The quality of engine oil directly affects the life of the car, as well as the safety of engine parts. If the oil comes across low-quality, or the owner of the car forgets to replace it in time, then slag and pollution begin to be deposited on the motor, which inevitably worsen the performance of the car. In this case, experts recommend using flushing, which effectively cleans the internal parts. You can read about how to use flushing oil, which manufacturers to trust, what features different brands of this product have in this article.

Why flushing is needed

Modern engine oils are formulated with high quality additives designed to effectively clean the engine, protect it from deposits and oxidation, and extend engine life. Why then use washes? Some people think it's just another marketing ploy. ToUnfortunately, in reality, many drivers do not follow the recommendations of manufacturers, which leads to a reduced life of the car. Flushing provides an opportunity to correct flaws in maintenance and improve car performance.

At first glance, flush oil looks exactly like engine oil. But there are several differences between them. It contains much more detergent additives than conventional grease. Flushing should never be filled in as a permanent liquid for internal combustion engines. The fact is that after a short operation of the motor, all the slags and deposits that have accumulated on it fall into the flush, which makes it unsuitable for further use. Therefore, after 10-15 minutes, the flushing oil is drained and standard grease is poured. In what cases do experts still recommend doing this?

When to flush the engine

Flushing oil is not always necessary. For example, if you change the fluid in your car in a timely manner and use the product of trusted companies, then you can do without washing the engine. But this procedure should be carried out in the following cases:

• You don't remember what oil was put into the engine last time. This situation is quite common. Sometimes, due to heavy employment, motorists forget which brand or type of engine oil they used. If you fill in a different type of lubricant, then a mixture of additives may occur, and oil components will settle on the walls of the engine.
• If the car is over 10 years old and has a motor system that is not in perfect condition, then ratherIn total, a lot of pollution has accumulated on the walls of the internal combustion engine. For proper operation, you need to clean them and change the oil regularly in the future. A well cared for machine will last much longer.
• If you are experimenting with a car and “testing” different types of oils on it, if you notice a deterioration in engine performance (it has become noisier and power has decreased), then it is better to change the oil after using a flush.
• A defective oil filter can also contribute to severe engine contamination. Sometimes in car services, the masters forget to change it and leave the old one. In this case, it does not perform its functions, so the engine oil quickly becomes unusable.

Flushing process

How to use engine flush oil? Not everyone can perform this procedure, as it requires certain skills and knowledge. If you decide to flush the engine yourself, then you need to follow the following procedure:

• First you need to drain the used oil. The engine of the machine must be warmed up before starting work, and it is better to have a large container and rags on hand.
• Next, the plug on the crankcase, located at the bottom of the pallet, is unscrewed. If the oil is completely dark in color, it means that it was of poor quality or has not been changed for too long.
• The crankcase needs to be screwed back and flushed. Usually it takes the same amount as regular oil. If you are not sure about the required amount, then you can find information on the required amountin the instruction manual. The upper mark of the filled liquid should be at the “max” level.
• The engine should run with flush oil for about 10-15 minutes at idle. During this time, detergent additives will be able to clean it of all toxins.
• At the end of the flushing process, drain the used fluid and fill in new engine oil. By the quality of the drained liquid, you can see how badly the engine of your car was contaminated.

Types of flushing oils

Today there are several types of washes on the market, which differ in price and composition.

1. Five-minute fluids. As the name implies, these products do not require much time - it is enough to pour them into the engine for five minutes, and you can remove them without even starting the engine. Five-minute flushes consist of powerful solvents and aggressive additives that can remove contaminants in a few minutes. Such oils are made on the basis of diesel fuel.
2. Classic washes. They differ from conventional motor oils only in additives that contain more detergent components. You can not find flushes in every store, so it’s better to check availability in advance.

Pros of Flushing

On the Internet you can find many opinions on whether to use flushing oils. Let's look at all the pros and cons in more detail. Rinsing is required. In some cases, it can be a real salvation for the engine. For example, if you bought a car with your hands or notsure of the quality of the previous brand of engine oil, then flushing is mandatory. It contains alkaline additives that dissolve deposits and wash them out of the engine. But if you change the oil in the engine on time and use quality products, then you are already doing enough to clean your engine. In this case, flushing is not recommended, as they have a number of disadvantages.

Cons

Even experts say that flushing should be used only in extreme cases. Why? Because, basically, ordinary motor oil is enough, which already performs the functions of cleaning the motor. If you decide to use a flush, then it is better not to buy 5-minute products that contain aggressive ingredients. Regular flushing oil will do the job much better. Some motorists claim that about 10% of the used flush remains in the engine and does not affect the composition of the new filled oil in the best way. It turns out a mixture that is not at all suitable in composition and characteristics for your car. Therefore, before buying a flush, carefully weigh the pros and cons or consult with the service station master.

How much does flushing cost

Prices for such a tool may be different. For example, one of the most popular Lukoil flushing oils (4 liters) costs about 350 rubles. Five-minute cleansers can be bought for 250-300 rubles. Oils from more well-known European companies are a little more expensive - about 600 rubles. Compared to motoroils, flushing is not so expensive. If we take into account the cost of a new engine oil, filter and the replacement work itself, then the amount is quite impressive. Therefore, you need to approach the engine cleaning procedure wisely.

Rating

Which flush oil is better to choose? To answer this question, you need to highlight all types of washes available for purchase, evaluate their chemical composition and quality.

• Motorists, without saying a word, consider Lukoil flushing oil to be the best of its kind. The article of this product in online stores: 19465. This is a high quality lubricant, which contains a mineral liquid in the base. Among its positive qualities: dispersion, good solubility and excellent washing characteristics. A package of flushing oil 4 liters costs about 300 rubles.
• The next well-known flush from TNK is a universal remedy that can neutralize contaminants and additives from another brand of oil. The oil can be used for all types of engines: old and new, diesel and gasoline. The fact is that TNK washing contains no aggressive components that affect crystallized deposits. They often close microcracks and corrosion, which are very common in old motors. Therefore, the use of TNK flush is quite safe and does not harm the machine.
• Engine flush from Shell Helix has long been recognized as one of the best, but very expensive. The goods are sold in small packages of half a liter, and one such bottle costs 370 rubles. Therefore, the method of cleaning the engine withShell cannot be called economical. Flushing oil part number depends on the online store.
• Flushing "Rosneft" is made on the basis of mineral oils with detergent additives. One package of 4 liters will cost 500 rubles.
• If you decide to use five-minute oil, then Liqui Moly is the leader in this area. For a small jar of 300 ml, you will have to pay 350 rubles. But this amount of funds is enough to get rid of pollution inside the internal combustion engine.

Flushing "Lukoil"

Let's take a closer look at the most popular product from the list - flushing oil "Lukoil" (4 l). Why is it so attractive to car owners?

Flushing oil "Lukoil" (4 l) is a special liquid based on mineral components, whose viscosity is four times less than the consistency of a conventional motor lubricant. This allows flushing to penetrate even into the farthest corners of the engine, cleaning it of contaminants. The composition includes additives ZDDP, which reduce the level of wear of older engines. They also contain calcium, which helps to neutralize the acidic environment that forms inside the motor. Feedback from motorists proves that this technical fluid, when used correctly, can extend the life of the car for a long time. But if you are not confident in your abilities, then it is better to give the car for “washing” to the service station master.

Motorists' opinions

Mostly very good reviews of flushing oils. 4L as reckonconsumers, - the most convenient volume in use. You can purchase such a container and use it more than once. Car owners note improved engine performance. Flushing oil cleans old deposits and by-products, so often just black liquid is poured into the sump. But experienced drivers do not recommend cleaning the engine with synthetic fluids too often. So you will only wash off the protective lubricating film on the engine parts. What other advice can experienced professionals give?

Recommendations

Specialists say that the use of flushes is justified only in extreme cases. For example, if you forgot what oil you used last time, or you bought a used car from your hands. In this case, you can take a chance and use flushing oil.

What are the dangers of these funds? They contain chemical compounds and additives that can affect the "heart" of the car is not always positive. Another disadvantage is that detergent residues can react with regular motor oil and change its properties for the worse. Do not trust advertising that says that without the use of flushing, changing engine oil does not make sense. Your excessive scrupulousness in this matter can only make things worse, because ordinary lubricants are already based on protective and detergent components.

Problem Prevention

To avoid breakdowns and costly repairs, car owners need tofollow a few simple rules:

• Change the oil on time. It is recommended to do this every 10-12 thousand kilometers. But if your car is older than 10 years, then you can do this a little more often: every 5-6 thousand km. This frequent replacement will save your engine from waste and keep it in excellent condition.
• Use products of well-known companies. World famous brands are oriented to high standards and undergo numerous tests, so you can be sure of their high quality.
• Follow the manufacturer's recommendations regarding the type and viscosity of the oil. For the most correct operation of the internal combustion engine, it is necessary to use thinner oils in summer, and thicker ones in winter. Each car has an instruction manual that lists the recommended brand and base oil (synthetic or semi-synthetic). Compliance with these conditions has a positive effect on the operation of the car.

Results

Flushing oil can and should be used, but only for certain indications. In other cases, you can do with a regular oil change. This will be enough to extend the life of your car.
