Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.
Internal combustion engines are subject to increased stress in the form of friction and temperature. When a development forms on the walls of the cylinder, the engine begins to 'eat' oil. At the same time, compression is reduced and power is lost. To eliminate this effect, special additives are used in the lubricant, which are introduced into the inner surfaces and perform a restorative function. As a result, the wear of the cylinders and rings decreases, the thrust increases, and the consumption of fuels and lubricants decreases. This review will show you the top rated engine oil additives that have received positive customer reviews and have good performance.

Liqui moly ceratec
Rating: 4.9
The product from the Liqui Moly company is the leader among additives in motor lubricants. Ceratec is available in a 300 ml bottle. A German manufacturer has created an additive with a synthetic organic molybdenum complex. It also contains microceramics. This combination forms a strong film on the metal surfaces of the internal combustion engine, which does not collapse from strong friction and high temperatures. The additive helps to reduce stress and protects motor parts from abrasion. With it, the oil resource is also extended up to 12,000 km, which means that maintenance can be performed less frequently.
Our experts ranked this additive first in the review because it markedly improves compression. This is confirmed by numerous positive reviews from car owners. After using the additive in engine oil, the pressure in the cylinders can rise to 1.0-1.5 bar. This is especially true for 'tired' ICEs, which have serious performance. If it is not possible to overhaul the engine now, then such an additive will ensure its operation for another 50,000 km.
Advantages
- dynamics is significantly improved;
- the motor starts to work softer, there is no roar at high speeds;
- reduced fuel consumption;
- the exhaust gas emission is less toxic.
disadvantages
- high price;
- you can get fake;
- before use, you need to rinse with MotorClean, the price of which is also high.
Bardahl full metal
Rating: 4.8
We gave the second place to the additive Bardahl. It does not have solid particles, but after 'fusion' with the metal it becomes no less strong. The product is sold in a 400 ml bottle and is a concentrate. The contents are 6 times lighter than steel. Suitable for gasoline and diesel power plants. In the reviews, drivers like that it can be used regardless of the type of engine oil the owner is used to (mineral, synthetic or blended).
This additive is the best because it is 10 times denser than steel. Hydrocarbon molecules penetrate cracks and fill voids with themselves. An ultra-strong coating is created that not only restores compression, but also acts as an additional lubricant for the piston rings. As a result, when starting the engine, while it has not yet reached the operating temperature, the surfaces of the cylinders wear out less. If you are one of those who do not like to wait in the morning for the internal combustion engine to warm up and are ready to go right away, then such an additive will help protect the engine from excessive wear.
Advantages
- neutralizes microleaks of engine oil into the combustion chamber;
- restores the tightness of the pistons;
- Polar Plus protective film promotes additional lubrication;
- does not clog the engine;
- the oil filter passes the substance well.
disadvantages
- high price;
- 400 ml is required for 6 liters of lubricant – if you have less, you will have to calculate the proportion yourself.
RUTEC Pit-Stop 40 XXL (P-20-40 / 75)
Rating: 4.7
To increase compression, there is a good additive from the domestic manufacturer Rutec. It is designed for four-stroke internal combustion engines of passenger cars without strict requirements for the type of fuel (diesel / gasoline) and the type of fuels and lubricants. The product is available in a 0.75 ml plastic container, and one package is enough to process the internal surfaces of a motor with a volume of 2.5 to 5.0 liters. Therefore, owners of medium-sized cars will have enough bottle for two times, and owners of powerful SUVs will not have to buy two containers. Reviews show that the additive doubles the resource of the power plant, but if you start adding it when black smoke comes out of the exhaust pipe, then the substance will no longer help.
This additive is the best because it can be used as a preventive measure. The manufacturer allows it to be added to the oil after 40,000 mileage. The additive in the motor does not clog the filter, penetrates well into the metal and does not harm a relatively new internal combustion engine. But its use immediately protects the power unit from wear and tear, so that overhaul is not required even after 300,000 km of run (provided that the substance is added every 20,000-30,000 km).
Advantages
- reduces fuel consumption;
- improves dynamics;
- eliminates combustion of fuels and lubricants;
- increases the environmental friendliness of the exhaust.
disadvantages
- requires frequent use for maximum effect;
- only for engines of passenger cars;
- difficult to buy;
- high price.
SMT Oil Treatment
Rating: 4.5
The additive is developed on the basis of the second generation metal conditioner SMT. The synthetic substance tolerates high temperatures and friction well. It reduces the load on engine parts and doubles the life of the unit. Drivers in the reviews like the extreme pressure properties of the additive, so that the operation of the motor with worn rings and walls does not worsen its condition. The engine oil does not foam or oxidize. Thanks to the seals from the additive in the cylinders, the breakthrough of heated gases into the crankcase is excluded. Drivers feel the savings in fuel consumption and the increase in compression even in cases of sunken piston rings, therefore, the product simultaneously plays the role of decoking.
The additive is the best in price when compared to similar products from other manufacturers. This will help save money and extend the life of the motor. We also suggest paying attention to this product for taxi owners. In the constant struggle to reduce the cost of the car, but keep it in good condition, it is the perfect compromise.
Advantages
- good price;
- can be bought in many specialized stores;
- improves throttle response;
- reduced acoustic noise;
- Eliminates the break in the oil layer between the mating parts.
disadvantages
- the effect is enough for 5000 km, after which reapplication is required;
- you can buy a fake.
The best additives in gasoline
Suprotec Active Plus
Rating: 4.6
This additive is produced in a small tube and is intended for gasoline engines, as well as power units with gas equipment. The agent is not added to oil, but to gasoline. This can be done before refueling at a gas station, or when self-supplying fuel from a canister. It is allowed to use it already on internal combustion engines with a range of 50,000 km or more. The additive helps to increase power and reduce fuel consumption.
The product was recognized by us as the best due to its versatility. This additive can be poured not only into the engine, but also added to the gearbox. The composition helps to fill all the gaps, which reduces noise. The film still formed reliably protects the power unit. Judging by the reviews, thanks to the additive, the engine can even run 30 minutes without oil if it flows out through the punctured oil pan. The product is optimal for heavily worn piston systems where lubrication is often required. If you miss a level (there is nowhere to buy, a long trip and the stock is over), then the additive will help you get to the nearest settlement.
Advantages
- on cold there is no knock from hydraulic lifters;
- reduced gasoline consumption;
- an increase in power is felt;
- reduction of vibration.
disadvantages
- not suitable for diesel – different combustion temperature;
- necessary thorough mixing with fuel.
