1. Add a mat on the seat
★Event replay: Summer is coming, and it's really uncomfortable to sit for a long time. Regardless of leather seats or knitted interiors, they are prone to sweating, not only affecting the image, but also making it difficult to concentrate on driving. It is better to add a bamboo mat to sit and cool down, and the price is not expensive. On less hot days, there is no need to turn on the air conditioner, and the fuel consumption is also reduced.

Are you afraid that you won't be able to throw yourself out when braking? The friction of this type of mat is small, whether it is accelerating or braking, it is easy for the body to slide when braking, and the protective ability of the seat belt is also reduced to a minimum. So just turn on the air conditioner when it's hot. Compared with the small amount of money you save, you should put safety first.
2. The more engine oil you add, the better.
★Event replay: It's time to change the engine oil. Some car owners want to be more considerate of their cars, so they fill up the engine oil. They believe that adding more oil will better lubricate the engine, and it can also reduce the frequency of oil replenishment, saving trouble and money.

Expert opinion
If there is too much engine oil, it will increase the workload inside the engine. When the engine is working, the crankshaft and connecting rod will produce violent agitation, which will not only increase the internal power loss of the engine, but also increase fuel consumption. The increased oil splashed on the cylinder wall will easily cause oil burning, resulting in poor engine lubrication. The amount of engine oil should be controlled within an appropriate range, between the upper and lower lines of the oil dipstick.
3. Leaving perfume indiscriminately in the car
★Event replay: The smell in the car is always a bit cold and unpopular, so drivers like to put some car perfume, air freshener and the like in the car. The car smells great and the bad smell is gone.

Expert opinion
Air fresheners are also synthesized from various chemical ingredients such as ether and essence. They do not decompose harmful gases. They only cover up odors by emitting aromas and "dilute" odors by confusing people's sense of smell. The gases produced after the chemical decomposition of these substances in the air are themselves air pollutants, which in turn aggravates the air pollution in the car. Long-term use can cause adverse irritation to the human body, and low-quality fragrances can also cause harm to the human nervous system.
The chemical components of fragrance can be absorbed into the human body through the mouth, nose and skin. These ingredients can reach all parts of the body through blood circulation. Sensitive people are prone to headaches (especially migraines), sneezing, watery eyes, difficulty breathing, dizziness, sore throat, chest tightness, hyperactivity and other symptoms.
4. Add mushroom heads
★Replay of the incident: The car felt lackluster after being driven for a long time. If more air could enter the engine to allow the gasoline to burn more fully, wouldn't the power be improved? So some car owners had the air intake system repaired. The modification you take for granted: Just install a "mushroom head" directly on the air inlet. I heard that this can increase the air intake of the car. The engine will "eat" more, and the power will naturally be enhanced. And the price is cheap, only 300~500 yuan, so why not.

Expert opinion
It has been said in advertisements that people will get bloated easily if they eat too much, and the same is true for cars. The scientific name of "Winter Mushroom Head" is high-flow style. It is a high-performance air filter. In theory, it can indeed increase the air flow in the engine, make the combustion in the engine compartment more complete, and improve the power performance. However, for the air in the north that contains a lot of fine dust, increasing the air intake will also bring more fine dust into the cylinder, causing early wear of the engine, but affecting the engine's power performance.
5. Cars hit by the scorching sun
★Event replay: Spring is here, can summer be far behind? In summer, some car owners impose their habit of taking a shower on their cars. After driving for a day, I gave it a cold shower to cool down. Most car owners will find that after taking a shower, their car will stop eating immediately. When the car was taken to the repair shop, the owner still said plausibly: "I did it for its own good!"

You also know that when a person rushes into the cold water, he will tremble and shiver, etc. The car cannot speak, so you just torment it like this. Thermal expansion and contraction are the simplest physical principles. After exposure to the sun and driving, the temperature of the car's paint surface and engine will be very high. At this time, you have to clean it inside and out. Good guy, the paint surface will be tortured by you. At most, it will peel off paint or something in the future, but the engine will stop immediately and will not cost you thousands of dollars. Return to work.
