Years of work are under way to develop two new diesel-engine oil service categories to help hit emission targets and boost engine performance.
Work is starting on developing a new API diesel engine oil category to help meet the demands of upcoming greenhouse gas and fuel mileage regulations.
Diesel engine vehicles can be damaged by using low quality diesel exhaust fluid (DEF). Repairs can be very expensive with long downtime possible, and damage could void the manufacturer’s warranty.
The American Petroleum Institute's new diesel engine oil-service categories, API CK-4 and FA-4, will begin appearing in the marketplace on Dec. 1.
The American Petroleum Institute is introducing a special Service Symbol Donut designed to help buyers differentiate between the new API FA-4 and CK-4 service categories for diesel-engine oils.
