A. Yes, they are fully compatible, and there should be no concern if the two are mixed. However, full performance benefits of API CK-4 oils will only be realized when the engine is full transitioned from API CJ-4 to CK-4

...Read the rest of this storyA. Yes. It has become very common for engine makers to issue their own specifications which incorporate requirements from the industry standard along with additional OEM-specific requirements to help customers spec oils that are appropriate for use in their engines. In some cases, this involves using the same performance tests, but with more stringent limits. In other cases, new OEM-specific tests are introduced and required alongside the standard tests. This is particularly true for OEM-specific material compatibility tests and other bench tests that the engine builder has determined to be particularly relevant to their needs. We expect that OEMs will be issuing specifications tied to API CK-4 and/or API FA-4 in the very near future and we will provide updates as they are issued.

In 2010, the U.S. Environmental Protection Agency and National Highway Traffic Safety Administration (NHTSA) announced regulations designed to reduce greenhouse gas (GHG) emissions and mandate fuel economy improvements for medium and heavy-duty engines and vehicles. The new regulations would be phased in between 2014 to 2017, imposing different fuel-efficiency targets based on the size and weight of vehicle/equipment types. Diesel engine design is undergoing a period of significant change to meet the new requirements. The Engine Manufacturers Association (EMA) in turn made a request for the American Petroleum Institute (API) to develop a new commercial engine oil performance category to address engine oil requirements of these new engines.
There are two outgrowths of these new regulations that are driving the formulation of the new oils. For one, the new engine designs run hotter, which puts an increased demand on oil formulas to withstand higher heat environments and actually be able to run longer when exposed to higher temperature. Secondly, it is recognized that engine oil can play a direct role in improving fuel economy, through the use of lower viscosity grades. The EMA request included a proposal to introduce a subcategory with lower viscosity than allowed by previous performance categories.

With improved oxidation stability, wear performance and shear stability, PC-11 oils will deliver additional benefits to customers around engine durability, oil drain interval extension and a wider range of products formulated for a wide range of off-road applications.

Goodyear will announce the 34th Highway Hero Award winner next March during the 2017 Mid-America Trucking Show (MATS) in Louisville, KY.
