Petrol Grand C-Max servicing (EcoBoost and Duratec)
Petrol Ford Grand C-Max engines in this range include EcoBoost and Duratec units, and they generally rely on regular oil and filter changes to protect turbochargers (where fitted) and timing components. Service intervals can vary substantially across engines and years, so treat any oil-change window as a guide until you select your exact engine. Alongside routine fluid and filter checks, pay attention to spark plug condition and any misfire symptoms, as these can affect performance and fuel economy. If your schedule specifies a timing belt, follow the stated time and distance limits rather than stretching intervals.
