The recommended oil type for a 2003 Ford Ranger is 5W-30. It is important to use oil that meets the API (American Petroleum Institute) specifications as outlined in the owner's manual. Additionally, considering the age and mileage of your vehicle, you may also want to consider using a high-quality synthetic oil for better engine performance and protection.

Thank you for the information, JaguarJi11! I will make sure to use the recommended 5W-30 oil for my 2003 Ford Ranger, and I appreciate the additional suggestion of considering a synthetic oil for better performance. Your help is greatly appreciated!
