1. Engine oil
The lubricating oil manufacturer recommends that the engine oil change cycle is 5000 kilometers or half a year, which has become a customary rule.
But the answer to the oil replacement cycle is very simple. Just look at the "Maintenance Manual" ("Owner's Manual") delivered by the original car.
If some friends want to maintain it by themselves, and the replacement oil is also purchased by themselves, then you need to distinguish the replacement cycle according to the type of oil purchased.
Different types of engine oil change intervals are different, there are mainly the following three:
Fully synthetic engine oil replacement cycle: 10,000 kilometers or 1 year;
Semi-synthetic oil replacement cycle: 7,500 kilometers or 6 months;
Mineral oil replacement cycle: 5000 kilometers or 3 months.
It should be noted that in unconventional driving conditions, the replacement cycle should be reduced.
The unconventional driving state actually refers to the non-uniform speed driving of the car. For example, in a city, because of traffic jams or traffic lights, cars go and stop every time. Another example is short-distance driving, driving to work, the one-way distance is only six or seven kilometers, and the car stops before it heats up completely. These situations are called unconventional driving conditions.
The shelf life of tires is 5 years. If the owner of the car's tire maintenance is in place, and the road conditions are good, and the tire wear is not obvious, then the owner can replace the tires of the car within 5 years. The total mileage of tires cannot exceed 100,000 kilometers.
If the tire wears to the limit mark, even if the mileage does not exceed 100,000 kilometers, it needs to be replaced. For example, the tread pattern depth is less than 1.6 mm, the occurrence of tread cracks, tread bulge, lack of tread rubber, uneven wear, corrosion by chemicals, and tires that have been pierced by foreign bodies many times.
3. Filter element
The filter element includes an oil filter element, an air filter element and an air conditioner filter element.
The engine is equipped with an organic oil filter element in the lubrication system to prevent impurities from being mixed into the oil to cause oxidation and produce gum and sludge to block the oil circuit, so as to ensure the cleanliness of the oil circuit. The replacement cycle of the oil filter element is 5000 kilometers, and it is replaced at the same time as the oil.
The main function of the air filter is to block the dust and particles inhaled by the engine during the intake process. If the filter is not cleaned and replaced for a long time, it will not function.
If dust is sucked into the engine, it will cause abnormal wear of the cylinder wall. Therefore, the air filter is best replaced every 10,000 kilometers.
Air conditioning filter:
The working principle of the air conditioning filter element is similar to that of the air filter element, which is to ensure that the car air conditioner is turned on and can breathe fresh air at the same time.
The air-conditioning filter element should also be replaced regularly. The easiest way to identify it is to smell the wind blowing from the exhaust vent when using the air conditioner. If there is a peculiar smell or there is a lot of dust in the wind, it must be cleaned, maintained and replaced.
4. Brake pads
In the brake system of a car, the brake pad is the most critical safety part. The working principle of the brake pad is mainly friction. The friction between the brake pad and the brake disc and the tire and the ground is used to stop the car.
A good brake pad is the protector of people and cars. Under normal circumstances, the thickness of a brand new brake pad is about 1.5cm, if your brake pad thickness is less than 0.5cm, you need to replace it immediately.
Unlike other accessories, the wiper replacement time is uncertain. According to the quality of the wiper, the use environment, and the degree of maintenance, the replacement time of the wiper is different. The most important indicator is actually to see if there are water marks on your wiper when you use it.
It is recommended to replace the wiper once every six months to a year to avoid damage to the car glass.
The spark plug directly affects the engine's acceleration performance and fuel consumption performance. When choosing a spark plug, first determine the model and heat level of your car.
It is very simple to judge the maintenance period of the spark plug. When you feel that the engine power is insufficient while driving, you should check and maintain it once; when you find that your car has idling jitter, starting difficulties, or engine performance degradation, in most cases, you need to replace the spark plug.
According to different materials, general recommendations are: replacement of ordinary spark plugs at 30,000 km; replacement of platinum spark plugs at 60,000 km; replacement of iridium spark plugs at 80,000 km.
