How to Solve High Fuel Consumption in Focus?

If it's a carbon deposit issue, carbon cleaning can be performed. It's better to have an experienced professional at an auto repair shop handle this. If it's a fuel quality problem, it's advisable to use higher-quality engine oil. Although premium fuel is more expensive, it keeps the fuel system cleaner, reduces carbon deposits, and results in relatively lower fuel consumption. Older vehicles must use fuel system cleaners. These cleaners can effectively reduce fuel consumption, clean the fuel lines, and even enhance engine power. Regular maintenance can effectively remove engine carbon deposits and other impurities, thereby reducing the vehicle's fuel consumption.
As a veteran driver who's been driving a Focus for ten years, let me share some tips. A sudden increase in fuel consumption is most commonly caused by driving habits. Try to avoid sudden acceleration and hard braking, especially in city traffic—that stop-and-go driving style burns the most fuel. Here's a little trick: check your tire pressure regularly. Low tire pressure increases the contact area between the tires and the road, making the car work harder to move. If you've checked all these and still have issues, it's time to inspect the spark plugs and air filter. Carbon buildup is quite common in Focus models, and sometimes cleaning the throttle body can save a significant amount of fuel.
I recommend investigating from these three aspects: engine maintenance status, fuel system cleanliness, and vehicle load conditions. First, check if the air filter is clogged - this thing affects air intake efficiency and should be replaced every six months. Also, avoid using low-grade fuel for extended periods as excessive carbon deposits will deteriorate fuel injector atomization. Remove unnecessary items from the car immediately - that case of mineral water in the trunk alone could increase fuel consumption by half a liter. For vehicles over five years old, it's advisable to check the oxygen sensor data as this component directly affects fuel injection precision. By the way, running the AC at maximum settings also increases fuel consumption - remember this basic knowledge: opening windows on highways consumes more fuel than using air conditioning.
