What kind of oil goes in a 1998 ford explorer?

The type of oil for a 1998 Ford Explorer depends on the engine it has. There were several engine options available that year. To know for sure, you need to check your owner's manual or the sticker located under the hood (often near the radiator).

However, generally speaking, 1998 Ford Explorers used either 5W-30 or 10W-30 motor oil. The owner's manual will specify the exact weight and type (conventional, synthetic blend, or full synthetic) recommended for your specific engine. Always follow the manufacturer's recommendations.
