Ford Fiesta Oil Change Interval

Recommended Intervals

• Every 10,000 miles (16,000 km)
• Or every 12 months, whichever comes first

Heavy-duty driving reduces the interval:

• Frequent short trips
• Stop-start city usage
• Towing
• Extreme temperatures
• High-speed motorway driving

Under these conditions, change oil every 6,000 miles.

How to Perform a Ford Fiesta Oil Change (Step-by-Step)

Tools Needed

• New Ford-approved oil
• New oil filter
• 8–13mm socket set
• Oil drain pan
• Funnel
• Gloves
• Torque wrench (for correct sump plug tightening)

Oil Change Procedure

1. Warm the engine lightly to thin the oil.
2. Raise the car safely using axle stands.
3. Remove the undertray (if applicable).
4. Place the drain pan beneath the sump plug.
5. Remove sump plug and allow oil to drain fully.
6. Remove old oil filter and install the new one with a light oil film on the gasket.
7. Refit sump plug to recommended torque.
8. Refill engine with the correct oil grade (see tables).
9. Start engine, check for leaks, verify oil level.
10. Reset the Fiesta service/oil reminder.
