The quality of the engine oil used directly affects the life of the car's engine. These compounds prevent friction of parts of the power plant, reduce wear. Some compositions also allow you to reduce fuel consumption. The demand for Valvoline Synpower 5W-30 oil among motorists in the CIS countries is average. Here are just those drivers who have poured this mixture into the engine at least once, give preference to it in the future.

A few words about the brand

Valvoline is unique. The fact is that this company was the first in the world to offer various lubricants for engines. They were made from crude oil. It happened in 1873. Brand oils have long remained the undisputed leaders of the industry. They were used for civil and military vehicles. Often, the compositions of the company were also used for aircraft engines. Now the production of oils is concentrated in the USA and the Netherlands. The brand does not sell licenses to third-party companies, so the lubricants of this company are highly stablequality.

Nature oil

Valvoline Synpower 5W-30 motor oil is exclusively synthetic in nature. A variety of crude oil hydrocracking products are used as the base composition. To improve the technical properties of the oil, manufacturers have increased the proportion of modifying additives. This made it possible to significantly expand the range of application of the composition.

For which engines and machines

Valvoline Synpower 5W-30 is suitable for diesel and gasoline engines. According to the API standard, this composition is assigned the index SL / CF. Mixtures of this category can be used even on power plants, additionally equipped with a turbocharger. The presented composition is suitable for cars, trucks and SUVs.

Seasonality

According to the classification of the Society of Automotive Engineers of America (SAE), the presented oil belongs to the category of all-weather. The fluidity of the composition remains stable over the widest temperature range. According to the SAE 5W-30 index for Valvoline Synpower, we can say that the presented mixture is able to maintain the viscosity necessary to start the engine even at -25 degrees Celsius. At the same time, you can pump the composition through the system up to -35 degrees.

Manufacturers managed to achieve such indicators thanks to the active use of various polymer additives. Their mechanism of action is simple. When the temperature drops, the macromolecules of the substance coil into a spiral, which makes it possible to reduce the viscosity of the composition and maintain its fluidity. During heatingthe reverse process takes place. It should be noted that polymer macromolecules are gradually destroyed from constant folding and unfolding.

In the composition of this lubricant, manufacturers have also increased the proportion of pour point depressants. The use of polymers of methacrylic acid made it possible to significantly reduce the curing temperature. Presented oil freezes at -45 degrees Celsius. The rate of paraffin crystallization drops significantly.

Remove carbon deposits

Valvoline Synpower FE 5W-30 effectively and quickly removes carbon deposits from the internal surfaces of the power plant. For this, special detergent additives were introduced into the composition of the mixture. Sulfonates of magnesium, calcium and barium are absorbed on the surface of the soot and prevent its precipitation. At the same time, they destroy already formed deposits. As a result, the quality of the power plant is improved. The fact is that with an increase in the amount of soot, the vibration of the engine increases and a characteristic knock occurs. A decrease in the effective volume of the inner chamber leads to a sharp decrease in motor power. At the same time, a certain part of the fuel does not burn out in the chamber, but enters the exhaust system directly.

Coot formation is most common in diesel engines. It's just that the fuel for these power plants is characterized by an increased amount of sulfur compounds, which increase the ash number.

Lifetime

The total duration of use of a lubricant directly affects its resistance to oxidativeprocesses. The fact is that free radicals of oxygen in the air react with the components of the oil and oxidize them. Changes in the chemical composition lead to changes in the physical properties of the lubricant. Valvoline Synpower SAE 5W-30 engine oil features an extended drain interval. It is able to withstand 13-15 thousand kilometers. Especially for this, manufacturers added aromatic amines and various phenol derivatives to the composition of the mixture. These substances trap atmospheric oxygen radicals, which increases the resistance of the entire mixture to oxidation.

Protecting the engine from corrosion

Engine elements made from non-ferrous alloys are exposed to corrosive processes. To protect them from rust, manufacturers have increased the proportion of anti-corrosion additives. Compounds of chlorine and sulfur create a thin, inseparable film on the metal surface, which prevents the further spread of rust. It is not destroyed by the action of any organic acids and by friction of parts.

Urban use

Constant starts and stops are accompanied by sudden changes in engine speed. This provokes the formation of foam. The process is also accelerated due to the introduction of detergent additives into the composition of the oil. These compounds simply reduce the surface tension of the mixture. As a result, the distribution of oil over the parts of the power plant changes, which can provoke premature engine wear. To prevent risksfoaming in this composition increased the proportion of silicon compounds. With their help, it was possible to destroy the air bubbles that form when the engine speed increases.

Fuel savings and longer engine life

Valvoline Synpower 5W-30 has been formulated with a large number of friction modifiers to increase power plant efficiency, reduce fuel consumption and extend engine life. In this case, metal acetates and borates, fatty acid esters are used. Substances create an inseparable film and reduce the friction of metal parts against each other. As a result, the resource of the power plant also increases, the period of its overhaul is postponed.

Driver Reviews

Valvoline Synpower SAE 5W-30 engine oil has won a lot of accolades. First of all, drivers note the reliability of this composition and the stability of quality. The advantage of lubrication is that it is not yet very popular. Faking this mixture simply does not make sense. In reviews of Valvoline Synpower 5W-30, owners also note a significant reduction in fuel consumption. Fuel consumption can be reduced by about 8%. Given the constant rise in prices for gasoline and diesel fuel, this figure looks quite significant. A positive opinion of motorists about the composition was also formed due to the extended drain interval.
