We recommend Motorcraft motor oil for your vehicle. If Motorcraft motor oil is not available, use motor oil of the recommended viscosity grade that meets our specification WSS-M2C171-F1. You can find the list of approved motor oils at www.motorcraft.com.
Do not use engine oil additives as they could lead to engine damage not covered by your vehicle warranty.
The use of correct oil viscosities for diesel engines is important for satisfactory operation. Determine which oil viscosity best suits the temperature range you expect to encounter for the next service interval from the SAE Viscosity Grades chart.
