Service Intervals:

Ford recommends servicing the Focus RS Mk3 every 12 months or 10,000 miles (16,000 kilometres), whichever comes first. Adhering to these intervals is crucial for maintaining the car’s performance, reliability, and warranty (if applicable).

Scheduled Maintenance:

Here's a breakdown of the typical service requirements at each interval. Keep in mind that this can vary depending on driving conditions and individual vehicle needs.

Every 12 Months or 10,000 Miles (16,000 km):

  • Engine Oil and Filter Change: This is the most frequent service item. Use the correct specification oil recommended by Ford for the 2.3 EcoBoost engine. A new oil filter should always be fitted at the same time. Check out our service pack consisting of Genuine Ford items here
  • Tyre Condition and Pressure Check: Inspect tyres for wear, damage, and correct pressure. Ensure proper wheel alignment.
  • Brake System Check: Inspect brake pads, discs, and lines for wear and leaks. Check brake fluid level. Check out our wide range of braking options for your RS here
  • Fluid Level Check: Check and top up (if necessary) all fluid levels, including coolant, power steering fluid, brake fluid, and washer fluid.
  • Visual Inspection: A general inspection of the vehicle, including lights, wipers, horn, and other components.
  • Cabin Filter Change: Replace the cabin filter to ensure clean air inside the car. We recommend sticking with the Genuine Ford cabin filter here

Every 24 Months or 20,000 Miles (32,000 km): (In addition to the 12-month service items)

  • Air Filter Replacement: Replace the engine air filter to maintain proper airflow to the engine. Consider swapping to an aftermarket performance filter, check out our range here
  • Spark Plug Replacement: The 2.3 EcoBoost is a high-performance engine, and spark plugs should be replaced at the specified interval.
  • Brake Fluid Change: Brake fluid absorbs moisture over time, so it needs to be flushed and replaced. Consider swapping to a higher performance fluid if you use the vehicle hard, Motul's RBF600 is perfect for this application.
  • Coolant Check: Check the coolant strength and top up or replace as needed.

Every 36 Months or 30,000 Miles (48,000 km): (In addition to the other service items)

  • Transmission Oil Change: The manual gearbox oil should be changed.
  • Rear Differential Oil Change: The rear differential oil requires changing to ensure smooth operation of the AWD system.

Other Important Maintenance Considerations:

  • Regular Inspections: Between scheduled services, it's a good idea to perform regular checks of fluid levels, tyre pressures, and general vehicle condition.
  • Performance Driving: If you frequently drive your RS hard, you may need to perform certain maintenance tasks more frequently, such as oil changes and brake inspections.
  • Head Gasket Issues: Be aware of the potential for head gasket issues with the 2.3 EcoBoost. Monitor coolant levels and watch for any symptoms. Early detection is crucial.
  • Software Updates: Ensure your car has the latest software updates from Ford. These can address various issues and improve performance.
  • Wheel Alignment: Maintaining correct wheel alignment is important for tyre wear and handling.
  • Tyre Choice: Using the correct tyres for the RS is essential for optimal performance and safety.
