The Ford Excursion diesel, particularly those equipped with the 7.3L Power Stroke engine, typically uses 15W-40 or 5W-40 diesel engine oil, depending on the climate and specific requirements. It's essential to choose oil that meets API (American Petroleum Institute) specifications, such as CI-4 or CJ-4, for optimal performance and engine protection. Always refer to the owner's manual for the recommended oil type and specifications.
