Oil is the most important oil in a car, equivalent to the blood of the human body. Different cars use standard oils and have different replacement cycles. Some drivers don't know the car and don't know when to change the oil. If the frequency of oil changes is too high, it will not only hurt the car, but also waste money. The general oil change time is about 6-8 months, semi-synthetic oil is exchanged for 8000 kg, and full synthetic oil is changed for 10,000 kg. Some drivers use semi-synthetic oil. The car has been driving for 8 months, but the distance of the car is less than 6,000 kilometers, so in this case, should the oil be changed?
The role of oil: oil is mineral oil, plays a role in lubrication, but also can dissipate heat, parts cleaning, rust, anti-corrosion. In a word, the effect of oil on the engine is very large, and the quality of the oil will affect the experience of the car. As a consumable, the use time of motor oil will gradually decrease, the life of semi-synthetic oil will also be shortened, the quality of full synthetic oil will become better, and the use time will become longer. If the oil is not changed for a long time, it will deteriorate and cannot lubricate, rust, corrosion and heat dissipation on the engine, resulting in engine problems. Some owners do not change the oil for a long time, or use counterfeit and inferior oil. This oil does not provide sufficient lubrication for the engine and can cause a lot of wear to the engine.
When should I change the oil? Some owners spent more than 8 months to reach the oil change cycle after refueling, but the distance traveled by the vehicle has not yet reached this number. At this time, should the oil be replaced? The answer is that the oil should be changed. Semi-synthetic oils degrade after 6 months, and fully synthetic oils deteriorate in quality after 8 months, so it takes some time to change the oil. The parameters deteriorate after the oil deteriorates, so it can still be used, but it is not recommended that the owner continue to use it. Some car owners may say that their car has not been oiled for a year, the driving distance is less than 8,000 kilometers, and the vehicle has no problems. This is because the owner of the car for a long time at a low speed, a short distance, the engine did not reach a state of intense operation, so even if it is not seriously worn, the owner does not feel anything.
If we often drive at high speed and the engine is driving at the limit, then if the oil is not replaced for 8 months, it will have a great impact on the engine. Please take a look at the car's repair manual. The time of use of the oil is detailed. Manufacturers do not recommend that car owners use spoiled oil. After the oil reaches the service time, the owner must extract part of the oil for inspection. Spoiled oil has the potential to emulsify, and lubricity, wear resistance, and corrosion resistance are reduced. If the owner notices that the oil on the fuel gauge is light or paste-like, this gasoline has undergone severe emulsification and must be replaced immediately. If you know that the oil on the dial gauge is black and brown, and tiny particles appear, then the oil will deteriorate and precipitate. If this oil is continued, these tiny particles will wear out the engine.
Editor's Note: When the oil reaches the replacement period, even if the driving distance has not yet been reached, it is recommended that the owner change the oil as soon as possible. Spoiled oil can have an adverse effect on the engine, and this loss is irreversible.
