What to Do When Your Car's Fuel Consumption Increases?

[VonCarmen]

If your car's fuel consumption is high, you can take the following measures: 1. Pay attention to fuel quality and clean carbon deposits: Poor-quality gasoline can lead to increased carbon deposits in the engine. Excessive carbon deposits can roughen the intake pipe walls, affecting the intake efficiency and the quality of the air-fuel mixture. For example, the kinetic energy that could be produced by 1 liter of fuel may now require 1.5 liters to achieve, causing a significant rise in fuel consumption. 2. Replace spark plugs regularly: Don't underestimate a small spark plug—its role is to ignite the air-fuel mixture with an electric spark generated by high voltage. If damaged, it can reduce ignition energy, causing uneven combustion of the mixture, slowing down acceleration, and increasing fuel consumption. The lifespan of standard spark plugs is only 30,000–50,000 kilometers, while iridium spark plugs last about 50,000–80,000 kilometers, and platinum spark plugs can last up to 100,000 kilometers. Most domestic car models include spark plug replacement as part of major maintenance services.
