What are the levels of oil, fuel, grease and coolant of the car, and how to use it better with the c

Engine oil: gasoline engine oil and diesel engine oil. Gasoline engine oil is divided into SG, SH, SI, and SJ levels, and the lower the letters, the better.

Diesel engine oil is divided into CD, CE, CF grades, and the lower the letter, the better. After that, it will be divided into 5w-30, 5w-40, 10w-40, 20w-50 levels, the front indicates low temperature, the back indicates viscosity, the lower the low temperature, and the higher the viscosity of the oil, the better, and the more expensive, for example, 10w-30 is cheaper than 10w-40.

Fuel oil is divided into gasoline, diesel and jet fuel.

Grease is divided into calcium-based and lithium-based, and semicolons, generally used No. 3 in summer and No. 2 in winter. Lithium-based is the most expensive and of the best quality.

Coolant is usually divided into -25, -35, -40, -50 according to the freezing point, and the lower the freezing point, the more expensive.

All these uses, the most critical point is what kind of car you are, in what region to use, the south does not consider the temperature, but to pay attention to other indicators, the north to consider the number of diesel, the number of lubricating oil and the freezing point of coolant, gasoline mainly depends on the car, generally 93 can be, high-end cars with 97 or higher.

A lot is complicated! Gasoline 93 or more! Oil:

According to the region, the season and the environment are different (if you can buy engine oil, people will explain it to you, and the general repair shop can) Grease: generally not too particular (dozens of dollars of Shell, Mobil, etc. can be used) Coolant: depending on what temperature you have, the lower the temperature, the more expensive!

I use minus 30 degrees in Chengdu is enough, you must use minus 50 degrees in Heilongjiang, the level is one, the key depends on the brand!! Big brands are trustworthy, but there are also many fakes!

These things are not clear to you in 1 moment, just take the very simple dyed oil as an example, the general van is actually added to the No. 90 oil, and the more high-end the car, the more oil will go up. That is to say, what car is with something, not that expensive things are necessarily good.

Cooling oil is better than coolant compared to coolant. Compared to coolant, cooling oil does not contain water and cannot be mixed with water, so the thermal balance ability of cooling oil is more sensitiveThermal conductionBetter ability, more ensure that the engine is in the best working temperature, do not corrode the heat dissipation system, and rubber pipe also has good compatibility, better lubrication performance, service life up to 30 years.

Coolant is also known as antifreeze coolant.

Ethylene glycol is commonly found on the market today.

The water-based type is mainly composed of water, ethylene glycol, antifreeze and other additives, which have antifreeze and cooling functions. Automobile cooling oil is actually anhydrous coolant, there is no water in the composition, pure additive synthesis, can also be called coolant.

Although antifreeze oil and antifreeze.

The essential characteristics are the same, the function and usage are the same, but there are obvious differences between the two, the most intuitive is that the coolant is water, the cooling oil is oil, and the coolant maintenance cost is low, and the cost of cooling oil is high; Coolant is somewhat corrosive to the cooling system, whereas cooling oil is almost non-corrosive.

The two are different things, and the place of application is different. Not comparable.

Summary. Hello, I'm glad to serve you Dear, if you want to better protect it, it can be replaced Because ordinary coolant is mainly the boiling point and freezing point attenuation is fast, it is easy to produce scale and cavitation, resulting in damage to the cooling system and poor engine work, and the better must be the oil cooling system, constant high boiling point and low freezing point, and there is no need to replace and supplement for life, which avoids the risk of damage to the parts caused by lack of water and the risk of opening the pot and pulling the cylinder, and will not cause the engine to age due to scale and cavitation, so as to avoid more and more fuel consumption and louder soundThe problem of worse power, but it is also relatively expensive, but it is cheaper to use for life, the fuel saving of the machine can reach 5-7%, the noise and vibration are significantly reduced, and the speed will be accelerated, because the excellent thermal conductivity can be very fast into the working temperature required by the machine, to avoid cold wear and carbon deposition, to avoid the powerlessness caused by the high water temperature of the engine caused by long-distance driving and high temperature weather, high fuel consumption and carbon deposits, in short, a money, a goods, a value!

Coolant is not exactly equal to cooling oil, coolant is equal to water plus antifreeze, in layman's terms, coolant refers to the liquid that can cool the engine, which can be water or antifreeze. Water is a very low-grade coolant and is limited by the season.

Under normal circumstances, the engine coolant (antifreeze) should be replaced every two or three years, but if the coolant is selected, the engine cooling system will also have no leakage, and the replacement time can be extended. If you don't have a special instrument, don't try your luck by feeling to avoid serious damage to the engine.

Cooling oil, the full name should be called engine cooling oil, is a non-combustible flame retardant liquid that does not contain toxic and harmful substances (ethylene glycol, propylene glycol), and has high safety. It has many advantages over conventional cooling media. It has sensitive thermal balance ability and ultra-fast thermal conductivity to ensure that the engine is in the best working environment; Constant temperature working temperature range, put an end to boiling and boiling, and cool the system under slight pressure; No antifreeze is added in low temperature environment; Corrosive damage such as cavitation, scale, and electrolysis is avoided.

Under normal circumstances, the service life of engine cooling oil is as long as 30 years, if the engine cooling oil is selected, the temperature around the cylinder wall of the car is in a controllable and relatively balanced state, which can recover the loss of car kinetic energy and fuel consumption, so the engine cooling oil can be fuel-efficient, improve engine performance and reduce exhaust emissions.

Automotive cooling oil, which is a coolant, has many advantages over traditional coolants (water). Sensitive thermal balance ability, super heat conduction ability, to ensure that the engine is in the best working temperature; Ultra-wide working temperature range, put an end to boiling and boiling, and cool the system under slight pressure; No antifreeze is added in low temperature environment; It avoids corrosion damage such as cavitation, scale, and electrolysis. It has good compatibility with rubber tubing.

The coolant is composed of ethylene glycol, anti-corrosion additives, anti-foam additives and water, among them, ethylene glycol is the core ingredient that expands the temperature range of the liquid, through the fusion with water, the high concentration of coolant can not boil and freeze within 197 to -60, the color of the coolant used in different brands of models is different, there are pink, and blue, etc., these are the different color effects created by the colorant, in order to be more eye-catching when the coolant leaks, it can be more eye-catching. The difference in color will also distinguish different products very prominently, so as to prevent the wrong owner from mistakenly adding products that are not suitable for their car.

The functions of car antifreeze are:

1. Prevent the coolant from freezing and cracking the radiator and freezing the engine cylinder block or cover when parking in the cold winter.

Its main indicator is the freezing point of the antifreeze. When selecting or formulating the anti-liquid, its freezing point should be 10 times lower than the lowest temperature in the region

left and right to ensure that the antifreeze does not freeze in exceptional cases. Another important function of antifreeze. Its main indicator is the boiling point. The boiling point is.

It refers to the condition that the cooling system of the automobile engine is balanced with the outside atmospheric pressure, and the coolant begins to heat up to the boiling control temperature and no longer rises.

high, keeping the engine working at normal temperatures. Antifreeze also provides protection against corrosion. Corrosion is caused by the metal being in the natural environment.

Learn reactions, electrochemical processes, and physics to be destroyed remotely. At present, there are six kinds of metals that are mainly anti-corrosion, namely: steel, cast iron, etc

Copper, solder, brass, cast aluminum. Most of the cooling systems of modern automobile engines are made of cast aluminum and aluminum alloy parts, so they are required to be anti-freeze.

The focus of liquid corrosion protection should also shift to the corrosion protection of aluminum, and non-metallic materials such as rubber and plastic in the cooling system should also be considered.

Dissolving, bulging, aging, etc. Corrosion inhibitors are substances that stop or slow down these processes. Waterproofing is another aspect of antifreeze.

Importantly, fouling is caused by the attachment of insoluble salts or oxide crystals on the surface of the radiator. After the scale is generated, it will not only affect the dispersion.

The normal heat dissipation of the heater is more likely to cause the blockage of the circulation pipe of the cooling system, and the water temperature is too high and seriously affects the positive of the engine.

Constant operation. The main substances that can produce limescale in the cooling system: calcium sulfate, calcium carbonate, magnesium carbonate, etc., as well as due to improper use.

Brown calcium phosphate produced, etc. Calcium and magnesium ions are mainly used in the water in the coolant, so the preparation of cooling antifreeze must be strictly controlled.

water quality. Second, the requirements for adding coolant.

According to the structural characteristics of the engine, the manufacturer has made strict requirements for the use of coolant for the hijacking machine, and the long-term antifreeze for general use.

There are clear requirements for rust liquid. Be sure to add antifreeze leakage due to water loss or other reasons caused by long-term use.

Distilled water, never add river water or tap water, due to the lack of experience in the performance of antifreeze, the water quality requirements for adding cooling water are not strict.

It will cause fouling in the waterway, affect the normal circulation of engine cooling water, and reduce the cooling intensity, so that the engine temperature is too high and reduced.

According to the introduction of some automobile cooling oil manufacturers on the Internet, such as Huibang cooling oil, it is said that automobile cooling oil is a new technology product of the replacement of coolant. All internal combustion engines in history were powered by water to dissipate heat, but later coolant and thermostats were added to the cooling system to facilitate freeze protection and faster start-up at low temperatures.

Later, in order to avoid the difficulty of mastering the proportion of water content when customers add coolant by themselves, the cooling manufacturer directly increases the proportion of antifreeze with water.

Water and aqueous coolant cannot meet the congenital defects of engine heat dissipation: 1. Water will freeze at 0 and boil at 100. Ice can inflate the engine's water tank and cylinder block, and boiling the pot can overheat the engine until it causes paralysis.

2. When the engine temperature reaches more than 80, water bubbles should begin to produce on the cylinder wall. Water bubbles form a bubble barrier layer on the cylinder surface, preventing heat from escaping from the engine. Water bubbles are endlessly formed and burst on the metal surface of the engine block, and the cylinder block is lost in a dripping effect This is cavitation.

3. The local temperature inside the engine is too high, and the pre-ignition and detonation tendency increases, which increases the vibration and noise, greatly reduces the performance and efficiency of the engine, and forms no water and fuel consumption.

4. Under the action of electrolyte, electrochemical corrosion occurs and rust and scale are produced, which aggravates the aging rate of the cooling system and reduces the heat dissipation performance.

5. When the engine temperature reaches more than 80, the water vapor, water bubbles and water body expand, which increases the internal pressure of the cooling system. In this way, it not only catalyzes the aging rate of the cooling system, but also makes it impossible to ensure the speed required for normal heat dissipation due to corrosion.

Therefore, the heat dissipation defects of aqueous coolant are summarized as follows: the heat dissipation performance is limited, and the overheating vertex cannot be suppressed; The engine gradually ages, so that the engine heat generation increases unabated; The cooling system gradually ages, so that the heat dissipation capacity is reduced but not increased.

The revolutionary innovation of automobile cooling oil improves and further solves the defects of the above coolant, which adopts the world-class engine thermal management technology to control the engine to work in about 90 temperature environment, and this temperature is recognized as the best working temperature environment of the engine, in this temperature range to work with the lowest fuel consumption, reduce emissions, and reduce engine wear and maintenance costs, improve the life of the engine.

Economically, the coolant needs to be replaced once every 1 or 2 years, and the car cooling oil (such as Huibang cooling oil) is installed once, and 500,000 kilometers are maintenance-free.
