Engine speed is an important parameter affecting automobile fuel consumption. Generally, it is economical to control the speed of EFI vehicle at about 2200-2500 rpm, and the engine will be damaged if the engine speed is too low and the power is insufficient.

2. Keep the speed:

Speed is also an important factor to determine the fuel consumption of a car. Generally, the fuel consumption of small-displacement family cars is relatively low when the speed is controlled at 60-80 km, and the fuel consumption of medium-displacement cars is relatively low when the speed is 80- 100 km.

Step 3 start gently:

When the vehicle starts, the fuel consumption is relatively high. If you step on the accelerator with your big foot when you start, the fuel consumption will also increase. Gear adjustment and throttle control are determined by the sound of the engine. A reasonable hot car is needed before starting, and the engine can be fully lubricated when driving.
