What does API CJ-4 mean?
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 kind of oil is CJ-4?
Premium API CJ-4 Synthetic 15W-40 Diesel Oil Delivers extraordinary lubrication in diesel engines in commercial, fleet and personal applications. Exceeds modern specs for emission-quality diesel oil.
What does cj4 stand for in oil?
CJ-4 Service Category Description. 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.
What year was CJ-4 engine oil?
2006
This paper reviews the development of this new oil category called API CJ-4, which was introduced in October 2006. This diesel engine oil category is the fi rst in the U.S. which limits the oil’s sulfated ash, phosphorus, and sulfur in order to insure adequate service life of the DPF.
What is API in engine oil?
The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that engine oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards.
What’s the difference between CJ-4 and CK 4 oil?
It is backwards compatible with all your older equipment and trucks. Anything you’ve put CJ-4 oil in will do fine with CK-4 oil. The only difference is the CK-4 oil will protect your engine better and may enable you extend drain intervals past what you had been doing with CJ-4.
Is CK 4 better than CJ4?
Comparing CK4 vs CJ4 Additionally, CK4 oils provide better protection for engines than CJ4 oils. Using CK4 should increase the time between oil changes and improve fuel economy, as well, thanks to lower viscosity grades.
Does CK4 replace CJ4?
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 the difference between full synthetic and synthetic oil?
The difference between synthetic oil and a synthetic blend is that a synthetic blend motor oil uses a mixture of synthetic and conventional base oils for added resistance to oxidation (compared to conventional oil) and provides excellent low-temperature properties.
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.
What is API cj4 oil?
API CJ-4 oils exceed previous performance requirements and are specifically designed to protect emission control systems, help comply with emission standards, reduce engine wear, and control piston deposits and oil consumption.
What is SAE 10W 30 API?
SAE 10W30 API SN/ SM / SL / SF GASOLINE ENGINE OIL is an advanced full synthetic engine oil designed to keep engines running like new by providing exceptional cleaning power, wear protection and overall performance.
What’s the difference between CJ-4 and CK-4 oil?
Is SAE 10w30 the same as 10w30?
You can use 10w30 instead of SAE 30 in your lawn mower if you want. Since 10w30 has the same viscosity grade at operating temperature, you won’t run into any problems by using it instead of SAE 30. Sometimes it is actually a good idea to make this switch. This would be the case for anybody mowing in colder climates.
