The fuel consumption of 16 fit is above 10 liter. How to find out the reason? The air intake and throttle valve have been cleaned.

Tire pressure: If the tire pressure is too high, the wheel diameter will become larger, and the actual mileage will be more than the mileage displayed by the odometer, resulting in high calculated fuel consumption; Low tire pressure increases the resistance between tire and road surface, and also increases fuel consumption. Taking radial tires as an example, when the air pressure is 0.5 air pressure lower than the standard value, the fuel consumption will increase by 4%. Tire pattern: Different types of tires have different fuel consumption rates, so choosing zigzag tires is helpful to save fuel, and choosing radial tires saves fuel by 6% ~ 8% compared with ordinary bias tires. Tire wear: If the tire is seriously worn, it will often slip and increase fuel consumption. Consider changing a new tire at this time. Fault of bearing and braking system: If abnormal noise is found in the wheels during driving or starting, check whether there is fault of bearing and braking system in time. If the wheel rotates abnormally, it will affect the speed and increase fuel consumption. Clutch slippage: Clutch slippage will cause the engine speed to decrease. When you find that the engine tachometer increases rapidly when accelerating rapidly, but the speed increases slowly, you can judge that the clutch is slipping. At this time, the clutch plate, clutch pressure plate and driving wheel need to be replaced.
