How to Reduce Increased Fuel Consumption?

[Herbert]

To address increased fuel consumption, you can clean engine carbon deposits and inspect the oxygen sensor. Here are more relevant details: 1. Regularly replace the three filters: During vehicle use, the oil filter, air filter, and fuel filter must be replaced periodically. If not replaced for a long time, they can become dirty and clogged, affecting performance and sending incorrect information to the engine control unit, leading to incomplete fuel combustion and increased engine carbon deposits. 2. Inspect the electronic control unit: Although the engine's electronic control unit is highly reliable, older vehicles may experience various issues, such as damaged integrated circuits, loose bolts, soldering joint failures, or malfunctioning resistors and capacitors. Problems with the engine control unit can directly cause difficulties in starting, increased fuel consumption, poor power performance, and thick black exhaust emissions.

Recently, my car's fuel consumption has skyrocketed, which I find quite annoying, so I've summarized some tips. Checking tire pressure weekly is a must, as insufficient pressure increases rolling resistance, forcing the engine to burn more fuel. I also avoid sudden acceleration and hard braking, especially when driving in the city, learning to coast to a stop for better fuel efficiency. On highways, using cruise control helps maintain a steady speed and avoids frequent speed changes. I don't neglect engine maintenance, changing the oil and air filter every six months to ensure combustion efficiency. Additionally, removing unused items from the trunk to reduce weight also helps. I often plan routes using navigation to avoid congested areas. These habits have helped me save a lot on fuel costs each month and also extend the car's lifespan.

I enjoy delving into car data, so all my fuel-saving tricks come from experimentation. First, I used an OBD-II scanner to read real-time fuel consumption and noticed it spikes during rapid acceleration, so I switched to smoother starts. I regularly check tire pressure and wheel alignment because misalignment can cause the car to drift and increase fuel usage. I insist on using high-quality gasoline with fewer impurities to keep the engine clean and efficient. Vehicle weight reduction is also crucial—I removed the roof rack to reduce wind resistance. I inspect the engine quarterly and clean the fuel injectors to improve combustion efficiency. I also installed a tire pressure monitoring app for real-time alerts. These techniques have steadily lowered my fuel consumption, saving me a lot on long trips.

After decades of driving, I've learned simple ways to reduce fuel consumption. I avoid sudden acceleration and start gently to prevent revving too hard. After a cold start, I minimize short trips since cold engines are less efficient. I never skip maintenance, changing the air filter quarterly to ensure smooth airflow. I check tire pressure frequently, keeping it at the manufacturer's recommended level. I avoid overloading the trunk, as extra weight increases fuel use. In the city, I drive during off-peak hours (morning or evening) to avoid traffic jams, keeping the engine running smoothly. These habits help me maintain low fuel consumption, saving money and giving peace of mind.
