Oil type and change interval

Choosing the right oil and following a regular change schedule helps maintain engine health and performance.

Recommended oil grade and type

Oil change interval

• Typical interval ranges from 5,000 to 7,500 miles depending on oil type and driving conditions.


• Ford’s maintenance schedule or an on-board oil life monitor provides the recommended interval for your vehicle.

To stay within recommended guidelines, monitor your oil life indicator (if equipped) and follow the service schedule in your owner’s manual. Regular oil changes help preserve engine longevity.

Practical tips for checking and refilling

For a quick, reliable check and refill, follow these best practices.

• Always use the correct filter size and a fresh gasket on the drain plug when changing the oil.


• Dispose of used oil properly at a recycling facility or service shop.


• After refilling, check the oil level using the dipstick and run the engine to operating temperature before rechecking.

Ensuring the correct quantity and level helps prevent overfill or underfill, which can impact engine performance and longevity.
