Information:
The current API categories represent the minimum requirements for diesel engine oils. These categories are developed in collaboration of OEMs and the Oil and Chemical industries.The current licensed oils are:
API CK-4, released December 2016
API CJ-4, released 2006
API CI-4, API CI-4PLUS released 2002
API CH-4, released 1998Each API category is technically more advanced and of higher performance than the prior one.Refer to API 1509 document and/or ASTM D4485 for details of the API tests requirements and limits.Note: Obsolete API oil categories are not licensed by the API and hence are of uncontrolled quality. These oils are technically inferior to current oils and can result in reduced engine performance and life. These obsolete oil categories are not allowed in Cat engines.API FA-4 is NOT recommended for Caterpillar engines. API FA oil is designed with low High Temperature High Shear (HTHS) viscosity oil for use in certain 2017 On-Highway truck engines that have to meet certain on-road emissions regulations. This category is not backwards compatible.In order to help protect your engine, and in order to help optimize oil drain intervals for engine applications and duty cycles, use Cat S O S Services oil analysis. Refer to the section below and to the section on Cat S O S Services given later in the Special Publication.
Depending on application severity and localized environmental conditions, and also depending on maintenance practices, operating Direct Injection (DI) diesel engines and operating PC (Precombustion Chamber) diesel engines on fuel with sulfur levels over 0.1 percent (1000 ppm) may require significantly shortened oil change intervals in order to help maintain adequate wear protection. Refer to this Special Publication, "Fuel Specifications" section, “Diesel Fuel Sulfur” topic for additional information.
Fuel Sulfur Impact on Engine Oil
The use of Cat S O S Services oil analysis is recommended for determining oil life.For Caterpillar machines operating under emissions regulations such as US EPA Tier4, EU Stage V or other emission regulations controls, the maximum fuel sulfur level permitted by regulations in the US is 0.0015% or 15 ppm. Maximum permitted fuel sulfur levels in other emissions regulated countries may vary from .0015% or 15 ppm slightly and must be followed.In order to help protect your engine and optimize oil drain intervals for engine applications and duty cycles, it is important to use SOS Services oil analysis to determine if the sulfur has degraded the oil. Use Cat S O S Services oil analysis per the following general guidelines:
Recommended normally
For fuel sulfur level up to 0.05 percent (500 ppm), no additional sampling is required. Follow the recommended oil sampling in the machine OMM
For fuel sulfur level of > 0.05 percent to 0.5 percent (500 ppm to 5000 ppm), SOS services oil analysis is strongly recommended to determine oil drain intervals. Sample the oil every 250 hours until a trend is established,
