Factory Service Intervals
Ford's Intelligent Oil-Life Monitor (IOLM) system is designed to notify you when an oil change is due, taking into account your driving habits and conditions. While the IOLM is a great tool, a general guideline for conventional oil changes is every 5,000 to 7,500 miles, or every 6 months, whichever comes first. For synthetic oil, this can extend to 7,500 to 10,000 miles or 12 months. Always consult your owner's manual for the most accurate and up-to-date information, and remember that extreme driving conditions may necessitate more frequent service.
