Let's start with the fact that there is still debate among car enthusiasts about whether or not it is necessary to flush the engine before changing the oil. However, a clear answer to this question has not yet been found.
The fact is that engine flushing cannot always be considered just a preventative measure. For example, if antifreeze got into the oil, a counterfeit was accidentally poured into the engine, the engine ran for a very long time on one oil without changing, the engine overheated, the power unit has a significant mileage, exhaust gases are actively breaking into the crankcase, etc., then it is recommended to flush the engine .
At the same time, a fully operational, recently “overhauled” or relatively new internal combustion engine, which is properly and promptly serviced, may well not need additional flushing at all.
One way or another, it becomes clear that keeping the internal parts and components of the engine clean is the key to its long and uninterrupted operation. You can maintain this cleanliness in different ways, among which the use of engine flushes stands out.
Next, we will talk about what the well-known Hi-Gear engine flushes are, what features and properties the compositions of this manufacturer have, and also what results can be expected when using flushing compositions from the line of this brand.
Description, composition and properties of the product
HG2205
Hi-Gear Quick Engine Flush - a special chemical composition for radical cleaning of the system. It contains substances that form an emulsion that envelops small pieces of decay products, soot, and deposits, and thereby prevents them from coming into contact with moving parts during the procedure.
Effectively breaks down and eliminates carbon deposits. Restores the functionality of individual parts of the system. Regular use of this product allows you to do without servicing the internal combustion engine and extends its service life. Oil and filters perform their duties better after the procedure.
Intended for gasoline and diesel internal combustion engines (including turbocharged ones) with a lubrication system volume of 4-5 liters.
Why is engine cleaning necessary?
The cleaner includes petroleum distillates and functional additives, which are company secrets.
The use of soft washes in normal vehicle mode allows you to get rid of carbon deposits, carbon deposits, and varnish, improving engine performance. Also, when buying a used car with a dubious history, washing is simply necessary.
Reviews from experts emphasize the presence of alkali and alkaline earth metals in the soft wash, which indicates additional detergent additives and makes the product very highly effective.
After cleaning, access of the lubricant to hard-to-reach areas and rubbing elements becomes much easier, circulation and the ability to regulate heat are improved.
Soft cleaners have certificates that ensure stable vehicle operation in the most difficult conditions. The soft cleaner is developed based on the latest developments in this field, the special composition of which takes into account the subtleties of driving on various types of road surfaces.
Both cleaners meet the technical specifications of domestic oils and machines and are approved for use.
Instructions for use
The Hi-Gear 5-minute engine flush is used as follows:
- warm up the engine and turn it off;
- add the product to the existing oil in the system;
- start the engine and let it idle for five minutes;
- turn off the engine and drain the oil;
- change the filter and oil with new ones.
One container with the product is enough for 4-5 liters of oil. For very heavy contamination or a larger lubrication system, use 2 packs. But this volume cannot be exceeded - the seals may be damaged.
How are these cleanings different?
High Gear soft engine cleaning is intended to restore industrial parameters of diesel and gasoline engines or in cases where the history of the car is questionable or unknown.
Unlike the first type of washing, Hi Gear, a soft wear cleaner with SMT, is designed for cars with an unknown history, old, significantly dirty diesel and gasoline engines of all types, as well as for long periods of downtime, high mileage and suspicion of severe wear of engine parts, you can to say that this cleaning was created for more “neglected options”.
Hi-Gear Mild cleaner for engines with wear and tear with SMT2
Flushing is necessary in cases where the car has not been driven for several months or has a mileage of more than 70,000 km, as well as if its ownership history is unknown (when buying a used car or from a dubious seller). It is also desirable in case of significant engine contamination or signs of moderate to severe wear.
The cleaner with SMT2 works while driving, protects the engine, which as a result ensures ideal car behavior even with sudden changes in speed and driving style.
A soft cleaner for engines with wear with SMT Hi-Gear includes a new generation metal conditioner SMT2 made of synthetics, which creates the best conditions for high-quality cleaning and forms a microscopic layer on rubbing surfaces that protects the motor, preventing the formation of varnish films, soot, and carbon deposits.
SMT2 is a 100% synthetic, non-corrosive and non-flammable, non-toxic, degradable anti-friction metal conditioner using oil as a carrier. SMT2 has the greatest residual protection effect, making it possible to use the vehicle in emergency mode without lubrication. It has consistent properties thanks to a completely synthetic base.

Characteristics of Hi-Gear brand washes
At the moment, Hi-Gear soft engine flushing is one of the popular means for cleaning the engine structure from dirt and deposits. This is due not only to a good advertising campaign by the manufacturer, but also to high quality. According to reviews from car enthusiasts, Hi-Gear is one of the most effective means for cleaning the engine. But we are not going to advertise Hi-Gear products, so we will not encourage users to use this substance. Below we suggest that you familiarize yourself with the characteristics of these liquids.
Synthetic Hi-Gear with SMT
Motor fluids based on “synthetic” or “semi-synthetic” differ from “mineral water”. Both in terms of composition and additives used in MM. If you decide to switch from mineral consumables to synthetic ones, the engine must be flushed. This will allow you to clean the system not only from the dirt that collects in it, but also from the remnants of mineral MM.
Filling PS Hi-Gear into the system
Hi-Gear synthetic wash can be used. The purpose of this product is to clean the engine when switching from mineral MM to semi-synthetic. If you decide to switch from “semi-synthetics” to “synthetics”, this PS (flushing agent) is also suitable. According to representatives of the manufacturing company, the substance has a full complex effect on the internal surfaces of the engine, as well as on the motor fluid. This PS contains synthetic conditioner SMT, as a result of which the liquid helps protect the rubbing elements of the internal combustion engine system.
Hi-Gear with SMT was created to clean the lubrication system of internal combustion engines not only from carbon deposits, but also other types of deposits. As a result of the complex effect of the substance on the rubbing elements, the motorist, according to the manufacturer, will forever rid himself of problems associated with engine contamination.
Ten-minute Hi-Gear PS with SMT
If you are changing the MM, you must understand that using fresh consumables can negatively affect the functioning of the internal combustion engine. There are deposits inside the unit, and even if you fill in the highest quality MM, this will negatively affect the operation of the motor. When starting the unit, the detergent additives of fresh MM will immediately actively dissolve the existing carbon deposits. As a result of this, the consumable material will quickly darken, and all the accumulated dirt will “walk” through the system. As a result, the new oil filter will clog immediately, and the new fluid poured into the unit will lose its properties without working even 1 thousand kilometers.
Ten-minute Hi-Gear motor flush
According to the manufacturer, using a 10-minute flushing liquid will remove, if not all, but most of the deposits and carbon products. This, in turn, will improve the circulation of the working substance and heat removal from the internal combustion engine elements. In addition, according to the results of scientific research, the use of a “ten-minute” Hi-Gear with SMT will allow the formation of an oil film on the internal combustion engine components, which will prevent the appearance of dirt. Flushing will also improve the moving functions of compression and oil scraper rings.
In addition, scientific studies have confirmed that Hi-Gear with SMT is safe for rubber parts of internal combustion engines, as well as oil seals and valve stem caps. This PS contains special substances that help create an emulsion. Its purpose is to envelop sediment particles and prevent their contact with internal combustion engine components.
As in the previous case, the use of an SMT conditioner makes it possible to provide the restorative and protective functions of the rubbing elements of the motor. As for the operating features, Hi-Gear can be used in both 4-cylinder and 6- and 8-cylinder engines. If you own a car with a 4-cylinder engine and have never flushed it, then you can use PS for 8-cylinder engines.
Ten-minute hi-Gear PS with ER
The difference between this PS is that it is recommended for use in 4-cylinder internal combustion engines, in which the volume of the lubrication system does not exceed 5 liters. The manufacturer has added an ER conditioner to the structure of this PS, which makes it possible to enhance the technology for cleaning and dissolving harmful substances. The use of Hi-Gear with ER is allowed in all types of motors with any type of MM without exception.
Five Minute Cleaner for Hi-Gear Engines
Hi-Gear soft washing, according to consumer reviews, allows you to not only gently but also safely clean the engine, as well as 100% remove all harmful substances and deposits. As a result, the circulation of working fluid in the lubrication system is improved, and the system will be reliably prepared for the subsequent operation of metal conditioners.
Flushing the Hi-Gear engine is harmless to the rubber parts of the lubrication system, as well as oil seals and other elements of the unit.
Five-minute PS Hi-Gear
“Five Minute” Hi-Gear is one of the popular washes among domestic car enthusiasts. It allows you to remove deposits and accumulated dirt not only in the internal combustion engine system, but also from the crankcase pan, as a result of which there is no need to clean it when replacing the MM. When using this “five-minute solution,” according to the manufacturer, fresh MM together with the filter element will work even more efficiently. The consumable material will retain its characteristics and properties even longer, and this allows you to increase the service life of the unit as a whole.
In general, the characteristics of this PS are no different from the previous ones, “Pyatiminutka”:
- completely removes all contaminants from the system;
- prevents their formation in the future;
- restores the moving characteristics of piston rings;
- protects rubber components of internal combustion engines from harmful effects;
- is compatible with all types of MM and motors.
Soft cleaner Hi-Gear Engine Tune Up
Soft flushing of the internal combustion engine Hi-Gear Engine Tune Up makes it possible not only to prevent the appearance of carbon deposits, but also the deterioration of the unit’s performance. This soft liquid allows you to reduce the amount of harmful emissions into the atmosphere, and also increases the service life of the MM and the internal combustion engine system.
Soft flushing not only effectively cleans the entire unit, but also allows you to restore the functionality of the PCV valve. According to the manufacturer, this PS makes it possible to clean the ventilation system and eliminate the cause of the knocking of the “fingers” (hydraulic compensators), preventing them from sticking. It should also be noted the effect of PS on the piston rings - these components are completely cleaned of carbon deposits, which allows them to be restored to mobility.
It should also be emphasized that this soft washing will be more relevant when used in the engines of cars with high or medium mileage. Its use consists of adding the entire cylinder to a new MM each time it is replaced. If you are the owner of an old vehicle, the manufacturer recommends filling this PS 200 kilometers before you plan to change the MM.
Soft flushing Hi-Gear with SMT for internal combustion engines with wear
Five-minute flushing agent for Hi-Gear engines
This PS is recommended by the manufacturer for use in older engines:
- whose mileage exceeds 70 thousand km;
- in which the consumption of motor fluid is too high (due to a large amount of soot and deposits);
- noisy during operation;
- with increased fuel consumption.
In such cars, even the highest quality MMs lose their working properties after 1-2 thousand kilometers. Further use of liquid that has lost its properties reduces the service life of the motor. In such cases, the manufacturer recommends using Hi-Gear soft flush with SMT, and it must be refilled while the car is in use.
This is done in order to:
- restore the cleaning properties of motor fluid;
- clean the engine injection system while driving a car;
- restore the movable functions of the compression rings and evenly distribute the compression level across all cylinders;
- reduce the rate of gas breakthrough into the engine crankcase, which makes it possible to increase the service life of the MM and reduce the level of smoke;
- reduce noise when the engine is running;
- reduce fuel consumption;
- contribute to the restoration of the internal combustion engine by restoring idle speed.
Let’s say right away that the five types listed are not all Hi-Gear products. The main types of consumables are presented here, but the line also includes other types. They do not differ in name, but the difference is only in how dirty the engine they will be used. If you regularly wash the internal combustion engine before replacing consumables, you can use a regular five-minute PS. If the engine has not been cleaned for a long time, then you can purchase the same PS, but for more contaminated internal combustion engine systems.
Tips and tricks
So, the main properties of the most popular Hi-Gear washes were discussed above. At the same time, in the manufacturer’s catalogs you can find a large number of different flushing liquids that are distinguished by certain properties.
To summarize, the main difference between all compounds is what engine they are intended for, taking into account the degree of wear and general contamination of the internal combustion engine. In other words, for units that have not been previously washed and have a significant mileage, the same compositions are needed. However, if the engine is regularly cleaned before each oil change, a quick “five minutes” will be sufficient.
For this reason, it is necessary to select the correct flushing fluid to obtain the desired result. It is also important to understand that flushing (both High-Gear and others) in some cases can harm the engine. The fact is that the compositions are not capable of completely dissolving heavy deposits, but under the influence of washing, lumps and clots peel off from the surface of the parts.
As a result, in dirty engines there is a risk that the oil pickup screen and fine channels are literally clogged with dirt. For this reason, the engine may begin to experience oil starvation; individual parts begin to operate under dry friction conditions and quickly fail.
It should also be added that even mild washes, one way or another, still affect rubber elements. In practice, this means that after using the composition, a leak may appear due to a violation of the tightness of oil seals, gaskets, etc., and an increase in oil consumption is possible.
Another common cause of lubricant leaks is that in older engines, contaminants can act as an additional “sealant”. Moreover, after washing off such dirt, an element that has become deformed over time and has lost its elasticity (for example, an oil seal) completely ceases to perform its functions.
As a result, the part will need to be replaced, which means unscheduled engine repairs. Taking into account the above, it becomes clear that before using flushes, it is necessary to separately take into account its condition, degree of contamination and general wear.
Why do you need to flush the engine?
As is known, modern motor oils have various active properties, including detergent ones. In other words, if you use a high-quality product and replace it according to the regulations, problems with the cleanliness of the internal combustion engine should not arise, since the oil itself washes away carbon deposits and deposits.
However, if you practice switching from one oil to another, use low-grade products, exceed recommended replacement intervals, overheat the engine and the lubricant itself, operate the engine in harsh conditions, then the cleaning properties of the oil may not be sufficient.
Even if you add fresh oil with a pronounced cleaning effect, dirt and deposits will be washed away from the surfaces, but they will not be completely dissolved. As a result, fresh oil becomes dirty and quickly loses its protective properties; the circulation of washed-out clots and lumps through the lubrication system can lead to clogging of the oil filter and serious consequences for the engine.
As a result, plaque still forms on the internal surfaces, deposits accumulate, while the risks of other internal combustion engine breakdowns also increase, and the overall wear of the unit increases. To effectively remove dangerous dirt, there are two ways:
- disassembling the engine and completely cleaning the parts manually;
- use of special flushing liquids;
In turn, all flushes can be divided into full-volume flushing oils (instead of old oil, flushing liquid is poured into the system) and flushing into old oil (the composition is poured directly into the waste oil).
Let us add that each type has its own pros and cons, and is also selected in each specific case, taking into account the need for application, predicted end results, the wishes of the owner, recommendations of car service specialists, etc.
What is flushing?
Today, the domestic car market allows you to choose motor oil from different price categories and with different characteristics. Some fluids contain chemical elements that allow you to flush the internal components of the engine while it is running. As a result, there will be no carbon deposits and deposits in the system, which means that flushing the engine will not be particularly necessary.
When using lower-quality motor fluids, the likelihood of deposits and carbon deposits appearing in the engine structure increases significantly. Not every motorist knows what this means. Firstly, fuel consumption increases due to clogged elements of the injection system. Secondly, the consumption of engine oil also increases, which will have to be topped up regularly. In this case, there is only one way out - flushing the engine.
Cleaning the internal structure of the motor from carbon deposits using a brush
Engine flushing fluid is a special detergent designed to clean the internal components of the internal combustion engine. Typically, the engine flushing procedure is needed when the car owner uses different types of engine fluid. In these cases, carbon deposits appear in any case, however, in addition to this, other harmful substances appear in the engine in the form of deposits, which over time will negatively affect the operation of the unit.
Depending on the type of flushing fluid, its application may vary. Some fluids need to be added to the engine oil while the car is operating. Such substances are added periodically to the engine to prevent the formation of deposits. Other soft flushes are used when changing the oil so that harmful substances leave the system along with the “working off”. The third means are flushing liquids that need to be poured and “driven” through the system after draining the used liquid. Each engine flush has its own properties and characteristics, but how to choose what you really need?
