Approximately 4.5 liters of engine oil with the filter installed, and about 3.8–4.0 liters if you do not replace the filter. The Focus ST 225’s capacity can vary slightly by model year and market, so consult the owner's manual or a Ford service bulletin for your exact vehicle.
The Ford Focus ST 225 is the high-performance variant of the Ford Focus from the early 2000s, powered by a 2.0-liter turbo engine. While these figures cover the typical ST 225, exact capacity can differ depending on production year and region. Use the following as a reliable guide and verify with official documentation when possible.
Capacity specifics
Below are the commonly cited capacities for the ST 225 during a full oil change. The numbers reflect whether you replace the oil filter or not.
- Oil capacity with filter: 4.5 liters (approximately 4.7 US quarts)
- Oil capacity without filter: 3.8–4.0 liters
When performing an oil change, technicians typically fill to the 4.5-liter target with a new filter, then top up to the correct level after the engine has run and is cooled and the dipstick is checked.
Oil grade and maintenance
Recommended oil grade
Ford generally recommends a fully synthetic 5W-30 oil for the Focus ST 225 in most climates. In hotter climates or under specific operating conditions, a 5W-40 grade may be advised. Always follow the exact specification in your owner's manual.
Change interval and checks
With synthetic oil, maintenance intervals commonly range around 5,000–7,500 miles (8,000–12,000 kilometers) under normal driving, though severe conditions (short trips, extreme temperatures, or heavy use) may require more frequent changes. Always refer to the vehicle’s service schedule for your exact model year.
