Petrol C-Max servicing (EcoBoost and Duratec)
Petrol Ford C-Max models span turbocharged EcoBoost and normally aspirated Duratec units, so service requirements can differ between engines and year ranges. Oil and filter changes are central to longevity, with intervals across the range commonly landing between about 10,000 and 30,000 km or 12 to 24 months depending on the schedule for your engine. For EcoBoost engines, keeping to the correct oil specification and interval is particularly important because higher thermal loads can accelerate oil degradation. Many petrol C-Max variants also use long-life spark plugs, so plug replacement is usually a scheduled item rather than a frequent one.
