How to maintain car oil in summer

1. Secondly, the boiling point of antifreeze is above 120℃, while the boiling point of water is only 100℃. The use of antifreeze can prevent Love cars in summer.Finally, replacing antifreeze with water is easy to generate scale, so it needs to be replaced frequently, and there is no such concern when using antifreeze.

2. The brake fluid should not be too full. The maintenance mileage of the brake fluid is long, and it is usually checked after driving 50,000 kilometers to 20,000 kilometers. However, the liquid level of the brake fluid will decrease with the wear of the brake pad, and the external high temperature will also affect the brake fluid level. The amount of brake fluid will change according to the degree of wear of the brake pads.

3. Using antifreeze can prevent cars from "boiling" in summer. Finally, replacing antifreeze with water is easy to produce scale and needs to be replaced frequently, but using antifreeze does not have this problem.

4. Eight precautions for summer maintenance: (April, May, June, two o'clock every month) Protect the paint surface: the temperature rises in summer, the sun often explodes in the sun, and the paint of the car is obviously not good.It is recommended to make a layer of glaze or coating on the paint surface and apply a layer of "crystal protective clothing" on the paint surface.

How much is appropriate to refuel the car

It is more appropriate to refuel the car to 60% to 70% of the fuel tank capacity, which can not only reduce the weight of the vehicle, but also avoid the harm caused by full oil. The volume indicated by the fuel tank is not the actual maximum volume, but the maximum reasonable volume. Ordinary fuel tanks can add 10%~15% more diesel in addition to the marked volume.

If it's not summer, it can be filled up every time. If it's summer, add 3/4 each time. The fuel tank of the car is not completely sealed. There is a carbon tank in the fuel tank. When the pressure of the fuel tank is too high, the solenoid valve of the carbon tank opens so that the gasoline steam in the fuel tank is absorbed by the carbon tank.The fuel tank is generally made of plastic, and the fixed position of the fuel tank is generally close to the rear suspension.

If it's not in summer, you can fill it up every time. If it's summer, you can add 3/4 position at a time. The fuel tank of the car is not completely sealed. There is a carbon tank in the fuel tank. When the pressure of the fuel tank is too high, the solenoid valve of the carbon tank will open, so that the gasoline vapor in the fuel tank can be absorbed by the carbon tank.

Car manufacturers recommend that the capacity of the fuel tank is 60 liters. Considering the expansion coefficient of the oil, it is reasonable to store less than 60 liters of oil, which can provide enough empty space for fuel expansion caused by temperature rise and ensure the safety of the fuel tank during use. First of all, the accuracy of the fuel cannot be judged by the rated capacity of the fuel tank.

yuan, then it will cost about 345 yuan to fill up this fuel tank.Then we can just tell the gas station directly: "Please add 300 yuan of gasoline". Let's calculate: 300 yuan is just equivalent to the amount of about 45L of gasoline, which is about 90% of the total capacity of 50L. This is a completely reliable and safe amount of filling.

How to choose engine oil for car maintenance? Only choose the right, not expensive

1. Choose oil according to the engine type. If you are a turbocharged engine, it is recommended to choose fully synthetic or semi-synthetic oil. Good fluidity is more conducive to engine heat dissipation; if you are a naturally aspirated engine, it is recommended to choose semi-synthetic or mineral oil.

2. How to choose the right oil How to choose the right car oil?The first thing to consider when choosing an oil is the viscosity of the oil. Choose the most appropriate one according to the viscosity of the oil required by the manufacturer. There is nothing more suitable than this. There are specific requirements in the general maintenance manual or instruction manual.

3. The method of selecting engine oil for car maintenance is as follows: choose engine oil produced by big brands or large factories: such as Shell, Mobil, Casto, Gartex, Total, BP, Shengpai, Fox, GS domestic big brands include Kunlun, Great Wall, Longpan.
