Unnecessary work for cars.

However, not every investment is worth the money. Therefore, careful consideration is necessary before making a purchase. Below are some unnecessary things to do with your car, as recommended by many experts.

Premium fuel

Each type of vehicle is designed to use a specific type of gasoline depending on the engine's compression ratio. Many people think that using higher-quality gasoline will help maintain durability and increase performance, but they may be mistaken; in fact, this could end up costing drivers much more money.

In fact, prolonged use can reduce a car's performance or cause other damage, leading to serious consequences. Therefore, it's unnecessary to use premium gasoline for your car.

Inflating car tires with nitrogen gas.

Many garages now use nitrogen gas as a substitute for compressed air to inflate car tires. In theory, pure nitrogen is less compressible and more elastic than compressed air.

In fact, 78% of compressed air is already nitrogen, so there isn't much difference here.

If replacing these two types of gas is inexpensive, drivers can use them. However, if they have to pay extra, drivers should stick with the old system to save costs.

Fuel economy kit conversion

Automakers have spent billions of dollars researching fuel-efficient technology, so drivers should trust the manufacturers more than the "tricks" of garages.

Garages can replace kits, air filters, or even throttle bodies to help the engine consume less fuel. However, in the long run, this will only shorten the engine's lifespan, cause damage, and be more expensive to fix.

Instant car care tools

The automotive accessories market is very diverse, with many products that drivers can't ignore, including immediate car care tools: tire sealants, anti-rust paint, vacuum cleaners, etc.

At first glance, most of these products seem necessary for car users in emergencies, but in the long run, they can cause undesirable side effects.

Using them is only beneficial in the short term; later on, the damage they cause can lead to headaches for drivers and significantly higher maintenance and repair costs.

Equipped with a turntable, sound system, and TV.

This is a very common habit among car owners. They often invest heavily in entertainment systems such as: upgrading the original sound system, changing to multi-colored LED lights, replacing the screen, adding a TV to the car, and even equipping the car with expensive, brightly colored rims for aesthetic purposes.

However, from a practical standpoint, these actions do not benefit the vehicle and only add to the driver's expenses.

Changing engine oil too soon

Changing engine oil is essential for maintaining smooth engine operation. However, simply changing the oil isn't always good for the engine. Car owners need to change the oil at the right time, neither too early nor too late. The manufacturer's recommended oil change interval is 8,000-11,000 km for optimal performance.

Vehicles that operate under harsh conditions should have their oil changed sooner, around 4,000-5,000 km.

Each car manufacturer has different regulations regarding the timing of engine maintenance for new cars. However, the first maintenance typically occurs between 3,000km and 5,000km, equivalent to 3-6 months of vehicle use from the time the car is first put into operation.

For initial maintenance, car owners should take their vehicles to a repair center instead of doing it themselves. This is a crucial step for the long-term operation of the vehicle, so car owners should not take it lightly.

Whether it's a newly purchased car or a used one, regular oil changes are essential to ensure the vehicle's longevity. When changing engine oil, car owners should carefully consult with a maintenance expert about the appropriate type of oil for their specific vehicle model to ensure optimal performance.
