How to change the oil in the car without cleaning the engine?

There is no need to clean the engine for 10,000 kilometers of the new car, and the cleaning of the engine throttle injector is carried out every 20,000 kilometers and the protection of the engine can be carried out every time the oil is changed Brake oil The steering machine has the Gearbox oil is generally 40,000 kilometers for a job change, Of course, it is also this time to clean and protect These cleanings you do belong to the in-depth maintenance series It is more thorough and professional than conventional maintenance, so it is correspondingly more expensive But it is good for the entire parts and service life of the car. This is a basic process, and the specific amount of time depends on the working conditions of the car, and the necessary operations are carried out according to the actual situation. When engine oil works in a high-temperature environment, it will inevitably suffer from oxidation and pollution. Therefore, after a period of use, the engine will produce carbon deposits, oil stains, and gum.

These contaminants will reduce or even block some of the engine's delicate oil circuits, so that the oil cannot properly lubricate and protect the various parts of the engine. When the car starts, especially when it starts cold, it is easy to wear the engine because the oil cannot provide effective protection for the engine in time. In addition, the adhesion of oil sludge to the cylinder wall will also increase friction, resulting in fuel consumption.

At the same time, dirty oil can cause insufficient oil pressure, which can lead to valve failure with hydraulic tappets, causing abnormal engine noise, unstable idling, and reduced engine power. Therefore, for some cars whose engines have not been cleaned and maintained for a long time, have a long oil change cycle, and have poor road conditions, a simple oil change can no longer keep the engine interior clean, so engine cleaning is required. For normal vehicles, when driving to 45,000 kilometers, it is also necessary to clean and maintain the engine.

How to clean: Engine cleaning, which is divided into two parts: external cleaning and internal cleaning. The general steps for external cleaning are:

Flameout; Wait for the engine to cool down; Wrap the distributor, ignition coil and other devices with plastic film to prevent water ingress; Cleaning with a special cleaning agent; After cleaning, use a hair dryer to dry the wire joints. Internal cleaning is the key to engine cleaning. Generally, the disassembly-free cleaning method is used, which can be carried out when the oil is changed.

The general procedure is: pour the engine professional cleaner into the oil filler, mix it with the old engine oil, and idle for 20 to 30 minutes before the oil is discharged. Today's professional engine cleaners can make engine cleaning easy, and you can see the effect of increasing engine power in a short time, and you can also hear the engine sound taper.

My car is an imported German GT Magic Red engine oil, and I haven't done engine cleaning. When you change it, you just ask the auto repair shop to drain the old engine oil and make a new song. Because GT is the base oil of PAO, the cleaning performance is good, after the first pot is washed a bunch of stains and sludge down, the engine is cleaner than cleaning, the car has no noise at all, the power response is very fast, and it can run 15,000 kilometers and then replace.

I think it is necessary to clean the engine because there may be a lot of carbon deposits in the engine, and cleaning the engine can remove the carbon deposits.

I don't think it's necessary, because cleaning the engine can easily damage the sensors on the surface, which is not worth the cost.

I don't think it's necessary to clean the engine, because the engine is generally just floating dust, which does not affect the normal operation.

If needed, when changing the oil, buy a bottle of engine cleaner and add it, idle it for a few minutes, then let go of the old oil and add new oil. Otherwise, residual oil will reduce the effectiveness of synthetic oil.

Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

Flush the urinal after defecation without using a toilet brush"Cylinder block", and don't even give"Cylinder block"Varnishing and waxing, you can also continue to use, and this is a problem. Or pull dozens of times to brush the cylinder, pull hundreds of times to wax once. The metaphor is vulgar, the reason is simple, don't listen to fools.

Nearly 90,000 kilometers of Audi S5, try to use new engine oil maintenance, and replace the new air grid, air conditioning grid, clean the engine internal carbon deposits and oil circuit carbon deposits.

The purse is bulging, and it doesn't hurt to clean it, in the past, the oil channel was cleaned with gasoline and kerosene oil.

Beat the bucket of diesel, drain the oil, pour it in, and idle for 5 minutes. Absolutely clean!

Basically, you need to change the oil every time you maintain it. The purpose of an oil change is to allow the lubrication system to better serve the engine, better lubricate and cool, and at the same time to remove carbon deposits from the lubrication system from the vehicle, thus better protecting the engine.

Nowadays, there are many repair shops and 4S shops, and it is recommended that car owners clean the engine when changing the oil. Is this necessary? First of all, we need to know what engine cleaning is. Secondly, we also need to know what the purpose of cleaning the engine is.

The so-called engine cleaning refers to the cleaning of the inside of the engine. In fact, our engine oil itself has a certain cleaning function, and each oil change can actually be regarded as an internal cleaning of the engine. But the oil can create carbon deposits inside the engine, which is not possible with every oil change.

Therefore, the internal cleaning of the engine means that in addition to the regular oil change, the carbon deposits are cleaned at the same time by adding a carbon deposition cleaner to ensure that the engine runs better.

The cleaning method is also very simple, that is, before changing the oil, pour the carbon deposition cleaner into the oil port, and then start the engine for 5-10 minutes, so that the carbon deposition cleaner and the old oil in the engine are fully mixed, and then release the old oil. It's done. It's not very long, and it's not bad to discriminate, but does it need to be done every time?

As I mentioned earlier, engine cleaning is to clean up carbon deposits, so it's almost unnecessary for new cars or cars with short mileage. Generally speaking, this operation can be considered when the vehicle has traveled more than 15,000 kilometers, or the vehicle feels a little idle and shaky, and the fuel consumption is abnormal. Consider cleaning it off, and other times it depends on what you can afford.

In general, it is harmless to do so.

If you need it, when you change the oil, buy a bottle of engine cleaner and add it, idle it for a few minutes, then let go of the old engine oil, and then add new engine oil. Otherwise, residual oil will reduce the effectiveness of synthetic oil.

Engine oil, that is, engine lubricant, English name: engine oil. The density is about to lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the blood of the car.

Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of imitation sail trap lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil. The engine is the heart of the car, and there are many metal surfaces in the engine that are ready for friction and movement, and these parts move fast and in poor environments, and can operate at temperatures of 400°C to 600°C.

The new technology transforms natural gas into crystal-pure, fully synthetic base oils, on which is added with unique powered cleaning technology to create lubricants with superior cleaning protection. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life. (Photo by photo:.)

<> "There is no need to clean the engine when changing the oil. Because the engine oil itself has a certain cleaning function, every time the oil is changed, it can actually be regarded as an inland macro part cleaning of the engine.

The role of motor oil is as follows:

Cleaning effect: The engine oil has a good fluidity, and in the process of flowing, it can wash off the dirt on the surface of the parts, which can make the parts filled with oil work better.

Lubrication: The more common role of engine oil is that it can play the role of lubrication, which can make the two sliding parts run without friction and can be smoother, so when the oil volume is insufficient, it should be replaced in time.

Cooling effect: The reason why engine oil can protect the engine is also because the engine oil has a good cooling effect, which can absorb heat and help heat dissipation when the engine is running at high temperatures, and can make the car run well.

Shock absorption: Because the oil can lubricate the bearing, it can play a role in shock absorption.

Anti-rust and anti-corrosion: The premature aging of engine oil can have such an effect because it has adsorption and can adsorb harmful gases.

We basically know that the driving distance of a car is certain. According to the regulations, the oil needs to be changed every 5000-12 thousand kilometers driven, and the maintenance period of the engine oil is estimated according to the use of the vehicle. During the maintenance period, it is necessary to change the oil, oil filter, air filter, etc.

However, a very large number of car owners do not understand the importance of cleaning the appearance of the engine. They think that the engine compartment is usually invisible, and if it is dirty, it doesn't matter, there is no need to clean it, as long as the oil and the machine are filtered and maintained. However, this thinking is wrong.

Because the cleanliness of the engine compartment also determines the safety of the vehicle. Open the hood and you'll notice a stain on the surface of the engine. These stains can affect engine heat dissipation, which in turn can lead to high engine compartment temperatures.

This not only affects the life cycle of the engine, but also accelerates the aging of internal components such as wiring harnesses, posing a safety hazard. In addition, there are things similar to oil sludge in the cabin, which are attached to the ** bundle and hose, and the high temperature of the cabin in summer is easy to cause spontaneous combustion. Therefore, most good repair shops, after changing the engine oil, most of the time will have the car owner clean the appearance of the engine.

The dust in the cabin is first blown off using an air pump, and then sprayed with the same cleaning agent that cleans the engine. For example, it is necessary to scrub the surface of the line, plastic and rubber, battery connectors, exposed metal parts, etc. in all directions. This keeps the cabin clean and dissipates the heat from the engine faster!

In this way, the engine is fully maintained from the inside out, giving people a feeling of being reborn, even when driving. Therefore, we advocate regular cleaning of the exterior of the engine and maintaining a good engine working environment, which is also very beneficial to the safety of the vehicle.
