What Does CK-4 Mean in Oil?
API CK 4 synthetic engine oils will replace CJ-4 engine oils and will be backward compatible with most applications where CJ-4 is currently recommended by engine manufacturers. Improved shear stability, oxidation resistance, and aeration control will be among the benefits of the new CK-4 oils over CJ-4.
Just because the API establishes a standard doesn't mean that all oil brands are created equal. Some people will regard the standard as a minimum that must be met. Others will see it as a place to start when developing a better offering. It is advisable to go for 10W30 CK 4 synthetic engine oil for the best performance.
Choose DOXA10W30 CK 4 Synthetic Engine Oil
When it comes to choose which brand to utilize in your business's equipment, it makes sense to choose brands that meet industry standards. If you already have a trusted brand, such as DOXA 10W30 CK 4 synthetic engine oil, there's no reason not to stick with it. When deciding between CK4 and CJ4, though, it may be a good idea to examine alternative oils with good reputations that you haven't tried previously.
FA-4 oils will provide similar benefits to CJ-4 oils, although it's worth noting that FA-4 oils are only for use in modern on-highway diesel engines. Where engine manufacturers recommend CJ-4, FA-4 oils will have limited or no backward compatibility with on- and off-highway diesel engines.
Updated service categories for diesel oil were required as vehicle manufacturers strived to produce harder, more fuel-efficient engines that emit fewer emissions than ever before. In comparison to older vehicles, newer semi engines are designed to run constantly and at higher internal temperatures.
Engines are also smaller, with enhanced start/stop technology and combustion design, as well as variable valve timing. There are two new categories for heavy duty engine oils in the revised standards: CK4 and FA4. Although both oil classifications are similar, the differences are significant enough that you should be aware of them.
Let’s Have a Look at the Differences Between CK4 and CJ4
You don't need to know much about chemistry to appreciate the advantages of 10W30 CK 4 synthetic engine oil over CJ4. The new oils have improved oxidative stability, resistance to aeration, and shear stability. In fact, lubricants must pass two new tests in order to fulfil the CK4 oil API standards: the CAT Aeration test and the Mack T13 test.
Furthermore, CK4 synthetic engine oils offer superior engine protection than CJ4 oils. Because of the lower viscosity classes, using CK4 should extend the duration between oil changes and improve fuel economy. You'll see familiar, frequent grades like:
Suggestions for Choosing the Right Brand for CK4 Synthetic Engine Oil
If you're going to shop for brands, learn to read labels. In addition to the API-required trials, see if the brand has conducted its own testing. Word of mouth is also quite significant. Inquire with heavy-duty mechanics about the products they use and why they suggest them. In this respect, DOXA full synthetic lubricants for heavy duty vehicles qualify every standard.
