What are the reasons for the high fuel consumption of the Weiwang M20?

[SawyerDella]

The specific reasons for the high fuel consumption of the Weiwang M20 are as follows: 1. The vehicle has not been maintained for a long time: Dirty engine oil and air filters can lead to increased fuel consumption. Dirty engine oil results in poor lubrication, increasing resistance in the engine's moving parts and requiring more energy to overcome this resistance, which in turn increases fuel consumption. 2. Spark plugs: Spark plugs are often overlooked. Some vehicles have traveled over a hundred thousand kilometers without replacing the spark plugs. Although the spark plugs may still function, insufficient ignition energy can cause delayed ignition, missing the optimal ignition timing. This leads to partial power loss, as energy is not effectively used for work, and also results in incomplete combustion, further increasing fuel consumption.
