Wuling 4s to change the oil, you must buy a deep oil change

1. Thank you! Deep oil replacement: In addition to releasing the oil from the oil sup shell, use the suction method to extract the old oil as much as possible, so that the addition of new oil will also increase (if it is not drained cleanly, the general 4L oil will not be used up).

2. The meaning of deep oil change in the s store is: in addition to releasing the oil from the oil sup, use the suction method to extract the old oil as much as possible, so that the addition of new oil will also increase.Release the original old oil in the engine through gravity oil release until the gravity oil release cannot continue to release the old oil.

3. It is very important to choose a reasonable oil change cycle, otherwise if you change the oil in advance, it will feel like a waste of money; changing the oil too late will affect your car. The oil change cycle is affected by many factors, including mileage, oil type, driving habits, road conditions, etc.

4. However, car owners don't need to pay too much attention to changing the new engine oil. When buying a new car, try not to remove the oil sin casually. Dismantling the oil salp is a major operation. It will not have a great impact on the operation of the vehicle. Pumping oil is better than draining oil.

What should I pay attention to when replacing engine oil? How long is it appropriate to clean up?

When changing the oil, be sure to replace the oil filter.Because the old oil filter may be blocked by impurities, the blocked filter will slow down the flow of oil and reduce the lubrication of the engine. The old oil remaining in the filter will reduce the quality of the new oil.

When adding lubricating oil, it is appropriate to keep the scale slightly lower than the oil scale. In addition, it is necessary to master the model, season, climate, engine displacement, technical performance and many other factors of the engine oil.

Precautions for changing car oil: Oil is not only for wear resistance. Oil is as important to the engine as blood is to the heart. The engine is the heart of the car. There are many metal surfaces that rub against each other in the engine. These parts move fast and have poor environment, and the working temperature can reach 400℃ to 600℃.

A sufficiently thick oil film separates the surface of the relatively sliding parts, so as to reduce wear.Cooling: The oil can bring heat back to the fuel tank and then emit it into the air to help the water tank cool the engine.

Therefore, changing the oil in time is the best care for the engine. Oil change cycle When buying a car, car manufacturers will attach a car repair and maintenance manual. The manual lists the oil change mileage/oil change cycle of the vehicle, and most cars are 5000-10000 kilometers.

What does deep oil change in 4s store mean

Deep oil change means that after gravity releases the oil, the remaining oil at the bottom of the fuel tank is extracted by professional equipment, so that the fuel tank is completely drained and new oil is added. Benefits of deep oil change: Thoroughly remove impurities such as oil sludge remaining in the fuel tank and lubrication system, so as to improve the lubrication effect.Extend the service life of the new oil change.

Engine deep oil change means that after the engine oil is released through gravity, the residual oil in the bottom of the fuel tank is extracted with professional equipment to achieve the purpose of completely emptying the fuel tank and re-adding new oil. Benefits of deep oil change: Thoroughly clean the oil tank and residual sludge and other impurities in the lubrication system to improve the lubrication effect.

Engine deep oil change means that after the engine oil is discharged by gravity, the residual oil at the bottom of the fuel tank is discharged with professional equipment to achieve the purpose of completely emptying the fuel tank and re-adding new oil. Benefits of deep oil change: Thoroughly clean the residual oil sludge and other impurities in the oil tank and lubrication system to improve the lubrication effect.

According to the information released by Pacific Automobile Network, deep oil change refers to completely draining the old oil and then adding new oil.This method can remove dirt and impurities in the engine more thoroughly, but the corresponding cost will be higher.

Generally speaking, the maintenance item of replacing the whole car oil is called major maintenance, including engine oil, brake fluid, booster fluid, transmission fluid and antifreeze. Except for engine oil, other oils can be changed every three years or 60,000 kilometers. They can be changed together. There is no need to replace them too early, especially the transmission oil.

In-depth maintenance is the in-depth inspection and maintenance of the car. Replace the three-filter air filter, air conditioner filter and gasoline filter. Oil circuit maintenance, cleaning the fuel nozzle, replacing the spark plug, and cleaning the throttle valve. Change the brake fluid, antifreeze and power steering fluid. Do a brake maintenance, check the thickness of the brake pad, and replace it directly when it is thin.

Is the deep oil change cleaning kit useful

It is necessary to reduce the fuel consumption of the car. Brake disc cleaner can quickly clean the brake disc, oil stains on the brake hub and brake pad dust, maintain good heat dissipation of the brake disc, eliminate brake noise, promote uniform braking, and prevent the production of asbestos powder. It is a good helper for the maintenance and maintenance of automobile brake discs.

There is no need to do this kind of cleaning. Generally, the repaired scrapped car is deeply cleaned, because the old oil is completely cured after being parked for a long time. Doing this is mainly about the cost of consumables. Of course, it's not bad if a million-level luxury car drives tens of thousands of kilometers. Excessive maintenance of a car of more than 100,000 yuan will only increase the cost of using the car.

The oil doctor fuel system 6 sets are useful. This can not only help suppress the generation of carbon accumulation, but if used regularly, the oil line is clean without carbon accumulation, and it will also improve the power and reduce the effect of fuel consumption.

[Pacific Automobile Network] Deep oil change is necessary. After the engine is used for a period of time, more glue and carbon will remain inside. If the oil is slightly changed, these sediments will not be discharged. The noise of the vehicle has increased, the power has become worse, and the fuel consumption has increased.In the long run, the service life of the engine will be greatly reduced.

Of course, it is useful, but the effect is relatively limited. The internal cleaning agent of the engine can clean the residual dirty oil sludge in the engine oil channel, and to a certain extent, it can also clean the carbon accumulation in the piston ring and ring groove, which has a practical maintenance effect on the engine.

It's not necessary. It's all to fool money to replace the oil, oil filter, clean the air filter, and air conditioning filter. When the whole car is checked, inspected and maintained, they will be more serious. By the way, they will be close to the masters, and it's still beneficial to be familiar with each other.
