«The debate about the need for engine flushing has recently intensified. And all due to the fact that more and more used cars are appearing on the market than new ones. Panacea? Or harm? Are there many engine oil system flushes that are actually effective? Let's deal with everything in order.
»
The wash is poured into the oil before changing, mixed with the lubricant that has already exhausted its resource, and allowed to work for some more time (most often 5...10 minutes). Then the resulting liquid is drained and fresh oil is poured into the engine. All of these products contain cleaning additives similar to those found in regular motor oil or exclusively solvents. It is this fact that causes many to doubt whether such a composition will be able to wash away the sludge, oil and fuel combustion products that have accumulated over the years, in a few minutes or at least a couple of days of work.
You can flush the engine with several means - flushing oil, oil or a liquid with which you need to drive for a while. But the most popular remedy is a 5-minute engine flush . Since the last two drugs are used most often - due to their ease of use, we will consider their effectiveness in more detail.
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.
Flushing or flushing oil?
Engine flushing fluids appeared in the late 1960s and early 1970s simultaneously in the USSR and the West.
In the Soviet Union, internal combustion engine flushing was invented to clean low-speed diesel locomotive engines, and the product for this procedure itself was mineral oil with detergent additives. This method was transferred to passenger vehicles without any changes. Flushing oils sold very successfully.
But this method had significant drawbacks:
- Quite a lot of non-drainable oil residues for flushing settled inside the engine.
- Manufacturers skimped on the components of the composition, because the products posed a danger to highly accelerated engines
Western companies have chosen a different path. Economists considered the use of oil products for flushing unprofitable: they had to pay for the oil, as well as for its disposal. Therefore, we developed a special technology for using flushing liquids, which today we know as express flushing.
Hi-Gear Mild Engine Cleaner
For cars with an unclear history (when purchasing a used car), for old, very dirty engines, the manufacturer recommends mild cleaners. The precise operating principle of the additives makes it possible to wash away dirt deposits not in large fragments, but in the form of a finely dispersed phase that does not pose a danger to engine parts. This provides deep cleansing.
Hi-Gear soft engine flush effectively cleans the crankcase ventilation system and engine lubrication, improves the performance of the PCV valve. Purification has a unique technology that promotes the consolidation of contaminants in the form of a finely dispersed phase.
The action of the additive occurs while the engine is running, while driving.

Instructions for using Hi-Gear soft wash
- flushing is added to fresh lubricant after each shift;
- For engines with high mileage and high oil burns, it is recommended to add another can 100–200 km before the oil change.
Before using the cleaner, you should warm up the engine and let it idle.
What means are used to flush the engine?
Despite the fact that most washes act similarly, they are still divided into several classes. Among them:
- "Five Minutes" . As a rule, they are based on an organic solvent, which allows you to quickly and rapidly wash away dirt and deposits. The advantage of such products is their high speed of action. Disadvantages - along with dirt, the “five-minute” can wash away the lubricant from working mechanical pairs. As a result, scratches may appear on the parts. Therefore, such drugs can only be used when the engine is idling.
- Soft engine flushes . They are added to the oil approximately 100...300 kilometers before the scheduled oil change. They act more gently than previous products, since their base is created from calcium sulfonates (something like soap and similar detergents). In addition to the base, the composition includes dispersing additives.
- A mixture of the first two options . These can be a variety of compositions containing both solvents and detergent components with additives. As practice shows, universal tools are not as good as special ones tailored to solve a specific problem.
There is another class of rinses, which can conditionally be called folk, but they also belong to the “hard” class. For decades, before the advent of modern chemicals, motorists added various solvents, including acetone or solvent . This solution does exist, but with some limitations:
- The effect of such funds is very limited in time. They are allowed to work literally for 3…5 minutes. Naturally, during this time they will only be able to wash off surface deposits.
- Under no circumstances should you increase the speed when there is such a flush in the engine!
As an example, we list several popular compounds belonging to certain classes (naturally, their true number is many times greater).
- “Five Minutes” - Hi-Gear-Motor Flush HG2214, ER PROFESSIONAL motor Flush P023RU, Hi-Gear Motor Flush HG2204 and “EL TRANS Cleaner Oil System”.
- Long-acting products - Liqui Moly Oil-Schlamm-Spulung.
- Universal products - COMMA Petrol Engine, Liqui Moly Engine Flush and Liqui Moly Pro-Line Motor Spulung.
Each of the listed rinses has its own characteristics of composition and use, so it is necessary to read the instructions!
Remember that all of the listed remedies are preventative and are not intended to decarbonize the engine. And also that before filling in new permanent oil, it is advisable to blow out the system using a compressor or use a vacuum pumping device in order to remove all remaining oil mixture in the engine (after traditional draining, about 200...300 grams always remain).
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.

Instructions for using Hi-Gear soft wash with wear with SMT2
Treatment of a used or worn engine:
- add 1 can of flushing per 4–5 liters of engine lubricant 1500–2000 kilometers after replacing the engine lubricant;
- 1 more can is poured in 150–200 kilometers before the upcoming lubricant change.
There is an alternative option that involves treating a new engine or engine without wear: add 1 can of cleaner 150–200 kilometers before the next lubricant change.
How does flushing work?
Quick (five-minute) flushing of the engine lubrication system works using a fairly simple method. This composition is poured into the lubrication system, after which the engine should run for about 5 - 10 minutes, and the liquid resulting from mixing is drained. The composition of the product for flushing into the oil before changing includes a large (so-called shock) dose of detergent components . Which in a short time can wash away old dirt, scale, deposits and other debris. This is evidenced by numerous engine flush tests. Their results can be found in sufficient quantities on forums and various resources on the Internet.
Sometimes on the Internet you can find conflicting reviews about a particular product, the essence of which boils down to a negative effect. However, this attitude is often the result of improper application of flushing. If the product contains aggressive substances, then with prolonged exposure to rubber seals there is a risk of damage to the latter. And this leads to an emergency situation. Therefore, before using this or that product, you must carefully read the instructions for its use and act in accordance with it.
Looking ahead, it is worth noting that the effect of using such rinses is indeed observed, but it is not as fantastic as their manufacturers write in the instructions . Therefore, the appropriateness of use remains questionable.
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”.
Advantages and disadvantages
The universal cleaning formula makes it possible to use the composition with any type of lubricant in any engine, even those operating with turbocharging.
Advantages of Hi Gear soft engine flushing:
- increasing the cleaning properties of motor oil;
- increasing and equalizing pressure in the cylinders;
- reduction of smoke and toxicity of exhaust gases;
- reducing or eliminating the knock of hydraulic compensators;
- reduction in fuel and engine oil consumption;
- increasing the power and throttle response of a car engine;
- restoration of uniform idle speed;
- cleaning piston rings from carbon deposits, restoring their mobility and fit;
- restoring the operation of the positive crankcase ventilation system valve and cleaning the PCV;
- reduction in the passage of gases into the engine crankcase, which leads to dilution and oxidation of the oil, decomposition of additives in the lubricant;
- absence of substances toxic to the engine, flushing can be present in the lubricant constantly;
- consolidation of contaminants in the oil pan thanks to unique technology.
No deficiencies found.
When is it necessary to flush the oil system?
- Before changing the oil
- After engine decoking
- If the quality of fuel and engine oil is not ideal
- If you forget to change your engine oil on time
- When switching from one class of lubricating fluid to another
- If the engine often operates in extreme conditions
- If oil consumption increases, engine interruptions begin
Flushing the oil system is a modern and understandable technology that allows for the prevention of the formation of harmful deposits. Thanks to this, the new lubricant will last longer, and the car’s oil system will be reliably protected.
