However, generally speaking, you should look for:
* Oil Type: 5W-20 or 5W-30 synthetic blend or full synthetic oil. Again, check your owner's manual for the *specific* recommendation for your year and model. Using the incorrect weight can damage your engine.
* Oil Certification: Look for an oil that meets Ford's specifications (often denoted on the bottle). This will usually include certifications like API SN or SP (or later).
Crucially: Consult your owner's manual. This manual, specific to your year and model Ford Ranger, will list the exact type and weight of oil recommended by Ford. This is the only way to be absolutely certain you're using the correct oil for your engine.
