Notice to car owners, the car common sense you insist on is not necessarily right!

Car seats cannot be covered with cushions

Many people saycarSeatCar seat cushions should not be used. First, because the car seats are specially designed by the manufacturer based on ergonomics, it is uncomfortable to sit on a seat cushion; second, the exterior car seat cushions will hinder the seat.airbagNormal ejection is not conducive to safety.

And I think these rhetoric are missing a premise, such as woven seats, I am afraid that it is not resistant to dirt, and it will not look good if it is dirty. It is normal to put on a fake leather cushion; but what about airbags? If this car has two airbags in total, where are the extra airbags rushing out of the seat?

The higher the gasoline mark, the better for the car

Generally, high-grade cars are equipped with high-grade gasoline, and high-grade cars are more expensive, so some car owners worship high-grade cars too much. In fact, this is completely unnecessary. The amount of oil marked by the car is determined by the compression ratio of the engine. The owner only needs to add the gasoline mark allowed by the vehicle.

Fill up the engine oil

When some car owners go to a 4S shop for maintenance, they always want to fill their car with oil. It seems that if you add less, you will lose money; or car owners who are burning oil also want to add more oil for fear that the oil is not enough. In fact, this is not right. If you add too much oil, the crank connecting rod will produce huge agitation when the engine is working, which will innocently increase the internal power loss of the engine and increase the oil on the cylinder wall, which will increase the oil burning phenomenon.

Manual transmission vehicles must be more fuel efficient than automatic transmission vehicles

It turns out that in the past, manual transmission cars are indeed more fuel-efficient than automatic transmission cars, but now and then, the previous automatic transmission technology is not mature, and it is normal to be less fuel-efficient than manual transmission. But as the automatic transmission technology becomes more mature, many automatic transmission models are more fuel-efficient than manual transmission vehicles.

Previous knowledge of various models

In the past, it was said that Japanese cars had big stuffing and thin skin and were unsafe; American cars were gastronomical; autonomous cars were not of good quality; if you still think so, then you are out.

Those who don't have anti-collision steel beams are hooligans

In fact, the anti-collision steel beam can effectively reduce the damage of the car only when the car is in a slight collision. In a high-speed collision, the main role is still the car's longitudinal beam, which can effectively absorb the energy generated by the car's collision.

Adding mineral oil must be more cost-effective than fully synthetic oil

Everyone knows that fully synthetic motor oil is much better than mineral motor oil. The obvious reason is, because fully synthetic motor oil is much more expensive than mineral motor oil, so I think that using mineral oil for your broken car is just fine, saving money! But is this really cost-effective?

It is conservatively estimated that mineral oil is maintained at 5000 kilometers and fully synthetic engine oil is maintained at 10000 kilometers. In this way, if you add fully synthetic engine oil, although the engine oil is more expensive, the cost of mineral engine oil is less and the maintenance man-hour cost is less. Counting the protective effects of the two engine oils on the engine, do you still think it is cost-effective?
