Diesel Engines

CI-4
Introduction 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 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 CG-4, and CH-4 oils may also qualify for the CI-4 PLUS Designation.
CH-4
Introduced in 1998. For high-speed, four-stroke engines designed to meet 1998 exhaust emission standards. CH-4 oils are specifically 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.
CH-4
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 stands. Can be used in place of CD, CE, and CF-4 oils.
CF-4
Introduced in 1990. For high-speed, four-stroke, naturally aspirated and turbocharged engines. Can be used in place of CD and CF oils.
CF-2
Introduced in 1994. For severe duty, two-stroke cycle engines. Can be used in place of CD-II oils.
CF
Introduced in 1994. For off-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
Introduced in 1985. For high-speed, four-stroke, naturally aspirated and turbocharged engines. Can be used in place of CC and CD oils.
CD-II
Introduced in 1985. For two-stroke cycle engines.
CD
Introduced in 1955. For certain naturally aspirated and turbocharged engines.
CC
CAUTION- Not suitable for use in diesel-powered engines built after 1990.
CB
CAUTION- Not suitable for use in diesel-powered engines built after 1961.
CA
CAUTION- Not suitable for use in diesel-powered engines built after 1959.
