What is API standard for oil?
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.
What is API CJ?
API Service Category CJ-4 is the primary performance category for high-speed, four-stroke 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.
What does API CJ-4 mean?
API Service Category CJ-4 describes oils for use in high-speed four-stroke cycle diesel engines designed to meet 2007 model year on-highway exhaust emission standards as well as for previous model years. Oil Interchangeability Guidelines and the API Guidelines for SAE Viscosity-Grade Engine Testing.
What’s the difference between CJ-4 and CK 4 oil?
API CK-4 oils will replace current API CJ-4 engine oils and will be backward compatible with most applications where engine manufacturers currently recommend CJ-4. The new CK-4 oils will provide a number of improvements over CJ-4, including improved shear stability, oxidation resistance, and aeration control.
What is API standard for?
American Petroleum Institute (API) standards advocate proven, sound engineering and operating practices and safe, interchangeable equipment and materials from drill bits to environmental protection. API standards allow you to: Improve operational excellence. Ensure compliance and safe practices.
Can I use API SN instead of API SF?
API SN to SJ are for the most recent cars, API SH to SA for the older cars. If you read the table properly, the car needs an API SF. In theory, both SH and SL could be used. As also explained earlier, more modern oils are not necessarily adapted for older engines.
Can I use API SP instead of SJ?
API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.
Can I use regular oil in a diesel engine?
“If the need arises to top off with a different brand, but the same viscosity and API service category, be assured that heavy-duty diesel engine oil brands and base oil types (conventional, synthetic blends or full synthetic) can be mixed without fear.
How do I get an API standard?
Here is how you or your organization can obtain them today:
- Publications Bookstore/Catalog: Purchase single-user copies of individual standards and download the API Publications Catalog.
- Subscription Service: Gain organization-wide access to API Standards with a subscription on API’s standard subscription service.
What is the difference between API and ASME standards?
Another way to perceive this difference is that the ASME standards are the ones to achieve or design towards while the API standards are the recommended practices but that these practices are not legally binding whereas once the pressure system has been ASME certified the ASME certification is legally binding.
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.
What kind of oil is good for CJ-4 engine?
API CK-4 oils exceed the performance criteria of API CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 and can effectively lubricate engines calling for those API Service Categories. When using CK-4 oil with higher than 15 ppm sulfur fuel, consult the engine manufacturer for service interval recommendations.
Can you use API CK-4 oil with API FA 4 oil?
API FA-4 oils are not interchangeable or backward compatible with API CK-4, CJ-4, CI-4 with CI-4 PLUS, CI-4, and CH-4 oils. Refer to engine manufacturer recommendations to determine if API FA-4 oils are suitable for use. API FA-4 oils are not recommended for use with fuels having greater than 15 ppm sulfur.
