The price of oil has finally dropped today,

It's really expensive to keep a car!

The first thing you need to do when you're driving is to pick a fuel efficient car

The second thing is to choose a road that is not blocked.

How much speed can we drive on an open road to save fuel?

That's what we usually call economic speed.

Some friends say 80 km/h,

Some say 100 km/h, others say the faster the better,

Let's unveil the results together!

The economic speed of most manufacturers is 60-80km/h

In fact, the economic speed of different models is also different, but they are basically 90km/h up and down. Most of the household cars have an economic speed of 60-80km/h. If the speed is too low, the movement speed of the piston is low, which will lead to inadequate fuel combustion. If the speed is too high, the air intake speed will increase the air intake resistance, and at this time the air resistance coefficient will increase, so the fuel consumption will also increase.

Small displacement, low economic speed, high displacement

In fact, the larger the displacement and the lower the center of gravity, the higher the economic speed of a car similar to a sports car. Basically, the economic speed of cars with displacement less than 2.0 is between 45 km/h and 65 km/h, and that of cars with displacement more than 2.0 is between 55 km/h and 80 km/h, or even higher.

How can I know the economic speed of my car?

In fact, it's not very difficult to identify the method. Nowadays, most cars have the parameter of "instantaneous fuel consumption". You can keep the car running at a certain speed at a constant speed, try several more speeds, and then look at the instantaneous fuel consumption of these speeds. The value is low and stable, which is almost the economic speed.

But although economic speed can save fuel, we can't just keep driving at that speed. For example, driving at high speed, you can't drive a tortoise speed car to save fuel. This is very dangerous. After all, compared with saving fuel, life is the most important thing.

Besides, what else can we do to save fuel?

1. Minimize the use of brakes

In fact, the way of "one start and one stop" is very expensive. It's better to let it slow down slowly; when passing the intersection or downhill section, you can loosen the accelerator in advance to let the car slow down naturally, which will save more fuel.

2. Reduce car load

If the load is reduced, the fuel consumption will be reduced a little. So don't put things like those that don't have much use in the car.

3. Ensure normal tire pressure

If the tire is abnormal, it will also increase the fuel consumption. Therefore, when the four-wheel positioning is to be done, it must not be dragged and done in time. This not only saves fuel, but also ensures driving safety.

How to drive to save fuel?

Poor driving, such as frequent speeding, rapid acceleration, sudden braking, random lane changes, etc., will affect fuel consumption, which is 10% to 40% more expensive than driving at a steady and constant speed. That is to say, we should form the habit of not rushing or impetuous driving and avoid bad driving behaviors, so that we can save a lot of fuel bills in one year.
