CI-4 - Introduced in 2002. For high-speed.

Four-stroke engines designed to meet 2004 exhautsemission standards implemented in 2002. CI-4 oils are formulated to sustain engine durability where exhaust gas recirculation (EGR) is used: 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 for CH-4 oils. Some CI-4 oils may also qualify for the CI-4 PLUS designation.

 

CH-4 - For 1998 Service Duty Diesel Engine Service.

API Service Category CH-4 describes oils for use in high-speed, four-stroke diesel engines designed to meet 1998 exhaust emissions standards as well as for previous model years. CH-4 oils are specifically compounded for use with diesel fuels ranging insulfur content up to 0.5 percent weight.

 

These oils are especially effective to sustain engine durability even under adverse applications that may stress wear control, high temperature stability, and soot handling properties. In addition, optimum protection is provided against nonĀ¬ferrous corrosion, oxidative and insoluble thickening, foaming, and viscosity loss due to shear. These oils also have the performance capability to afford a more flexible approach to oil drain intervals in accordance with the recommendations of the individual engine builders for their specificengines. CH-4 oils are superior in performance to those meeting API CF-4 and API CG-4 and can effectively lubricate engines calling for those API Service Categories.

 

CG-4 - For Severe Duty Diesel Engine Service.

API Service Category CG-4 describes oils for use in high speed four stroke-cycle diesel engines used on both heavy-duty on -highway (less than 0.05% wt. sulfur fuel) and off highway (less than 0.5% wt. sulfur fuel) applications. CG-4 oils provide effective control over high temperature piston deposits, wear, corrosion, foaming, and oxidation stability and soot accumulation. These oils are especially effective in engines designed to meet 1994 exhaust emission standards and may also be used in engines requiring API Service Categories CD, CE and CF04. Oils designated for this service have been in existence since 1994.

 

CF-2 - For Two-Stroke Cycle Diesel Engine Service.

API Service category CF-2 denotes service typical of two-stroke cycle engines requiring high effective control over cylinder and ring-face scuffing and deposits. Oils designated for this service have been in existence since 1994 and may also be used when API Service Category CD-I I is recommended. These oils do not necessarily meet the requirements of CF or CF-4 unless passing test requirements for these categories.

 

CF - For Indirect Injected Diesel Engine Service.

API Service Category CF denotes service typical of indirect injected diesel engines, and other diesel engines which use a broad range of fuel types including those using fuel with higher sulfur content, for example, over 0.5% wt. Effective control of piston deposits, wear and copper - containing bearing corrosion is essential for these engines which may be naturally aspirated, turbocharged or supercharged. Oils designated for this service have been in existence since 1994. Oils designed for this service may also be used when API service category CD is recommended.

 

CF-4 - For High Performance Diesel Engine Service.

This category was adopted in 1990 and describes oils for use in high speed, four-stroke diesel engines, API CF-4 oils exceed the requirements of the CE category, providing improved control of oil consumption and piston deposits.

 

Oils meeting the performance requirements in the following diesel and gasoline engine tests:

The 1 K diesel engine test, which has been correlated with direct injection engines used in heavy-duty service prior to 1990, particularly with regard to piston and ring groove deposits.

The T-6, T-7, NTC 400 and L-38 engines: See API CE Category above for explanation.

 

CE - For High Performance Diesel Engine Service.

Service typical of many turbocharged or supercharged high performance diesel engines, operated under both low speed-high load and high speed-high load conditions. Oils designed for this service have been available since 1984 and provide improved control of oil consumption, oil thickening and piston assembly deposits and wear relative to the performance potential offered by oils designed for Category CD Service.

 

Oils meeting the performance requirements of the following diesel and gasoline engine tests; The 1 G2 diesel engine test has been correlated with indirect injection engines used in heavy-duty service, particularly with regard to piston and ring groove deposits. The T-6, T-7 and NTC-400 are direct injection diesel engine tests. The T-6 has been correlated with vehicles equipped with engines used in high-speed operation prior to 1980, particularly with regard to deposits, oil consumption and wear. The T-7 test has been correlated with vehicles equipped with engines used in lugging operation prior to 1984, particularly with regard to oil thickening. The NTC-400 diesel 211 engine test has been correlated with vehicles equipped with engines in highway operation prior to 1983, particularly with regard to oil consumption, deposits and wear. The L-38 gasoline engine test requirement provides a measurement of copper-lead bearing weight loss under high-temperature operating conditions.

 

CD11 - For Severe Duty 2-Stroke Diesel Engine Service.

Service typical of 2-stroke cycled engines requiring highly efficient control over wear and deposits. Oils designed for this service also meet the performance requirements of API service category CD. Oils meeting the performance requirements measured in the following diesel and gasoline engine tests: The 1-G2 diesel engine test has been correlated with indirect injection engines used in heavy-duty operation, particularly with regard to piston and ring groove deposits. The 6V-53T diesel engine test has been correlated with vehicles equipped with two-stroke cycle diesel engines in high-speed operation prior to 1985, particularly with regard to ring and liner distress. The L-38 gasoline engine test requirement provides a measurement of copper-lead bearing weight loss and piston varnish under high-temperature operating conditions.

 

CD - For Severe Duty Diesel Engine Service.

Service typical of certain naturally aspirated, turbocharged or supercharged diesel engines where highly effective control of wear and deposits in vital, or when using fuels of a wide quality range including high sulfur fuels. Oils designed for this service were introduced in 1955 and provide protection from bearing corrosion and from high temperature deposits in these diesel engines. Oil meeting the performance requirements measure in the following diesel and gasoline engine tests: The 1-G2 diesel engine test has 210 been correlated with indirect injection engines used in heavy-duty operation, particularly with regard to piston and ring grove deposits. The L-38 gasoline engine test requirement provides a measurement of copper-lead bearing weight loss and piston varnish under high-temperature operating conditions.

 

CC - For Moderate Duty Diesel and Gasoline Engines Service.

Service typical of many naturally aspirated diesel engines operated in moderate to severe-duty service and certain heavy-duty gasoline engines. Oils designed for this service provide protection from high temperature deposits and bearing corrosion and low temperature deposits in gasoline engines. These oils were introduced in 1961.
