The main element of protecting the car engine from premature wear is engine oil. Now on the market there are a lot of products of this class, so motorists often have real problems with selection. In the “G-Energy” line of oils, you can find lubricants designed for both diesel and gasoline engines.
A little bit about the brand
The trademark itself is owned by the Russian state holding Gazprom. Oils are produced in the city of Bari in Italy. The enterprises have a multi-level system of product quality control, which is confirmed by various international certificates.
Oil line
G-Energy engine oils are only synthetic or semi-synthetic. The brand, in principle, does not produce mineral compounds. Hydrocracking products of hydrocarbons are used as the basis for synthetic motor oils. The final properties of the oils are modified using a wide variety of additives.
Semi-synthetic variations are made with a mineral base. Moreover, such formulations are slightly lower than fully synthetic. These types of oils are often used for used engines, the mileage of which reaches 30-50% of the total resource.
Characteristics
Reviews of G-Energy oils vary widely. The fact is that the final characteristics of the product completely depend on the type of additives used.
Antioxidant additives inhibit the oxidation of substances in the oil with atmospheric oxygen. These components allow you to keep the basic physical and chemical properties of the oils stable throughout the entire period of operation. In this case, oxidation products can be deposited in the piston rings, significantly reducing the motor power. Chemists of the company use a variety of aromatic amines and phenol derivatives as antioxidant additives.
Corrosion inhibitors are used to inhibit the oxidation of metal surfaces made from alloys of various non-ferrous metals, for example, crankshaft bearing shells. In this case, it is customary to use phosphorus-containing compounds, various derivatives of benzotriazole. The principle of operation is to create a durable film on a metal surface, which prevents further contact of the alloy with other chemical compounds.
Viscous additives are necessary to maintain the oil density at a stable level at different temperatures. Various polymeric compounds with a long carbon chain are used here. As the temperature rises, the macromolecules "unwind", which leads to a slight increase in density. In frost, the opposite effect is observed. Polymer compounds form a denser structure, which reduces the viscosity of the whole composition. As viscous additives, copolymers of dienes with styrene, polymethacrylates are used.
Friction modifiers are primarily intended to reduce fuel consumption and increase engine efficiency. In the "G-Energy" oil, in this case, various compounds based on molybdenum, borates of other metals are used.
To maintain the cleanliness of the pistons, it is customary to use a variety of detergents. They are often used in G-Energy oils designed specifically for older engines. The quality of motor fuel at many gas stations leaves much to be desired. Gasoline and diesel fuel contain a large number of sulfur compounds. Upon combustion, they form a solid precipitate that can be deposited on the metal parts of the engine. As a result, the motor begins to knock, power decreases, fuel consumption increases. In reviews of G-Energy oils, drivers note that after applying such formulations, the engine starts to run much quieter.
Dispersing additives are used to prevent further coagulation of solid particles. In this case, polyesters, high molecular weight Mannich bases, polyamines are used. The principle of operation is simple. The polar part of the molecule is fixed on the surface of the solid particles, and the carbon radical prevents it from sticking to other compounds.
Antiwear additives have high cohesive properties. On the surface of metal parts they form a thin and durable film, which prevents the occurrence of scoring, scratching. In this case, manufacturers most often use phosphorus-based compounds.
The use of detergents increases the likelihood of foam formation. As a result, the quality and stability of oil distribution over engine parts is reduced. This can lead to increased wear on the power plant. Therefore, the company's chemists add anti-foam additives to the oils. In this case, it is customary to use different silicone-based compounds.
Use season
Previously, almost all oils had a pronounced seasonality. Separately, compositions intended for summer or winter were used. Now the most popular are universal types of oils. Of course, when operating a car in the Far North, it is recommended to use only summer or winter lubricants.
G-Energy engine oil is intended for use all year round. Depending on the temperature of the region in which the vehicle is operated, the type of lubricant should also be selected. For example, in reviews of G-Energy 5W40 oil, drivers recommend using this compound at a temperature not lower than -30 ° C. In more severe frosts, the viscosity of the grease will not allow a safe engine start. By the way, the presented classification by viscosity parameters was proposed by the American Association of Automotive Engineers (SAE). Now it is she who is the most universal for all lubricants of this class.
engine's type
The manufacturer offers oils for gasoline and diesel engine types. The lineup also includes more universal compositions suitable for both types of motors. Such variations of oils are not in high demand among motorists. Just the principle of the engines and the type of fuel used for them is quite different. As a result, it is recommended to use only the oil that was originally developed for a particular power plant.
Exploitation
According to manufacturers, the oil change interval is 20 thousand km. In reviews of G-Energy 10B40 oil, drivers confirm the figures presented. Even after such an impressive run, the composition does not lose its operational properties. Motorists recommend periodic visual inspection of the quality of the lubricant. In the event of severe darkening of the oil or the appearance of extraneous impregnations, the replacement should be carried out immediately.
Cost
The prices of G-Energy oil are low (from 190 to 455 rubles - 1 liter, from 700 to 1560 rubles - 4 liters, from 880 to 2000 rubles - 5 liters). Semi-synthetic variations of the compositions are lower than fully synthetic analogues. In any case, the lubricants of this brand are worth less than analogues from other manufacturers.
Security
G-Energy oil is best purchased at gas stations of Gazprom and Gazpromneft. This will eliminate the risk of buying a fake composition.
