Driving a car every day, regular car care and maintenance is very important. However, there are some bad habits when driving a car that cause serious irreparable damage. In this article, CarOn will list bad habits when driving a car, thereby helping drivers gain more driving experience.

Depart without warming up the engine

Start the car without warming up the engine

Warming up the engine is a good thing to do before going on a journey with your car, especially when it has not been used for a long time. Hasty starting is a common one among drivers. Limit this, let the car run in place for a minute or two before moving, this will help the engine oil circulate evenly to the parts. On the contrary, if you move immediately, it will create great pressure on the engine components, causing special harm to diesel trucks.

Try to drive when the gas tank is low

Try to drive when the gas tank is low

The habit of driving when the fuel tank is almost empty is not good because the fuel at the bottom of the fuel tank is often filled with impurities such as sediment and debris. If this situation continues for many days, these impurities will clog the fuel filter and pipes, leading to more repair costs.

Therefore, to keep the fuel pump in good condition, you must keep at least one-quarter of the fuel left in the tank.

Drive fast continuously

Driving fast continuously for a long time will cause fuel consumption to increase greatly. However that is not all.

This dangerous habit when driving a car causes parts of the powertrain, suspension setup and braking system to be affected by having to operate very strained compared to normal.

Drive fast continuously

Increase engine rpm too high

The engine is designed to operate at a certain rpm and will be electronically limited to a certain level. The automatic transmission also prevents the driver from increasing the engine rpm too high by automatically shifting to a high gear when the engine rpm increases and keeping the rpm at the most optimal level.

However, on manual transmissions, the driver is not bound by that, leading to sometimes the engine rpm being too high, and this is also dangerous and gradually damages the engine if the driver does not change gears at the right time.


The car is too heavy

While many people often think that this does not affect the car too much, they do not know that this habit causes the weight of the car to increase, negatively affecting fuel consumption, reducing system performance. shocks and brakes.

Modern cars are designed to carry heavy loads, but that doesn’t mean they can be overloaded. The owner’s manual will usually tell the user the maximum load weight of the vehicle. The greater the weight, the more pressure is placed on the brakes, suspension and transmission.

It’s also important to note that while leaving unnecessary items – like golf clubs or exercise equipment in the trunk – won’t add stress to the car’s components, it will affect affects the car’s fuel economy and can affect car emissions.

Change gear before stopping the vehicle

Shifting between reverse and drive (and vice versa) in a car equipped with an automatic transmission is not good for the transmission. The automatic transmission is designed to change gears – while the brakes do the job of stopping the vehicle.

Shifting gears before stopping causes wear and tear on the transmission line, rather than the brake discs and brake pads, which are designed to corrode.

The same thing happens on manual transmission cars, so the driver should come to a complete stop before shifting into reverse (although most modern cars will not allow shifting without stopping).

Brake suddenly, often press the pedal

Frequently press the pedal

When you step on the gas pedal to speed the car away, it will bring a feeling of excitement to the driver’s brain. However, it actually consumes a lot of fuel. Suddenly applying the brakes can cause the vehicle to go downhill quickly, the steel brake discs can become bent and the brake pad material can wear out. Therefore, to prolong the life of brakes and vehicles, drivers should only use them when encountering dangerous situations.

Do not slow down when going over potholes

The act of driving at high speed into potholes or driving over speed bumps without slowing down can cause the wheel to warp, tire blowout or serious damage.

Suddenly shifting gears to forward while the vehicle is in reverse

Unexpected gear changes are one of the major causes of damage to the vehicle. It is known that when backing out of a parking lot, drivers often immediately shift forward and step on the accelerator to drive the car forward before being able to stop completely. According to car driving experience, the transmission system is still in the process of reversing and suddenly being forced to change in the opposite direction will cause the gearbox and driving shaft to rapidly degrade; causing drivers to have to go for maintenance more often.

Although the steering wheel cannot completely prevent vehicle deterioration or problems during use. However, controlling vehicle usage habits will greatly contribute to extending the car’s operating life. This will help the car last longer and the driver can limit the number of times the car is maintained during the year.

Not changing brake fluid regularly

Not changing brake fluid regularly

Brake fluid (brake fluid) is a very important fluid in the car brake system. Brake fluid has the following effects:

  • Ensuring the transmission of force from the brake pedal to the brake system components in the most accurate and flexible way, even in high and humid temperatures;
  • Ensure good lubrication for the vehicle brake system;
  • Resists corrosion, oxidation, protects the vehicle brake system;
  • Improve the life of your vehicle and braking system.

Some drivers do not have the habit of regularly changing brake fluid. Brake fluid that has not been changed for a long time, contaminated by moisture or mixed with water, will hinder braking ability and lead to the following consequences:

  • Degraded brake system: Brakes are less lubricated, have poor power transmission, leading to poor braking, potentially dangerous when operating the vehicle;
  • The parts in the brake system are damaged: When the brake fluid becomes wet, it will rust the brake parts.

Therefore, car owners should change brake fluid every 2-3 years or 30,000 km. In addition, when you detect the following signs: poor brake performance, brake fluid that has a strange color or has dropped to the minimum level in the oil tank, or parts of the brake system that are corroded, you should also have the vehicle checked. Check and replace brake fluid if necessary.

Not servicing your brakes regularly

Don’t mistakenly think that changing lubricating oil is routine brake maintenance. Car brakes need to be maintained on schedule to remove plaque on the contact surface, detect errors in the brake system, and avoid the risk of brake pads getting stuck and the brakes not working as expected by the driver.

Above are 5 bad habits that wreak havoc on your car’s braking system. Drivers should give up these habits as soon as possible before unfortunate consequences occur.
