What happened to the rapid decline of the modern Sonata 8 fuel consumption meter at 1 1?

Affected by the temperature, the vehicle has not been maintained for a long time, and the vehicle has accumulated too much carbon.

1, low temperature in winter will increase fuel consumption.

2. Dirty oil and air filter elements will also lead to increased fuel consumption. Dirty oil leads to poor lubrication and increases the resistance of all moving parts of the engine. More energy is needed to overcome resistance and fuel consumption will increase.

3. The places where carbon is deposited are throttle, fuel injector, air inlet and piston crown. Excessive carbon deposition anywhere will lead to incomplete combustion, which in turn will lead to increased fuel consumption.

Basso refers to the eighth generation Sonata, which is also a mid-level car under the contemporary group.
