The recommended motor oil for a 2001 Ford Ranger depends on the engine it has. Ford Rangers of that year came with several different engines. To know for sure, you need to check your owner's manual. It will specify the correct oil weight (e.g., 5W-30, 10W-30) and the type (conventional, synthetic blend, or full synthetic).
However, 5W-30 is a common and generally safe recommendation for many 2001 Ford Ranger engines. But again, always consult your owner's manual for the definitive answer. Using the incorrect oil weight or type can damage your engine.
