44 | ASP June 2016 Technical Category Status Service CJ-4 Current For high-speed four-stroke cycle diesel engines designed to meet 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 efective 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 high-temperature stabil- ity, 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 efectively 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 for- mulated to sustain engine durability where exhaust gas recirculation (EGR) is used and are intended for use with diesel fuels ranging in sulfur 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-4 oils. CG-4 Obsolete 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. CF-4 Obsolete OBSOLETE: Introduced in 1990. For high-speed, four-stroke, naturally aspi- rated and turbocharged engines. Can be used in place of CD and CE oils. CF-2 Obsolete OBSOLETE: Introduced in 1994. For severe duty, two-stroke-cycle engines. Can be used in place of CD-II oils. CF Obsolete OBSOLETE: Introduced in 1994. For of-road, indirect-injected and other diesel engines including those using fuel with over 0.5% weight sulfur. Can be used in place of CD oils. CE Obsolete CAUTION: Not suitable for use in most diesel-powered automotive engines built after 1994. CD-II Obsolete CAUTION: Not suitable for use in most diesel-powered automotive engines built after 1994.
