What are the benefits of synthetic oil

The advantages of a synthetic oil,

The synthetic oil is prepared by chemical synthesis of high molecular compounds, lubricating oilafter deployment or further processed. It includes the synthesis of esters, poly alpha olefins,polyether, silicone oil, its components with different petroleum hydrocarbons. Semi synthetic oilrefers to the lubricating oil synthetic oil and mineral oil made by blending. Because of the expensiveraw materials of synthetic oil, synthesis of complex, high investment, so synthetic oil and semi synthetic oil prices are generally higher than mineral oil.

Compared with synthetic oil and mineral oil has the following excellent characteristics.

(1) the viscosity temperature and excellent low-temperature fluidity

Synthetic oil than mineral oil with high viscosity index, smooth wrench lung colonization plating helpmonk viscosity with temperature change small explosion kyrgyzstan. At the same time high temperature viscosity, most synthetic oil than mineral oil pour point (or point) low temperature, low viscosity. Oil film the same requirements, synthetic oil can lower viscosity can be formed, to achievethe purpose of engine protection. Therefore, can reduce the energy consumption of automobile inlow temperature startup, prolongs the service life of the accumulator; at the same time, because ofthe oil flow to the surface of the friction time need to short, can reduce the engine componentsappear in the start of the dry wear phenomenon, prolonging the service life of the engine.

(2) high temperature oxidation resistance

The thermal oxidation stability of synthetic oil than mineral oil type oil well, which is due to oxidation and acid production, the trend of small clay, in a variety of harsh operating conditions, to provide adequate lubrication and effective protection to the engine, so it has a longer service life, ensure themachine oil in long-term performance stability during the period of.

In the same working environment, because of the use of synthetic oil period is much longer than the mineral oil, so although the cost is higher, butrelatively changing times, not much higher than mineral oil.

(3) low evaporation loss

Synthetic oil is generally a pure compound, boiling point range is narrow, the evaporation loss thanmineral oil is low, can reduce fuel consumption, reduce emissions and prolong the service life of the catalytic converter.

In addition, compared with the traditional mineral oil, synthetic oil also has excellent chemical stability, radiation resistance and high film strength and less foam characteristics. Therefore, the general high-grade car choose synthetic oil.

Two, how to distinguish between full synthetic oil, semi synthetic oil and mineral oil

The full synthetic oil, semi synthetic oil with mineral oil prices high, some unscrupulous traders will be labeled as mineral oil synthetic oil sale, by the user, in order to reap high profits. How todistinguish the oil, avoid to be deceived? The best way is to use scientific instruments, through theinfrared spectrum analysis instrument of oil structure, to distinguish what type of lubricating oil. For ordinary users lack of analysis method, also can use the following method to identify:

If is the ester synthetic oil, preferable oil sample and ordinary mineral oil mixed with mineral oil,because of its immiscibility, showing a turbid state after mixing, after standing for a long time will nototherwise stratification, ester oil.

If is polyalphaolefin, it can be miscible with mineral oil, but its viscosity index is very high, generally more than 140, and the wax, the pour point 2, usually at -40 DEG C, the temperature dropped to -30DEG C when determination of pour point oil can keep clear and transparent. If it is a paraffinic mineral oil, viscosity index is relatively high, but the high pour point, the temperature dropped to -30DEG C is opaque when oil pour point determination; if it is naphthenic mineral oil, viscosity index is low, generally less than 80, the other state.

The semi synthetic oil is generally made of poly alpha olefins and paraffinic mineral oil according to a certain proportion, in addition to using the instrument analysis, there is no better way.

In three, matters needing attention when the synthetic oil

Synthetic oil generally refers to the poly alpha olefin (PAO) as the base oil, it is a kind of pure substance, and can be miscible with mineral oil. Good adaptability of synthetic oil for long-spanenvironmental temperature and characteristics greatly extend the oil change period, more and more users favor. However, due to the PAO base oil additives on the poor solubility, so often join an ester(usually diester and / or polyol ester), together as base oil. The additive is soluble in oil and ester,ester oil and miscible with PAO, so as to solve the problem of dissolved additives in synthetic base oil. Similarly, PAO can make the sealing rubber shrink, and ester oil will make the rubber expansion.Therefore, when the two kinds of base oil coexist, the rubber impact will offset.

When will a typical mineral oil engine oil for synthetic oil will produce some typical problems. As one of the components of base oil synthetic oil with pure natural ester role, it will use the mineral oilmembrane due to the thermal oxidative decomposition is formed in the inside the engine clean,floating on the surface of lubricating oil. The surface of the material will clog the filter, and plug the circuit leads to insufficient fuel. Therefore, in a period of time using mineral oil and synthetic oil forthe engine, we must pay attention to: first cleaning lubrication system must be in the oil before, andto check carefully before starting the engine.
