What are the reasons for the high fuel consumption of the classic Focus?
2 Answers
The reason for the high fuel consumption of the classic Focus is that it is equipped with a 1.8L naturally aspirated engine. The higher the power, the higher the engine speed naturally, and the higher the maximum speed of the car, which also increases fuel consumption. The following is a detailed introduction about the car's fuel consumption per 100 kilometers: 1. Overview: The fuel consumption per 100 kilometers refers to the fuel consumption of a vehicle traveling 100 kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. The fuel consumption per 100 kilometers is the value measured by the manufacturer in an objective environment using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated at a specified speed to obtain the theoretical experimental fuel consumption data per 100 kilometers for the model. 2. Others: Since most vehicles approach their economical speed at 90 km/h, the theoretical fuel consumption published by most manufacturers is usually the fuel consumption per 100 kilometers at 90 km/h.
Having driven a classic Focus for over a decade, I've found that high fuel consumption is most commonly caused by engine aging and driving habits. Worn-out spark plugs lead to untimely ignition, resulting in incomplete fuel combustion and wasted emissions. A clogged air filter restricts airflow, significantly reducing engine efficiency. Low tire pressure increases rolling resistance, making every kilometer more fuel-intensive. A faulty oxygen sensor causes the ECU to mismanage fuel injection, leading to excessive consumption. Aggressive acceleration and braking habits are even worse, with sudden RPM spikes being the most costly. It's advisable to regularly inspect these critical components; replacing spark plugs and filters can make a notable difference. Maintaining steady speeds while driving, minimizing abrupt speed changes, and reducing AC usage in summer also help. Consistently applying these practices can reduce fuel consumption by up to 20%.
