NEW NORTH AMERICAN REGULATIONS

Experts from the National Highway Traffic Safety Administration (NHTSA), the American Petroleum Institute (API) and the Environmental Protection Agency (EPA) have set more rigorous greenhouse gas (GHG) emissions regulations prompting engine manufacturers to make cleaner and more fuel efficient diesel engines. Oil manufacturers are faced with the opportunity to produce new and more advanced oil technology for these new engines. Major North American OEMs are also expected to improvement in oil oxidation control, aeration control and shear stability.

INTRODUCING PROPOSED CATEGORY 11 (PC-11)

The next generation of heavy duty engine oils (HDEO) is right around the corner. Proposed Category 11, known by its short name, PC-11, is establishing new industry standards to deliver significant improvements in engine protection and fuel economy. On December 1, 2016, the new diesel engine oil specification is expected to take in effect under two categories: API CK-4 and FA-4. Intended to surpass the current CJ-4 oils in fuel economy, this new API category of oils are currently being referred to as PC-11A and PC-11B.

In addition to a better fuel economy, both oils will also deliver superior performance over the current oils. Although, the former, CJ-4, will continue to protect new and older engine models. Engines manufactured after January 2017 will begin to take advantage of the benefits of these improvements.

Although engine and oil technology has continued to improve over time, the introduction of the new PC-11 engine oil performance category will result in the largest and most impactful change in oil specifications that the industry has seen in a decades. These two new categories are derived from years of collaboration between the oil and additive industries and diesel engine manufacturers. One notable difference about the development is API’s introduction of two diesel engine oil standards at the same time.
