Flushing oil

Flushing oil - this is one of the types of products that are used to flush the internal combustion engine before the next engine oil change. With it, you can remove not only the old grease, but also the products of its decomposition, combustion and chemical decomposition, or when switching to another brand.

Such a lubricant is poured into the system after the old fluid has been drained, allowed to work for several minutes (depending on the specific brand) at idle, drained, and only after that new oil is poured, which is supposed to be driven on an ongoing basis.

Flushing oil for internal combustion engines has a "competitor" in the face of the so-called five-minute flushes. However, compared to the last ICE flushing oils have a number of advantages. The most important of them is the sparing effect of the composition on the internal combustion engine elements (including rubber seals) and their surfaces, as well as the efficiency of use. The fact is that aggressive solvents are often used in the “five-minutes”, which simply wash out any oil. In contrast, flushing compounds chemically displace used slurry and protect the oil system from wear and harmful effects.

need for flushing oil

Is flushing oil really necessary? Maybe do without it? We will immediately answer this question - yes, you can really do without it, but this is fraught with trouble for the internal combustion engine. And they are connected primarily with the fact that the new oil that will be poured into the crankcase moves with old chemical compounds that are the results of the work of the previous lubricant, as well as banal dirt, soot and other suspensions. Not only will all this immediately spoil the performance of the new oil (no matter how good it is), it will also clog, albeit slightly, the new oil filter.

It is possible to neglect the oil flushing of the internal combustion engine in the following cases:

• you are the first and only owner of the car;
• oil has always been changed on time;
• for replacement, an oil recommended by the automaker or even better was used (for example, synthetics instead of semi-synthetics);
• during the operation of the car, you never poured dubious brands of oil into the internal combustion engine or diluted the agent available there with some obscure additives, compounds, and so on.

If at least one of the above conditions is not met, then it is better to think about which flushing oil is better to use for the corresponding procedure. Especially flushing should be performed in the following cases:

• When buying a car with. After all, you do not know for sure which oil was used before by its previous owner.
• If deposits in the upper part of the internal combustion engine become excessive. This can be found out with a flashlight, shining through the neck and a little to the side.
• When switching from one type of oil to another. For example, from mineral to semi-synthetics, synthetics, and so on.
• RџSЂRё severe operating conditions motor (after high loads).
• After overhaul ICE.

And simply, if you use not the most expensive and high-quality oil, then prevention will not be superfluous. As you know, it costs less than repairs.

How to wash an internal combustion engine

Now let's move on to the question of what kind of flushing oil to use in a car. Indeed, today their choice is wide. the following is a rating of the most popular washes with a description of the characteristics and features. the list of seven remedies is based on reviews and tests from the Internet. He will help you choose the best flushing oil.

I SAY Flush

Produced in Japan and is one of the best representatives in its class. It contains hydrocarbons, organic solvents, and anti-wear additives. The main advantage of ZIC Flush is its inert chemistry. This means that it is safe for rubber and plastic parts of internal combustion engines. At the same time, it effectively flushes out old oil, carbon deposits and decomposition products of chemical compounds.

A feature of the product is its undesirable use in old ICEs with a large amount of deposits, since there is a risk of them being washed out and clogging the oil channels with them.

Sold in 4 liter cans. The price of one is about 1300 rubles. Article - 162659.

• High probability of buying a fake due to popularity.

ENEOS Flush

This flushing oil can also be attributed to the leaders. It is made in Japan. A distinctive feature of this lubricant is the fact that it not only dissolves dirt from the surface of the parts, but also leaves it in a suspended state, so that it does not re-sit on the walls of the internal combustion engine. Because of this, the life of the oil during nominal flushing is reduced. According to the instructions of the internal combustion engine, it is enough to work 10 minutes at idle. The inert compound is safe for rubber seals.

However, ENEOS Flush has a strong effect on dirt, which is why it is not advisable to use it in old and / or very dirty ICEs. This is due to the fact that exfoliated dirt can clog the oil channels. Also, this oil should not be used immediately after adding additives based on metal or ceramic complexes.

Flushing "Hado" Verylube

A good low viscosity mineral based oil. It can be used to flush not only the internal combustion engine, but also the transmission. also due to the content of a large amount of potassium hydroxide, this drug has a high base number, about 30 mgKOH/g. This makes it possible to fill the flush even in a diesel engine running on fuel with a high sulfur content. A feature of the product is the presence of a revitalizant - a product that creates protection against wear during flushing. In addition, the composition includes a complex of detergent, dispersant, antiwear and extreme pressure additives. It is absolutely safe for rubber seals.

Flushing oil with VeryLube revitalizant is poured into the engine or gearbox for 15-40 minutes of operation, depending on the degree of contamination. Due to the characteristics at which the pour point is -15°C, it can be used even in slight frost. The manufacturer claims that due to the VitaFlush technology, the flushing lubricant eliminates the “sticking” of hydraulic lifters, oil scraper and compression rings, but this fact can only be verified after application individually.

It is sold in four possible packages - a package of 2 liters, a bucket of 20 liters, barrels of 60 and 200 liters. A two-liter package, article XB20250, costs approximately 800 rubles.

ROSNEFT Express

This soft flushing oil could previously be found on sale under the THK brand (name - Promo Express) and with catalog number 40611842. Now, after the takeover of TNK by Rosneft, the oil began to be sold under the number 40811842. The composition is universal, therefore it can be used for both gasoline and diesel engines, including old and very dirty ones. The composition is not able to wash the crystallized garbage, so it works in a gentle mode.

The tool can be used to clean the internal combustion engine after working in difficult conditions, with overloads and overheating. it can also be filled in after using low-quality (or mistakenly filled) oil in the internal combustion engine.

Sold in canisters of 3,5 liters. The price of a package as of the end of 2021 is 650 rubles. Article - 40811842.

Lukoil flushing oil

Good domestic oil, which is intended not only for AvtoVAZ cars, but also for foreign cars. It can be conditionally attributed to the middle price class. The car wash oil is based on a mineral base, as well as detergent additives designed for a gentle regime to remove contaminants from the internal combustion engine. Oil flushing is universal, it can be used in both gasoline and diesel engines.

the basic recommendation from the manufacturer is regular use when changing the oil. That is, if the internal combustion engine has never been washed from soot and slag, then Luxoil will not wash it off for sure.

According to the instructions, to achieve the effect, you need 20 minutes of quiet operation of the started internal combustion engine. It is worth noting that the manufacturer does not declare anti-seize components in the composition, therefore it does not protect against premature wear of internal combustion engine parts, which also once again confirms that the duration of operation and idle speed cannot be exceeded.

It is packaged in 4-liter canisters, the average price of which is about 830 rubles. Article - 19465.

Since the creation of this rating (2018), as of the end of 2021, the cost of the above flushing oils has increased by an average of 40%. There are also several folk remedies for flushing. One of them is commonplace diesel fuel, because in its flushing properties it is similar to flushing oil, it is just as oily and liquid. The algorithm for its use is identical. It is poured into the crankcase instead of the main oil, after which the internal combustion engine idles for several minutes. In ancient times, when there were no complex flushing compounds, it was a very popular flushing agent. However ineffective as flushing oil for diesel internal combustion engines, because it has a composition similar to deposits.

How to use flushing oil

The unequivocal answer to the question of how to use flushing oil is indicated it's in the instructions for it.. Usually it can be read directly on the packaging or in the accompanying documentation. However, in most cases, the algorithm is the same, and resembles an oil change in an internal combustion engine. In general terms, the process consists in draining the old oil, pouring flushing lubricant instead, running the internal combustion engine on it for 10-20 minutes and draining the resulting slurry.

Ideally, after draining the flushing oil, you need to use a special compressor or vacuum pump, with which you can remove oil residues from the crankcase (usually after draining it remains about 200 ... 300 grams).

Hack and predictor Aviator

Flushing oil is a very useful tool with which you can extend the life of both the internal combustion engine and engine oil. The flushing process is especially recommended when buying an old car, switching to a new type of oil, after significant loads on the internal combustion engine, when it is heavily clogged. As for the choice of one or another oil, they are approximately the same in terms of characteristics.

Therefore, base your choice on the ratio of price, quality and its availability on the shelves. Do not neglect the reviews of various brands, because sometimes they are not always suitable specifically for your case. And try to make purchases in trusted stores so as not to run into fake goods.
