Which engine oil is the best way to buy on the market?

Since my car was out of warranty, I have been using German GT Magic Red engine oil, which is very high-end, and it is a fully synthetic engine oil, with slow attenuation and long oil change cycles.

First up is Shell. The full name is Royal Dutch Shell Group, which is the world's oil company. It is a major international oil, gas and petrochemical producer and a global retailer of automotive fuels and lubricants.

Its outstanding feature is its high cleanability. The sludge and carbon deposits that are easily generated by the engine can be filtered out, so that the engine can be kept in good working condition for a long time. And the power response is also very good, which can be reflected in the engine with high assembly accuracy.

When you step on the throttle, there is an immediate power response.

And then there's Mobil. Mobil is characterized by its low susceptibility to cracking, so the oil change cycle is relatively long, and its products have good movement and high temperature resistance. These characteristics are due to the development of polyolefin base oils by Mobil.

The molecules of this base oil are arranged in a neat manner, which can resist external interference, so it has good resistance to oxidation and viscosity changes.

Then there's the well-known Castrol. The selling point of Castrol products is the good flow performance at low temperatures and the good protection of the engine from cold starts. In areas with low temperatures, vehicles with difficult cold starts, or older vehicles, Castrol is also a good choice.

But when it comes to choosing different brands of oil, if you're in a place where road conditions are always good, you can choose Shell, but you need to change the oil frequently. If it's a cold place, choose Castrol, and if you need good power and heat protection, choose Mobil.

Car maintenance is a problem that all car owners will encounter, and oil change is a must-have item. When changing the engine oil, many car owners will face the choice of engine oil, including brand, specifications, etc., at this time, car owners who are not familiar with engine oil often fall into "difficult choice syndrome".

We all know the importance of the engine, and there are many parts of the engine, in order to ensure its normal operation, it must be indispensable engine oil. It can be said that the performance of the car engine can be fully exerted depends on the oil used.

Engine oil may not be paid attention to by everyone, but when it comes to maintenance, it is found that there are many brands of engine oil, and there are certain differences between different brands, and some of the differences are very big, if you choose the wrong one, not only waste money, but also hurt the car.

The selection of engine oil is difficult to say, and simple to say.

At present, most of the private cars in the market use fully synthetic and semi-synthetic motor oil, and today Topland maintenance experts will tell you the difference between the two.

Fully synthetic motor oils have better performance at high and low temperatures, as well as longer oil change intervals, making them more suitable for harsher vehicle conditions.

Semi-synthetic oil contains more mineral oil, has a higher flow point, is not suitable for use in low-temperature areas, and has a shorter oil change interval than fully synthetic oil, but it is lower.

So what should you choose between the two?

AutomotiveIf you fall into any of the following situations, Topplan's maintenance experts recommend that you use a fully synthetic oil:

1. The models are turbocharged models, in-cylinder direct injection models, large-displacement models and SUVs;

2. Like to drive fast, like to stop and go in the city, and start the car frequently;

3. The vehicle is a luxury brand;

4. Rich and capricious, willing to spend money to maintain the car;

If you are one of the following, it is recommended that you use semi-synthetic:

1. The car is a non-turbo model;

2. Economic cars, models within 200,000;

3. The replacement mileage is within 7000 kilometers or six months;

Generally speaking, there is no absolute quality of engine oil, only the oil that is suitable for your car can really be regarded as "good engine oil".

A good engine uses semi-synthetic engine oil, which can not give the best performance of the engine and damage the engine.

The general engine is fully synthetic, and the maximum effect of the engine oil cannot be exerted, which seems to be a waste of money.

1.Engine oil, that is, engine lubricating oil, can lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the "blood" of automobiles.

2.Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of lubricating oil.

3.The 5W W-30 and so on in the engine oil indicate the viscosity grade of the engine oil, which is the SAE grade. "W" means winter.

The smaller the number in front of w, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature. The number after w does refer to the viscosity of the oil at 100 degrees Celsius, and the higher the number, the more viscous the oil. The following figures mainly refer to the index of the high temperature resistance of the oil, and the better the protection performance at high temperatures.

4.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.

5.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

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

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to saving, long life and high efficiency.

Hello! Engine oil is lubricating oil, which is the lubricating oil that is filled by the engine and used to lubricate engine parts. The high-end is fully synthetic, the mid-range is semi-synthetic, and the low-end is mineral oil.

Engine oil is the lubricant used in motor vehicle engines, which needs to be checked and replaced regularly so that the engine can be kept in good condition and can play better performance and power.

The so-called engine oil is the lubricant of the mechanical system, which is called lubricating oil because of its relatively large oiliness.

If the rotating parts of the mechanical part are directly rubbed against each other, not only the heat is fast, but also the damage is fast, so there must be lubricant to ensure that the friction between the parts becomes controllable and reliable, to ensure the operation efficiency of the machine, reduce the heating temperature, prolong the service life and work reliability.

The lubricating oil applicable to your car is contained in your car manual or called the manual, you had better take the time to carefully read the documents with the car, and use the correct lubricating oil according to the description of the manual.

As long as it is regular in the market, it is okay, as long as it is not produced by a small workshop, it can be trusted.

Under the premise of quality, of course, the lower the quality, the more cost-effective.

1. Cooling and cooling: The oil can bring the heat back to the oil tank and then dissipate it into the air to help the water tank cool the engine.

2. Sealing and leakage-proof: The engine oil can form a sealing ring between the piston ring and the piston to reduce gas leakage and prevent external pollutants from entering.

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.

4. Shock absorption and buffering: When the pressure of the engine cylinder port rises sharply, the load on the piston, piston chips, connecting rod and crankshaft bearing is suddenly aggravated, and the load is transmitted and lubricated by the bearing, so that the impact load bears plays a buffering role.

5. Lubrication and wear 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. An oil film of sufficient thickness separates the surface of the relatively sliding part to reduce wear.

6. Anti-rust and anti-corrosion: lubricating oil can be absorbed on the surface of parts to prevent contact between water, air, acidic substances and harmful gases and parts.

Hello Engine oil is a necessity for a car, engine oil can reduce engine wear, and high-quality oil will have better results.

If you think of the engine as a heart, then the oil is the engine's"Blood"It is a vital part of engine maintenance. Shell, Mobil, Castrol oils
