New Symbol for Recently Approved Diesel Engine Oil

The American Petroleum Institute (API) is debuting a special service symbol to help the market 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 symbol features a shaded section to differentiate API FA-4 diesel oils from CK-4 oils. T

Most truck manufacturers recommending API-licensed CJ-4 engine oils will likely recommend API CK-4 oils as soon as they are available.
