Additional Notes
- The Ford Focus Mk III, C346 (EU) 2.3 RS EcoBoost (257 kW) carries a rear differential fluid capacity of 1 liter, which is consistent with a standard service fill volume for a compact performance vehicle's rear differential unit.
- A separate special additive capacity of 0.06 liter is specified alongside the primary 1-liter fill, indicating the rear differential requires a friction modifier or similar additive introduced as a distinct measured quantity rather than blended into the base fluid volume.
- Both the 1-liter fluid capacity and the 0.06-liter additive capacity apply under normal use conditions, meaning the specification is not tied to a severe-duty or break-in service scenario.
- The presence of a rear differential on the Focus 2.3 RS EcoBoost (257 kW) reflects the all-wheel-drive configuration of the RS variant, which distinguishes the drivetrain layout from front-wheel-drive Focus models that would carry no rear differential fluid specification at all.
