Which flushing oil to choose? It depends on what engine oil you use and how dirty your engine is. All washings are divided into two types.

soft additives. It is simply mineral oil with a very low viscosity. It contains a huge amount of detergent and extreme pressure additives. Sodium and potassium acids neutralize the acidic environment from oil mining. The product is sold in large canisters.

Often, soft flushes are poured into the engine, after which it is washed at idle for 10-15 minutes. During flushing, do not load the power unit.Otherwise, the protective oil film enveloping the engine elements will be destroyed.

Soft oil mixes with the remains of the engine, neutralizes the acidic environment, washes away carbon deposits and deposits. Then it merges together with all contaminants, and fresh engine oil is poured into the engine.

Five minutes. This is a more aggressive type of washes, including solvents, solvents, calcium sulfonates. The product is often sold in cans. It is added to the already used oil, and then drained along with all the accumulated dirt.

If soft flushes can be used for a long period, then five minutes should not be left in the engine for a long time. In addition, their more aggressive formulation can damage rubber seals.

Optimum price/quality ratio

The cost of a 4-liter canister is 800 rubles. harmoniously balanced by a good washing quality. This is the best option for washing out oil and dirt residues after decarbonization.

  • Average cost: 863 rubles.
  • Country: USA/Russia
  • Volume: 4 l
  • Shelf life: 60 months
  • Application: gasoline engines and transmissions of passenger cars
  • Purpose: extending the life of motors and gearboxes

Oil from the American company Delfin Industry, formerly known under the Luxoil brand. The product broke into our market and competed with domestic oils and Western-made fluids. All thanks to compliance with ISO 9001 standards. If you want something cheaper, then there is a domestic analogue of Rosneft MPA-2. The composition is the same, but only for a more budgetary amount. The Russian analogue is suitable only for domestic cars.The engine of a foreign car will not tolerate too active exposure to the Russian package of detergent additives.

Pros and cons
  • Smooth transition to new oil
  • Reasonable cost
  • Long lasting result (does not darken about 1000 km)
  • Quiet engine operation
  • Used after engine decoking
  • Requires regular use

The best cleaning of old oil

The mineral base of the second group and 1% additives (there are 12% in engine oil) thoroughly rinse out exfoliated dirt and remnants of old engine oil.

  • Average cost: 1000 rubles.
  • Country: Japan
  • Volume: 4 l
  • Shelf life: 60 months
  • Application: gasoline engines, diesel units, manual transmissions of foreign and domestic cars
  • Purpose: smooth transition to new oil, cleaning of carbon deposits and sludge, prevention for oil channels

Japanese oil 10-minute: 10 minutes of idling - and all the dirt falls into suspension. But such an effective remedy is not for everyone. If you have a very clogged old motor, loose pieces will clog the system. In addition, you should not use oil if you have just "healed" the engine with ceramic or metal additives. All extended teeth and surfaces will dissolve in the cleansing oil. Remember the cost too! If the product is cheaper than 1000 rubles, most likely you have a fake. Japanese quality costs a little more!

Pros and cons
  • Pour point -43 degrees
  • low viscosity
  • Cleans well all the cracks and gaps
  • Quick oil warm-up
  • Poor package of additives
  • Price

The most effective additive

Works well with engine oil, completely dissolving in it. Holds all impurities in suspension.

  • Average cost: 836 rubles.
  • Country: Belgium
  • Volume: 0.325 l
  • Shelf life: 60 months
  • Application: oil system, engine crankcases of cars, SUVs, ATVs, mopeds (differentials, transfer cases, manual transmissions)
  • Purpose: extreme pressure additives, flushing of sludge and carbon deposits, gentle cleaning of piston and hydraulic pushers

The oil belongs to a professional line and is even suitable for flushing manual transmissions. Contains anti-seize additives. Detergent additives effectively clean piston rings, oil passages and crankcase walls. The washed deposits are held in suspension, so fresh engine oil will stay clean longer. Although this is not a soft flush, many drivers like to drive 100 kilometers on it before filling in engine fluid. Such trips significantly reduce the noise level of the power unit and prevent sticking of the hydraulic valve lifters.

Pros and cons
  • Long lasting wash with long lasting results
  • Quiet engine operation
  • Soft operation of the injector
  • Consumption reduction
  • Requires up to 3 liters for a thorough flush
  • Requires mechanical descaling

Pros and cons

Accounted for 626 reviews from resources: Ozon, Yandex.Market, Online Trade, PartReview
The most economical

For 5 liters of engine oil, you need only 300 ml. For comparison, 4 liters of MPA 2 are poured immediately instead of oil. And the effect is the same.

  • Average cost: 717 rubles.
  • Country: Germany
  • Volume: 0.3 l
  • Shelf life: 60 months
  • Application: engines of passenger cars and commercial vehicles
  • Purpose: extending the service life and increasing the dynamics of motors, decoking

One of the best representatives of five-minute flush mixtures for engines, which are used in a quiet driving mode or with a predominant stay in traffic jams. 300 ml of liquid is enough for 5 liters of engine oil.It is used with diesel and gasoline units. The additive not only effectively cleans engine components from varnish and sludge deposits, but also extends the life of the oil itself. And the liquid gently cleans the rubber seals without reacting with the rubber compound. The extreme pressure properties of the additive do not allow it to be used with power plants with oil bath clutches (most often these are motorcycles).

Pros and cons
  • German product quality
  • Can be used after 2-3 oil changes
  • No unpleasant odor
  • Reduced consumption
  • High cost per 300 ml
  • There are fakes (instead of a sticker print)

  • Volume: 3/3.5/4.5/30/216 l.
  • Shelf life: 60 months
  • Application: car engines
  • Purpose: extending the life of the motor, protecting elements from corrosion

Although Spectrol Motor Cleaner is called an oil, it is actually just a liquid. It is found on the shelves of car dealerships in almost every city, even if the choice is not very good. And the plus is not only this - the liquid is suitable for any type of engine. And it will also be effective if you switch from mineral water or semi-synthetics to synthetics. Of course, you can get a fake (there are practically no distinctive markings on the bottle indicating that this is the original), but this is unlikely to harm the engine. In extreme cases, you can buy another canister and repeat the flushing procedure.

Pros and cons
  • Low cost
  • Can be used to flush the generator
  • Silent operation of the internal combustion engine
  • Removes non-draining oil residue

  • Average cost: 1036 rubles.
  • Country: USA
  • Volume: 0.444 l
  • Shelf life: 60 months
  • Application: fuel system, diesel and gasoline engines of passenger cars
  • Purpose: optimization of the operation of friction pairs with increased clearances, reduction of dynamic loads from motor elements

Synthetic composition recommended for use before pouring synthetics or semi-synthetics into the motor. If mineral oil has been used previously, the detergent additive will remove the remaining mineral oil so that it does not mix with the new working fluid. But, it goes without saying, the oil will clean the engine elements from soot and deposits. Another plus of the composition is the absolute safety of rubber products, rings, seals. The tool cleans the piston rings from coke well. Not every flush can cope with this task. And the SMT metal conditioner additionally forms a protective film on the surface of rubbing parts.

Pros and cons
  • Reduced motor wear
  • Noise reduction
  • Easy cold start
  • Reduced idle consumption
  • A large number of fakes
  • Permanently breaks down worn gaskets
