Do I need to do engine oil cleaning for car maintenance?

1. Is the cleaning agent harmful to the engine?

Long-term and high-speed operation of the engine during the addition of cleaning agent will cause wear and tear on the engine, but as long as the cleaning technician follows the cleaning process, there will be absolutely no long-term and high-speed operation.

In other words, it is harmless to clean the engine in a reliable place.

2. Is it necessary to clean the engine oil passage?

It is necessary. The main function of motor oil is lubrication, lubrication, lubrication. Cleaning things about machine oil can be dry, but no cleaner specialty.

As an aside, any product has *** and poor quality, and it is usually not bad to choose a big brand, because a big brand generally does not risk smashing its own signboard. I only choose engine cleaners from Shell and Castrol.

Is it to clean the sludge from the engine oil or to clean the gasoline oil circuit of the engine? If it is to clean the sludge, it doesn't hurt to do it, the use of fully synthetic engine oil theoretically does not need to do, good engine oil will have the ability to clean, the general larger manufacturers and the original factory are OK, do not worry too much, that is, dozens of yuan less than 100 yuan, that is, after the old oil is released, add the cleaning agent to let the engine run for a while and then release it, and then add new oil, its practical ordinary mineral oil can be replaced, add a tank of cheap mineral oil for dozens of dollars to run for a while and then put it out, and then add new oil, The effect is similar to that of adding cleaning agents, as long as the quality of the oil is not particularly poor, there is no need to do it, and it is the same, dozens of dollars can have a real effect of doing it and there is no harm <>

There is no need to do engine cleaning!

1. We know that the main function of engine cleaning and maintenance is to clean the carbon deposits inside the engine. And its use is also relatively simple, the general engine cleaning rotten return maintenance is a set of two bottles: engine system cleaning agent and engine system protector.

Before our car is serviced, the mechanic will pour the engine cleaner into the engine first. Then start the vehicle and idle for 5-10 minutes. The engine protectant is added to the engine before the new oil is added.

In this way, the entire process of engine cleaning has been completed.

2. Do you have any doubts about whether this kind of cleaning can clean the carbon deposits?

The answer is: no!

Because after long-term use, the internal carbon deposits have been firmly stuck to the inside of the cylinder. This kind of cleaning will not clean up these carbon deposits, and the most it will clean up is the relatively soft sludge inside the engine. As for carbon deposits, it basically won't have much effect!

3. Is it necessary for us to clean in this case? Personally, I don't think it's necessary!

We know that the carbon deposits generated before the vehicle is bought for 2-30,000 kilometers are very small. Many car owners who don't understand the car often do all kinds of cleaning kits when the car is insured for the second or 30,000 kilometers.

4. What should we do?

Start with the oil filter! Engine oil is the most critical medium for the production of carbon deposits, especially fake engine oil, inferior engine oil. When such oil is added to your car, it will not only produce a lot of carbon deposits, but also damage the internal parts of the engine due to poor lubrication.

There is also the machine filter, which is the same as the engine oil, and the inferior oil filtration effect is extremely poor. The oil pan with impurities will pass through the filter to the cylinder head, causing severe wear or blocking the oil passage! In the long run, mechanical parts such as camshafts will break.

Since we're so willing to spend money on maintaining our own cars, let's start with the basics. We can choose high-quality synthetic engine oil when maintaining the engine oil. Try not to use mineral oil!

High-quality synthetic motor oils inherently have the effect of cleaning carbon deposits and resisting wear.

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!

Car maintenance: Do I need to clean the engine after changing the oil? How do you do that?

Now the weather is getting day by day, and many people who know how to drive know that when the season is replaced, you need to take special care of the car, especially the maintenance of the engine, which is the top priority.

The engine is the most important part of the car, and the interior is full of machines, through thousands of small parts, to assist in starting the engine, so as to make the car walk. If any of these parts were to stop, we would have to walk to work. One of the most common ways to maintain these small parts in the winter is to change the oil.

And basically every maintenance to change the oil, the purpose of changing the oil is to make the lubrication system can better serve the engine, better lubrication and better cooling, while changing the oil, the carbon deposits in the lubrication system can be excluded from the car, so as to better protect the engine.

Now, there are many repair shops and 4S shops that advise car owners to clean the engine when they change the engine oil, is this work necessary? First of all, let's understand what engine cleaning is. Secondly, we also need to understand what the purpose of cleaning the engine is.

Engine cleaning refers to the cleaning of the inside of the engine

In fact, our engine oil itself has a certain cleaning effect, and each oil change can actually be regarded as an internal cleaning of the engine. However, the oil will form carbon deposits inside the engine, which can be done every time the engine oil is changed, so the internal cleaning of the engine refers to the addition of carbon deposition cleaner to clean the carbon deposition in addition to the conventional oil replacement, so as to ensure the better operation of the engine.

The cleaning method is also very simple, that is, pour the carbon deposition cleaner into the oil port before changing the oil, and then start the engine for 5-10 minutes to let the carbon deposition detergent and the old engine oil fully integrate in the engine, and then release the old engine oil so that it is completed, the time is not very long, **discrimination is also good, but do you need to do it every time?

As mentioned earlier, engine cleaning is to clean carbon deposits, so it is basically not necessary to do this for new cars or cars with relatively short mileage, generally speaking, more than 15,000 kilometers can be considered to operate like this, or the vehicle feels a little idle and shakes, and the oil consumption is abnormal, you can consider cleaning it, and other times depending on your economic affordability, in general, there is no harm in doing this thing.

However, it is best to buy a brand to change the oil, and the oil filter is also replaced at the same time. When the oil is too old, the noise and vibration of the engine increases significantly, and it is time to pay attention to the mileage of your car. After the oil change, the fuel consumption has a fixed increase after the oil change, and if you have been using a certain grade of engine oil, you should not change it frequently.
