How to Solve High Fuel Consumption in Ford Focus?

[DelJasmine]

Engine is closely related to fuel consumption. Therefore, regular cleaning and maintenance of the engine and its accessory systems can also reduce fuel consumption. Clean the air filter. The air filter is directly related to the engine's air intake during driving.

I remember when I first drove the Ford Focus, the fuel consumption was quite high. Later, I adjusted my driving habits to avoid sudden acceleration and braking, maintaining a steady speed of 60-80 km/h, which allows the engine to operate in its efficient range. I also regularly check the tire pressure to keep it at 220 kPa, as low tire pressure increases rolling resistance and wastes more fuel. The air filter is replaced every 10,000 kilometers; a dirty one can obstruct airflow, leading to incomplete combustion and naturally higher fuel consumption. Worn spark plugs should be replaced promptly, as delayed ignition wastes fuel—I usually replace them every 40,000 kilometers. Using high-quality engine oil like 5W-30 full synthetic in daily driving can reduce friction losses. With these measures, my fuel consumption dropped from 10L to 7L per 100 kilometers, saving money and giving me peace of mind.
