8 misconceptions about car maintenance and use

This is a fairly common concept that old drivers advise young people. However, in reality, when the tire is inflated too much, it will lose the shock absorption effect of the wheel, reducing the braking efficiency significantly. If the tire is under-inflated, it will cause instability in vehicle control, and braking efficiency will not increase. In addition, inflating the tire not according to the manufacturer's standard parameters can reduce the tire's lifespan, cause explosions and be dangerous when using the vehicle on the road.

Not sure, nowadays sports cars often have large rims (17, 18 inches) and thin tires - but that does not mean the car has the best road grip. The road grip factor is the friction force created by the tire with the road surface, which mainly depends on the vehicle's mass, the quality of the tire rubber, and the chassis structure. Therefore, the type of tire used and the contact area are carefully calculated depending on the manufacturer... Arbitrarily changing to large and thin wheels will lead to consequences such as shaking, vehicle noise, rapid tire wear, and reduced life of load-bearing parts.

ABS brakes have the task of making our sudden braking much smoother and safer. That is true but only when you understand its function. That is, you must understand that ABS, EBD will support a lot but not everything! Driving carefully, anticipating every situation is your guardian angel. Careless driving, speeding, sudden braking, high-speed cornering, lack of experience... will be very dangerous whether the car has ABS, EBD or not.

This is an incorrect concept; this thinking is very dangerous because in a car there are many devices that need lubricating oil to transmit pressure, cool... Each device has suitable lubricating oils such as brake oil, engine oil, gearbox oil... The composition of the oils also has its own parameters and grades, using them mixed together is very dangerous or at least will damage or reduce the life of the car. Besides, new cars will use thinner oil than cars that have traveled many kilometers. Therefore, you should carefully study this issue to avoid losing money and getting sick.

Normally, when driving a manual transmission vehicle at low gear (high rpm), it causes a roaring feeling, making many people worry about the engine; if running at high gear at low speed, the engine does not roar. Therefore, out of habit, many people "increase" the running of high gear at any speed (also known as lazy shifting) - This is a misconception, causing serious reduction in engine life. Because putting a large load on the engine while the rpm is low (the oil pump creates poor pressure) can destroy the lubricating oil film, wear sliding parts... Choose the appropriate gear step according to the speed and load of the vehicle if you want the best for your vehicle.

In automatic transmission vehicles, using L or 1st gear will be stronger to climb the slope than D gear is a common thought among many drivers. In fact, whether in D or L(1), the vehicle always starts in 1st gear in the AT set, the torque on the wheels when going uphill will not change when we use D or L. The purpose of the manufacturer when creating controllable gears is to allow the driver to actively change gears when using the vehicle on special roads such as steep passes, hairpin bends, etc. At that time, the vehicle needs to keep a low gear to increase stability as well as take advantage of the braking force of the engine.

This concept is only true for vehicles with cooling system problems or very old vehicles. If your vehicle's engine temperature changes according to objective conditions, it means it's time for you to have a general check of the vehicle. That's why, sometimes you don't need to worry too much when you have to use the vehicle in low gear for a long distance (pass, mountain...) but focus on controlling the vehicle and choosing the gear level so that the vehicle runs strongly and proactively at speed.

In fact, in addition to the base chemicals that clean and polish the car's paint, there is also a certain amount of abrasive powder in the car wax that wears down the polished paint layer. Polishing the car too many times when it is not really dull will cause the car's paint to wear out quickly, lose its protective layer and fade. Take care to clean the car with specialized car wash solutions, keep the paint shiny with gentle paint polishing solvents. Do not leave the car dirty for too long, causing the dirt to penetrate deep into the paint and lose its inherent shine.
