How to Solve the Problem of Increasing Car Fuel Consumption?
2 Answers
Here are the solutions to the problem of increasing fuel consumption: 1. Regular maintenance: Perform regular maintenance every 6,000 to 10,000 kilometers to reduce the accumulation of carbon deposits in the engine; when refueling, choose gas stations with good fuel quality to prevent the intake manifold walls from becoming rough, which affects the intake efficiency and the quality of the air-fuel mixture, leading to increased carbon deposits. 2. Regular carbon deposit cleaning: Perform periodic carbon deposit cleaning every 40,000 to 50,000 kilometers, such as using drip cleaning, foam cleaning, hydrogen-oxygen carbon removal machines, or manual disassembly and cleaning. 4. Regular replacement of spark plugs: The purpose of regularly replacing spark plugs is to use high-voltage electricity to generate sparks to ignite the air-fuel mixture. If damaged, the ignition energy will decrease, causing uneven combustion of the air-fuel mixture, which slows down acceleration and increases fuel consumption. 5. Frequently check tire pressure and tire wear: Frequently check tire pressure and tire wear. If the tire pressure is too low, the friction between the tires and the ground will increase, leading to greater resistance and higher fuel consumption. The normal tire pressure is around 2.5 bar, and it can be appropriately reduced in summer.
As an experienced veteran driver, I've found that when a car's fuel consumption suddenly increases, the first step is to check basic maintenance issues. Insufficient tire pressure increases rolling resistance—I recommend using a pressure gauge to inflate tires to the manufacturer's recommended value (usually found on the door edge or in the manual), making immediate adjustments when low. A dirty air filter restricts airflow, forcing the engine to burn more fuel to compensate, so I regularly clean or replace mine every six months. Aged engine oil becomes viscous, causing insufficient lubrication that increases friction and fuel consumption—I strictly follow mileage intervals (e.g., every 5,000 km) for oil changes to ensure smooth operation. Carbon buildup on spark plugs leads to incomplete ignition and inefficient combustion, raising fuel consumption; I clean or replace spark plugs every 20,000 km. Also pay attention to fuel system components like clogged fuel injectors—promptly clean them or use fuel additives. These minor adjustments effectively reduce fuel consumption and prevent more serious issues.
