What type of engine would an oil with the C API grade be used in?
Diesel C Categories. 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.
What is API oil classification?
The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. It specifies the viscosity grade required for your car’s engine.
What are the classification of engine oil?
The 11 viscosity grades are 0W, 5W, 10W, 15W, 20W, 25W, 20, 30, 40, 50, and 60. In the United States, these numbers are often referred to as the “weight” of a motor oil, and single-grade motor oils are often called “straight-weight” oils.
What is C oil?
“C” category oils have been formulated primarily for diesel engines and may not provide all of the performance requirements consistent with vehicle manufacturers’ recommendations for gasoline- fueled engines.
Is API SN better than SL?
As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.
What are API service classifications?
Can you use API SN instead of SL?
For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible. API SN to SJ are for the most recent cars, API SH to SA for the older cars.
What is API SN?
What is “API SN PLUS”? API SN PLUS is a new motor oil specification developed for turbocharged engines that is being developed in response to automakers request for motor oils that protect against Low-Speed Pre-Ignition (LSPI).
What does API stand for in oil classification?
API Classifications. API Oil Service Categories. The API Engine Oil Licensing and Certification System provides a simple designation of letters and numbers that allows engine manufacturers and oil marketers to clearly provide users with the information they need to ensure that the proper oil is selected for an engine.
When to use API lubricant for diesel engines?
Oils designed for this service may also be used when API Service Category CD is recommended. Service typical of two-stroke cycle diesel engines requiring highly effective control of wear and deposits. Oils designed for this service also meet all performance requirements of API Service Category CD.
What are the different types of oil classifications?
Each letter/number designation identifies a service category (e.g., CI-4) which is linked to a series of tests that the oil must pass before it is allowed to carry that designation. The API “S” series describes oil standards primarily for gasoline engines while the API “C” series describes oil standards for diesel engine service.
Which is the best oil to lubricate an engine?
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.
Which is oil is right for You, API or CI-4?
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.
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.
Which is the newest classification for API lubricants?
On November 9, 2017, the API Lubricants Standards Group approved the adoption of SN PLUS, a new classification that may be used in conjunction with API SN and API SN with Resource Conserving. The user language and requirements for the new classification may be downloaded from the EOLCS documents section.
Why do we need API engine oil lubricant?
It was developed in accordance with OEMs request for motor oils that can protect from the potentially catastrophic effects of Low-Speed Pre-Ignition (also known as LSPI, more info here ).
