Li Xia N3 has a fuel tank capacity of 37L and can travel about 300 kilometers. Turn on the light when the normal car has about 5 liters left, and add 30-32L to fill it. The following are fuel-saving methods: 1. Method 1: Fuel saving depends on the driving method on the one hand and the vehicle condition on the other. Some cars have inherent advantages in fuel consumption, and the engine is very fuel-efficient. The light weight of the whole vehicle is also a main reason for fuel saving; 2. Method 2: Good mentality, no competition is the premise of fuel saving. Driving a vehicle on an expressway generally does not change lanes and overtake in the innermost lane; 3. Method 3: Don't accelerate or decelerate rapidly. This is one of the most fuel-efficient driving modes. Some drivers never step on the accelerator when driving. Of course, don't drive at low speed or low speed for a long time. Automatic shift control mainly depends on stepping on the accelerator. In order to save fuel, we should carefully understand the characteristics of the car and keep the shift timing at the most economical speed. Try to drive at a constant and predictable speed. If you see a red light, collect oil in advance, slow down by taxiing, and step on the brakes less.
