WHICH OIL IS RIGHT FOR YOU?

ILSAC STANDARD FOR PASSENGER CAR ENGINE OILS

NAME STATUS SERVICE
GF-6 LATEST Introduced in May 2020 GF-6 is the newest ILSAC engine oil performance standard aimed at improving fuel economy and enhancing engine
capabilities for passenger cars. This new standard will replace the current ILSAC GF-5 standard. ILSAC GF-6A is backwards compatible with
current engines requiring GF-5. ILSAC GF-6B can only be claimed in SAE 0W-16 viscosity grade oils and will only be suitable for engines designed
for this grade.
GF-5 CURRENT Introduced in October 2010 for 2011 and older vehicles, designed to provide improved high temperature deposit protection for
pistons and turbochargers, more stringent sludge control, improved fuel economy, enhanced emission control system compatibility,
seal compatibility, and protection of engines operating on ethanol-containing fuels up to E85.
GF-4 OBSOLETE Valid until September 30, 2011. Use GF-5 where GF-4 is recommended.

NAME STATUS SERVICE
SP LATEST Introduced in May 2020 to address timing chain protection, LSPI protection, wear protection and deposit formation. It is fully backwards
compatible with previous API specifcations that include SN Plus, SN, SM and SL. API SP is the foundation for the ILSAC GF-6 specifcation but
does not include fuel economy. API SP is available for different viscosity grades
SN CURRENT Introduced in October 2010 for 2011 and older vehicles, designed to provide improved high temperature deposit protection for pistons, more
stringent sludge control, and seal compatibility. API SN with Resource Conserving matches ILSAC GF-5 by combining API SN performance with
improved fuel economy, turbocharger protection, emission control system compatibility, and protection of engines operating on
ethanol-containing fuels up to E85.
SM CURRENT For 2010 and older automotive engines.
SL CURRENT For 2004 and older automotive engines.
SJ CURRENT For 2001 and older automotive engines.

DIESEL ENGINES (FOLLOW YOUR VEHICLE MANUFACTURER’S RECOMMENDATION ON OIL PERFORMACE LEVEL)

NAME STATUS SERVICE
FA-4 CURRENT API Service Category FA-4 describes certain XW-30 oils specifcally 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. These oils are formulated for use in on-highway
applications with diesel fuel sulphur content up to 15 ppm (0.0015% by weight). Refer to individual engine manufacturer recommendations
regarding compatibility with API FA-4 oils. These oils are blended to a high temperature high shear (HTHS) viscosity range of 2.9cP–3.2cP to
assist in reducing GHG emissions. . 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. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use.
CK-4 CURRENT API 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. These oils are formulated for
use in all applications with diesel fuels ranging in sulphur content up to 500 ppm (0.05% by weight). However, the use of these oils with
greater than 15 ppm (0.0015% by weight) sulphur fuel may impact exhaust aftertreatment system durability and/or oil drain interval.
CJ-4 CURRENT For high-speed four-stroke cycle diesel engines designed to meed 2010 model year on-highway and Tier 4 non-road exhaust emission
standards as well as for previous model year diesel engines. These oils are formulated for use in all applications with diesel fuels ranging in
sulfur content up to 500 ppm (0.05% by weight). However, the use of these oils with greater than 15 ppm (0.0015% by weight) sulfur fuel may
impact exhaust after treatment system durability and/or drain interval. CJ-4 oils are especially effective at sustaining emission control system
durability where particulate flters and other advanced after treatment systems are used. Optimum protection is provided for control of
catalyst poisoning, particulate flter blocking, engine wear, piston deposits, low and hight-temerature stability, soot handling properties,
oxidative thickening, foaming, and viscosity loss due to shear. API CJ-4 oils exceed the performance criteria of API CI-4 with CI-4 PLUS,
CI-4, CH-4, CG-4, and CF-4, and can effectively lubricate engines calling for those API Service Categories. When using CJ-4 oil with higher
than 15 ppm sulfur fuel, consult the engine manufacturer for service interval.
CI-4 CURRENT Introduced in 2002. For high-speed, four-stroke engines designed to meet 2004 exhaust emission standards implemented in 2002. CI-4 oils
are formulated to sustain engine durability where exhaust gas recirculation (EGR) is sued and are intended for use with diesel fuels ranging in
sultur content up to 0.5% weight. Can be used in place of CD, CE, CF-4, CG-4, and CH-4 oils. Some CI-4 oils may also qualify for the CI-4
PLUS designation.
CH-4 CURRENT Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards CH-4 oils are specifcally
compounded for use with diesel fuels ranging in sulfur content up to 0.5% weight. Can be used in place of CD, CE, CF-4 and CG-4oils.
CF-4 OBSOLETE Introduced in 1990. For high-speed, four-stroke, naturally aspirated and turbocharged englnes. Can be used in place of CD and CE oils
CG-4 OBSOLETE Introduced in 1995. For severe duty, high-speed, four-stroke engines using fuel with less than 0.5% weight sulfur. CG-4 oils are required for
engines meeting 1994 emission standards. Can be used in place of CD, CE and CF-4 oils.
