Updated - Ford Super Duty Diesel Motor Oil | Ford Tech Talk

In late 2016, a new specification of diesel motor oil, API CK-4, became available. Following extensive testing, Ford concluded that some CK-4 motor oils could potentially lead to high-mileage engine wear in Ford diesel engines. In response, Ford developed its own specification of diesel motor oil – WSS-M2C171-F1. This new specification of diesel motor oil has been designed for use in all Ford diesel engines and is available now. Motorcraft offers this new oil in 5W-40, 10W-30 and 15W-40 viscosities. To help protect your Ford Super Duty diesel engine and your warranty, remember to look for the WSS-M2C171-F1 specification on the bottle. For other diesel engines, such as the 3.0L diesel in the F-150, refer to our Tech Talk video on Motorcraft FA-4 diesel motor oi.
