Engine Oil Recommendations - Ford Ranger Owner's Manual

Engine Oil Recommendations

We recommend using Motorcraft oil or an equivalent oil
meeting Ford Specification WSS-M2C153-F and displaying the
American Petroleum Institute CERTIFICATION MARK on the
front of the container.
The API Certification Mark
Never use:
"Non-Detergent" oils
Oils labeled API SA, SB, SC, SD, SE, SF or SG
Additional engine oil additives, oil treatments or engine
treatments
Engine oils with an SAE 5W-30 viscosity are PREFERRED for
your vehicle. They provide the best engine performance, fuel
economy and engine protection for all climates down to -15˚F
(-25˚C).
Synthetic engine oils which are CERTIFIED and of the preferred
viscosity may be used in your engine. The engine oil and oil
filter must still be changed according to the maintenance
schedule.
