These oils are formulated for use in all applications with diesel fuels ranging in sulfur content up to 500 ppm (0.05% by weight). For fuels with sulfur content greater than 15 ppm, refer to engine manufacturer recommendations.ĪPI Service Category CK-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway and Tier 4 non-road exhaust emission standards as well as for previous model year diesel engines. API FA-4 oils are not recommended for use with fuels having greater than 15 ppm sulfur. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use. API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 oils. API FA-4 oils are designed to provide enhanced protection against oil oxidation, viscosity loss due to shear, and oil aeration as well as protection against catalyst poisoning, particulate filter blocking, engine wear, piston deposits, degradation of low- and high-temperature properties, and soot-related viscosity increase. These oils are especially effective at sustaining emission control system durability where particulate filters and other advanced aftertreatment systems are used. These oils are blended to a high temperature high shear (HTHS) viscosity range of 2.9cP–3.2cP to assist in reducing GHG emissions. Refer to individual engine manufacturer recommendations regarding compatibility with API FA-4 oils. These oils are formulated for use in on-highway applications with diesel fuel sulfur content up to 15 ppm (0.0015% by weight). Use only when specifically recommended by the manufacturer.ĪPI Service Category FA-4 describes certain XW-30 oils specifically formulated for use in select high-speed four-stroke cycle diesel engines designed to meet 2017 model year on-highway greenhouse gas (GHG) emission standards. Use only when specifically recommended by the manufacturer.įor older engines no performance requirement.

Product Approval Code of Practice and may utilize the API Base Oil Interchange and Viscosity Grade Engine Testing Oils meeting API SH requirements have been tested according to the American Chemistry Council (ACC) Gasoline engines in present and earlier passenger cars, vans, and light trucks operating under manufacturers recommended They may be used where API Service Category SJ and earlier categories are recommended.Ĭategory SJ was adopted in 1996 to describe engine oil first mandated in 1997. Oils meeting API SL requirements have been tested according to the American ChemistryĬouncil (ACC) Product Approval Code of Practice and may utilize the API Base Oil Interchange and Viscosity Grade Engine Present and earlier passenger cars, sports utility vehicles, vans and light trucks operating under vehicle manufacturers It is for use in service typical of gasoline engines in They may be used where API Service Category SJ and SL earlier categoriesĬategory SL was adopted to describe engine oils for use in 2001. Specification and/or qualify as Energy Conserving. Some SM oils may also meet the latest ILSAC Protection, and better low-temperature performance over the life of the oil. API SN with Resource Conservingmatches ILSAC GF-5 by combining API SN performance with improved fuel economy, turbocharger protection, emission control systemcompatibility, and protection of engines operating on ethanol-containing fuels up to E85.Ĭategory SM oils are designed to provide improved oxidation resistance, improved deposit protection, better wear Introduced in October 20 and older vehicles, designed to provide improved high temperature deposit protection for pistons, more stringent sludge control, and seal compatibility. It was developed in accordance with OEMs request for motor oils that can protect from the potentially catastrophic effects of Low-Speed Pre-Ignition (also known as LSPI, more info here).
