge the gap between current ILSAC GF-5 and future ILSAC GF-6 specifications.
In 2010 the American Petroleum Institute introduced a new engine oil category under the name API SN and a new supplemental category called Resource Conserving. The API SN category is an improvement over the API SM category in the following areas: High temperature deposit protection for pistons. Better sludge control. Introduced on 30 November 2004. Category SM oils are designed to provide improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil. Some SM oils may also meet the latest ILSAC specification and/or qualify as Energy Conserving. So, even for flat tappets, SM or SN oils in xw-20 or xw-30 could still be okay. Some people and manufacturers just want more ZDDP than API SM or SN will allow in an xw-20 or xw-30, which is why they look for API SL. But API SL alone doesn't guarantee more ZDDP. The answer is, look for the letters that follow the words "API Service" in the API Donut. If it's not an SN, SM, SL, or SJ, then it's an obsolete oil. And if there is no API Donut on the motor oil label, BEWARE - because there is a chance you could be buying coffee without the donut.
