What are the benefits of a fully synthetic motor oil, and what are the benefits of a fully synthetic

Hello! Regarding your inquiry, ordinary lubricating oil is processed and refined, the main component is a mixture of various n-alkanes, isoparaffins, and naphthenes, while fully synthetic engine oil is not produced by refining, but by chemical synthesis, and the synthetic lubricating oil used for lubrication mainly includes polyalpha olefin oil, various esters, etc. Fully synthetic motor oil has better oxidation stability, higher viscosity index, better low-temperature lubricity, and relatively stable high-temperature stability.

For cars, synthetic engine oil is more conducive to engine lubrication, you can use the same synthetic engine oil as the original factory marking, or higher is better. Replacing the fully synthetic lubricating oil can appropriately extend the maintenance interval of the vehicle, and it can be maintained once every 15,000 kilometers when the road conditions are good. However, if the vehicle is driving in very poor road conditions, even if you use fully synthetic engine oil, it is best to change the oil according to the 7500 km service interval.

However, the use of fully synthetic motor oil does not have a particularly noticeable change in the dynamics of the engine.

1. It does not contain sulfur, and the use of fully synthetic engine oil is longer lasting and environmentally friendly.

In the American Petroleum Institute's API definition, the sulfur content of Class I base oils, Class III base oils have < sulfur content, while Class IV PAO sulfur content is 0%.

2. Fully synthetic engine oil has fewer impurities and strong cleaning performance.

After changing the fully synthetic engine oil for the first time, you will find that the small sludge particles in the oil will increase very quickly after a while.

This is because the newly added fully synthetic engine oil will be cleaner and will break down the sludge that has accumulated in the engine oil pipe into small sludge particles.

The advantages of using fully synthetic engine oil are as follows: 1. Synthetic oil is generally a pure compound with a narrow boiling point range, and its evaporation loss is much lower than that of mineral oil, which can reduce fuel consumption, reduce exhaust emissions and extend the service life of catalytic converters. 2. The thermal oxidation stability of synthetic oil is much better than that of mineral oil oil, that is, the tendency of acid and sludge due to oxidation is small, and it can provide proper lubrication and effective protection for the engine under various harsh operating conditions, so it has a longer service life.

3. The viscosity index of synthetic engine oil is higher than that of mineral oil, and the viscosity changes with temperature small. When the high temperature viscosity is the same, most synthetic oils have a lower pour point (or freezing point) than mineral oil, and the low temperature viscosity is small.

The advantages of fully synthetic engine oil: (1) excellent viscosity and low temperature fluidity (2) strong high temperature oxidation resistance (3) low evaporation loss. Synthetic motor oil also has the characteristics of excellent chemical stability, good radiation resistance, high oil film strength and less foam.

Engine oil blended with Class 4 and 5 base oils without blending with mineral oil can be called fully synthetic engine oil.

Synthetic motor oil is a motor oil synthesized and manufactured by humans using the chemical method of chemical chemistry, and according to the purpose of use, synthetic motor oil can change various compositions. Work on the development of synthetic motor oil began in the 30s. At that time, due to the harsh conditions for the use of aircraft engine oil, which required a higher performance engine oil, some chemical factories began to develop and produce synthetic engine oil.

With the rapid progress of modern chemical technology, after the 90s, the performance of synthetic motor oil has been greatly improved.

Sulfur-free, fully synthetic motor oil for longer life and environmentally friendly.

Fully synthetic motor oil has fewer impurities and strong cleaning performance.

The following are the benefits of fully synthetic motor oil:,1. Fully synthetic oil has a wider temperature range than semi-synthetic oil and mineral engine oil. 2. Synthetic oil is not easy to deteriorate, has low evaporation loss, and has a longer service life than ordinary oil.

3. It has excellent chemical stability, good radiation resistance, high oil film strength and less foam, good lubricity and low wear. 4. The thermal attenuation of fully synthetic oil is reduced, which saves fuel and can better protect the engine. Here's what the oil does:

1. Lubrication and friction reduction: between the piston and the cylinder, between the spindle and the bearing, there is a rapid relative sliding, to prevent the parts from wearing too quickly, it is necessary to establish an oil film between the two sliding surfaces, and separate the surface of the relatively sliding parts, so as to reduce wear. , 2. Cooling and cooling:

The oil brings heat back to the oil tank and dissipates it into the air, helping the tank cool the engine. 3. Cleaning and cleaning: good engine oil can bring carbide, sludge and wear metal particles on the engine parts back to the oil tank through circulation, and wash the dirt generated on the working surface of the parts through the flow of lubricating oil.

Generally, we change the engine oil according to the use of the engine oil to decide whether it needs to be replaced, drop the oil on a piece of white paper, and then identify the oil use according to the oil color replacement judgment chart. With constant use, the oil will slowly deteriorate and be mixed with impurities. Lost.

1.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

2.Semi-synthetic engine oil: The replacement cycle of semi-Huijin synthetic engine oil is generally about 8000-10000 kilometers, which is moderate in terms of performance.

3.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil due to saving, long life, high efficiency, the front ant base has a better protective effect on the engine. Due to the characteristics of multi-grade oil, there may be premature blackening and less oil pressure than ordinary oil during use.

<> "Fully synthetic engine oil strictly refers to high-quality engine oil products that are 100% made of PAO or synthetic esters, and the word "synthetic" is generally marked on the oil drum. So what does a fully synthetic motor oil do?

Lubrication reduces wear, there is a rapid relative sliding between the piston and the cylinder, between the main shaft and the bearing, and the oil forms an oil film of sufficient thickness between the two sliding surfaces to separate the surface of the relatively sliding parts and reduce wear;

Cooling and cooling, the engine oil can bring the heat and reputation back to the oil tank and then dissipate it into the air to help the water tank cool the engine;

Cleaning and cleaning, the oil can circulate carbide, oil sludge and wear metal particles on the engine parts back to the oil tank, and flush the dirt generated on the working surface of the parts through the flow of lubricating oil;

Shock absorption buffer, when the pressure of the engine cylinder port rises sharply, suddenly aggravates the load on the piston, piston chips, connecting rod and crankshaft bearing, and the negative local load is transmitted through the bearing to buffer the shock load.
