OREANDA-NEWS. The American Petroleum Institute (API) will introduce a special Service Symbol Donut to help consumers identify the recently approved API FA-4 diesel engine oil, which is designed to protect the next generation of diesel engines.  API approved two new diesel oil standards, FA-4 and CK-4, earlier this year.

“API is introducing a diesel engine oil category for use in truck engines designed to meet 2017 model year on-highway greenhouse gas emission standards,” said Kevin Ferrick, senior manager for engine oil licensing. “The FA-4 donut was developed to help truck owners who need FA-4 oils easily recognize the oil and distinguish it from CK-4 oils.”

The new donut, below right, features a shaded section to differentiate API FA-4 diesel oils from CK-4 oils. The API CK-4 Service Symbol Donut, below left, will look the same as the current CJ-4 Donut.                       

Most truck manufacturers currently recommending API-licensed CJ-4 engine oils will likely recommend API CK-4 oils as soon as they are available to better protect today’s diesel engines. API FA-4 oils have been designed to protect diesel engines that are expected to be introduced in 2017. API recommends that technicians and consumers check with the manufacturer of their engine to determine the correct oil to use.

API is the only national trade association representing all facets of the oil and natural gas industry, which supports 9.8 million U.S. jobs and 8 percent of the U.S. economy. API’s more than 650 members include large integrated companies, as well as exploration and production, refining, marketing, pipeline, and marine businesses, and service and supply firms. They provide most of the nation’s energy and are backed by a growing grassroots movement of more than 30 million Americans.
