What Are the Common Knowledge About Cars?

[StBarrett]

Common knowledge about cars is as follows: Do not wash the car after exposure to the sun: After exposure, the body temperature of the car is already very high. If you wash the car with cold water at this time, it is easy to damage the paint. Do not wait until the fuel gauge light comes on to refuel: When the fuel gauge light comes on, there is too little oil left in the fuel pump, or the fuel may be exhausted, which could burn out the fuel pump. When the gasoline is insufficient, the fuel pump overheats, which affects its service life. Forgetting to release the handbrake while driving: This may cause the car to roll downhill, and at the same time, it will cause damage to the components of the brake. Not straightening the steering wheel after parking: The steering tie rod and suspension are always in a tightened state, which can easily lead to deformation over time, affecting the normal performance of the steering system. In severe cases, the vehicle may deviate from its intended path.

After driving for ten years, I realized that many common sense tips were figured out through personal experience. For example, tire pressure should be adjusted with the seasons—0.1-0.2 bar lower in summer than in winter; engine oil isn't necessarily better just because it's more expensive—you need to check the certification standards required in the manual; on rainy days, turning on the AC button for defogging is both convenient and fuel-efficient. That time I forgot to change the brake fluid and almost rear-ended someone, I learned that this stuff needs to be replaced every two years—its boiling point drops after absorbing water, which is extremely dangerous. Don't throw the maintenance manual in the glove box; the spark plug replacement mileage specified by the manufacturer is much more reliable than what repair shops suggest. Also, turning on the external air circulation clears fogged-up windows faster than internal circulation—tested and proven effective.

Many car owners often waste money unnecessarily, when basic maintenance can be done themselves. Check the oil dipstick weekly to ensure it doesn't exceed the marked line, and pay attention to the freezing point indicator on the windshield washer fluid reservoir to avoid mixing incompatible fluids. Tires must be replaced when the wear reaches the raised markers in the tread grooves, and brake pads should be prepared for replacement when they thin down to 3mm. For vehicles over five years old, special attention should be paid to the rubber bushings on the chassis, as aging and cracking can lead to uneven tire wear. Once, a customer complained about the car pulling to one side, only to find the issue was just a 0.5bar difference in tire pressure between the left and right sides. If the wipers make unusual noises, first clean the rubber blades—80% of the time, it's just sand particles stuck in them.

Only when traveling with kids do you realize how crucial safety knowledge is. The child lock must be activated, and the ISOFIX interface of the safety seat is more stable than seatbelt fixation. Adjusting the rearview mirror to just barely hide your door handle minimizes blind spots. These tips learned from parenting forums are more practical than manuals, like placing strollers horizontally in the trunk to prevent them from sliding forward during sudden braking. Remember to turn off interior lights during night driving, as windshield reflections can be deadly.
