Q: When will CK-4 and FA-4 engine oils be made available?

A: Oil companies, additive technology providers, and the engine builders have been working for over five years to ensure that these new products meet the needs of the next generation of diesel engine technology, while also being suitable for use in the engines on the road today. The standards are now fully approved and American Petroleum Institute (API) will allow products that meet these new specs to be “licensed” starting on Dec. 1, 2016. You can expect to see the new products in the market very soon after that date!
