Mercedes-Benz C-Class Mileage

Diesel Particulate Filter (DPF) Regeneration: The DPF system needs to be regularly regenerated to remove all the accumulated soot. If you often use your vehicle for frequent short trips, this process can be hindered, and fuel efficiency will be reduced.

Fuel Quality: Poor-quality diesel fuel can hurt engine performance and fuel economy. Use premium diesel fuel for best performance.

AdBlue Fluid: Emissions reduction using the AdBlue fluid can impact fuel consumption. Make sure the AdBlue tank is full to avoid any disruptions.

Driving Style: Both diesel and petrol variants of the C Class can endure a significant impact on fuel efficiency from aggressive driving, such as frequent acceleration and braking.

Spark Plug Condition: Old spark plugs can reduce combustion efficiency, consuming more fuel. Replace them according to the manufacturer's recommendations.

Fuel System Maintenance: Cleaning the fuel system can prevent deposits and keep an engine running at the best performance levels.

Air Filter Condition: A dirty air filter can impede the air that enters the engine, thus affecting fuel efficiency. Replace it as needed.

Weight: Excess weight to carry can cause excess fuel consumption. Get rid of any items from the trunk or passenger compartment that you don’t need.

Tire Pressure: Tires inflated below their factory-recommended pressure can increase rolling resistance and decrease fuel efficiency. So, check their tyre inflation.

Traffic Conditions: Under heavy traffic or stop-and-go conditions frequent acceleration and deceleration can lead to increased fuel consumption.

Weather Conditions: Fuel efficiency can be affected by extreme weather — like cold temperatures or strong winds.

Overall Maintenance: Engine performance, fuel efficiency, and overall vehicle performance depend on regular maintenance that includes oil changes, filter replacements, and brake inspections.
