is it bad to always drive in eco mode?

Today, almost all modern cars are equipped with a system with which the driver can select the driving mode. As a rule, such equipment is found even in basic configurations. Consider what modes are in this system and what mistake many drivers make.

Every car owner has their own driving style. Someone prefers to move at a speed of 50-60 km / h in order to save fuel, and for some, even 140 km / h seems like a trifle. Not everyone knows that a lot depends on the driving style in the operation of the car.

Many people ask if is it bad to always drive in eco mode and how dangerous is it. So here in this article, we will discuss this in detail.

What is Eco Mode and Why it is important?

The problem of high fuel costs in the automotive industry has always been. To create a powerful car, you need to be sure that people will buy it. After all, such a machine is a transport that has an increased “appetite”. As a result, for the past few years, all dreams of running super-fast cars have been just dreams. Of course, some manufacturers decided to produce such models, but they did not reach mass production.

The problem was partially solved when the ECO mode of engine operation was invented. Manufacturers began to massively introduce such a function since in practice it reduced fuel consumption and emissions of harmful substances into the atmosphere. ECO mode is the most economical mode today. Despite these advantages, even this feature is not without its negative sides.

ECO mode is now available in almost all modern cars. But the budget and basic versions were not lucky – as a rule, they do not provide such an option. Maybe not everything is so bad? Those drivers who are led by stories about the wonders of the ECO mode think they are saving money on fuel. And it really is. But if you use this option constantly, you may be faced with the need for costly repairs to the engine. 

how ECO mode work?

First, let’s look at how ECO mode work.

When the driver turns on this function, the onboard computer is connected to work and starts to save fuel as much as possible. To do this, the revolutions are kept very close to idle. At the same time, the automatic transmission engages an increased gear.

dynamics of car drop significantly

Under such circumstances, the dynamics of the car drop significantly. It takes a lot of effort and time to perform maneuvers. But fuel is really saved – a couple of grams per trip. As for the engine itself, it is subject to the highest load. Recall that even in a driving school, an instructor teaches everyone that you can’t drive at low speeds all the time, because this can kill the engine. So it turns out that the ECO mode harms the engine. Under normal conditions, the volume of oil that passes through the engine system is proportional to the speed. Accordingly, at low rates, the cylinders receive a very small amount of technical fluid.

If the driver in ECO mode forces the car to run at full speed, we can safely say about the rapid wear of almost all elements of the cylinder-piston group. This is explained by the fact that engine oil performs several functions at once – it lubricates rubbing surfaces and cools the pistons. We conclude that saving on fuel at one moment can lead to engine failure.

ECO Mode is big test For cars with automatic transmissions

After all, under such conditions, the transmission tries to drive in high gear. Now let’s imagine what will happen to the gearbox if you drive in ECO mode in a traffic jam. At the beginning of the movement, the box abruptly shifts from first to second gear, and then back. Too frequent shifts increase the wear of the gearbox components. Especially dangerous in such circumstances is the ECO mode for robotic boxes.

low road safety

Another significant drawback of this option is low road safety. This applies only to those who do not understand when and how to use the function. Suppose the driver has turned on economy mode and sees a slug on the road. The thought immediately arises in my head – to overtake and go further. But in ECO mode, this cannot be done so quickly. As a result, an accident may occur.

How dangerous is ECO mode?

How dangerous is ECO mode

Despite these benefits, the option can greatly harm the engine and this usually happens gradually if the driver uses it constantly. Its action is well reflected in fuel economy. Some instances in this mode can drive up to 700 km on a full tank. However, this option should not be used every time, as its frequent use harms the car. With its action, the transmission also starts to work in a different mode and shifts gears only in available cases. The arrow on the tachometer starts to bounce already at 2000 rpm. This leads to the fact that the performance of the pump in the fuel system decreases, and this, as everyone knows, provokes oil starvation. The gaps between the pistons and cylinders begin to expand, and because of this, the driver begins to feel increased vibration.

In the cold period, this mode should not be abused, as this leads to a longer warm-up of the engine.

No matter how paradoxical it may sound, it is also not necessary to refuse to use the ECO mode. Sometimes the machine needs to be allowed to rest and run at reduced power.

Conclusion

The ECO mode in the car can help out in some situations when you need to get to a place, and the level of gasoline in the tank is critically low. However, this function is not suitable for daily use. If you use it on every trip, you can get breakdowns that require expensive repairs.
