Ford Focus Owners Manual: Technical specifications

Vehicle fluids

1 Providing it meets the specification defined by WSS-M2C913-C, you can also use Ford Engine Oil or an alternative engine oil.

2 On vehicles with a 2.5L Duratec-RS engine, use only this oil.

Topping up the oil: If you are unable to find an oil that meets the specification defined by WSS-M2C913-C, you must use SAE 5W-30 (preferred), SAE 5W-40 (except vehicles with E85 fuel) or SAE 10W-40 that meets the specification defined by either ACEA A5/B5 (preferred) or ACEA A3/B3. Using these oils can result in longer engine cranking periods, reduced engine performance, reduced fuel economy and increased emission levels.

Castrol engine oil recommended.
