ENGINE OIL CAPACITY AND
SPECIFICATION - 6.7L DIESEL
Use oil that meets the definedspecification and viscosity grade.
If you do not use oil that meets the definedspecification and viscosity grade, it couldresult in:
•Component damage that your vehiclewarranty does not cover.
•Longer engine cranking periods.
•Increased emission levels.
•Reduced vehicle performance.
•Reduced fuel economy.
Engine Oil
We recommend Motorcraft motor oil foryour vehicle. If Motorcraft motor oil is notavailable, use motor oil of therecommended viscosity grade that meetsour specification WSS-M2C171-F1. You canfind the list of approved motor oils atwww.motorcraft.com.
Do not use supplemental engine oiladditives because they are unnecessaryand could lead to engine damage that yourvehicle warranty does not cover.
The use of correct oil viscosities for dieselengines is important for satisfactoryoperation. Determine which oil viscositybest suits the temperature range youexpect to encounter for the next serviceinterval from the SAE Viscosity Gradeschart.
Note:An engine block heater isrecommended at temperatures below -9°F(-23°C).
