How to choose the oil of the car, I personally like to drive intensely, the car is a Cadillac XT5 20

As we all know, motor oil is like human blood. With it, the engine can work properly. Modern automotive lubricants have the following basic functions:

lubrication of moving parts such as engine pistons, camshafts, bearings, etc.; Cooling, taking away the high temperature generated by the combustion of the engine piston; Cleans and dissolves the sludge produced by combustion in the engine. However, a good oil can resist the excessive pressure on the internal parts of the engine during operation, reduce the friction of metal parts, and ensure that the engine can perform to its full potential. Therefore, a good engine oil can bring more power and driving experience, such as the Castrol EDGE, which I once changed, and it really performed well after changing it, and the overall feeling was much smoother.

And regarding the question of the oil change interval, according to the official manual, the oil must be changed every 10,000 km. Mineral oil models, on the other hand, may be shortened to 5,000 kilometers and need to be replaced. So I can't stress it again:

Be sure to read your maintenance manual carefully and decide how many kilometers to replace according to the content of the maintenance manual, so that the engine can work in a more perfect state to stimulate its performance. Then there's the age-old question of oil selection. First of all, the brand, which varies from person to person, as long as it is a large manufacturer, the quality of the engine oil is generally at the same level.

The second is the labeling. Today's motor oils are usually marked in the format x-y. x represents the cold viscosity index, and y represents the high temperature viscosity index.

In human terms, the smaller the x, the better the fluidity at low temperature, and the greater y, the greater the high temperature viscosity. I recommend asking what oil specifications SSSS uses when the first warranty, and use this as the lower limit to choose the right oil viscosity for your car, and for most OEMs, there will be special certification methods for engine oil, such as Volkswagen, Fiat, PSA and Ford, BMW, etc.

So the next question is how to buy engine oil. After all, the 4S store **280 a liter, although it can be guaranteed to be**, but the price is really a bit big. Nowadays, fake engine oil is rampant, and it is possible to buy a fake if you are not careful.

Laboratory results have shown that fake oil performs far worse than even the cheapest cheap** oil. JD.com's self-management seems to be a good place to go. Of course, Tmall*** is also a good choice.

According to reliable reports, Tmall***'s engine oil is a direct store, which will be more reliable. Once you've bought your oil, the rest is relatively straightforward. You can choose to change the oil filter yourself (the column has written about it), or you can choose to go to any repair shop and spend money to find someone to help you change it.

The specific operation is actually three, open the refrigerator, put the elephant in, and close the refrigerator. In other words, drain the oil, change the filter, and change to a new oil.

Hello, generally high-end cars use fully synthetic engine oil to lubricate the engine better, the oil change cycle is 8000 kilometers to change once, semi-synthetic oil is not suitable for this engine.

According to the tips of the Shenwei manufacturer, the Cadillac XT5 uses 5W30 engine oil. When buying motor oil, you can use any brand of motor oil as long as the oil label is correct and the oil is **. The owner can also check Zheng Xiao's change to see the vehicle instruction manual (user manual), which will also have a detailed introduction, and you can also use the engine oil specified in the manual.

The most important thing in using oil is not to use fake and shoddy oil. If you use counterfeit and shoddy engine oil, not only will it not protect the car engine, but it will also damage the engine.

Strictly speaking, there is no standard answer to what grade of oil a car uses, and it should be flexibly analyzed according to the actual situation.

For example, in severe cold areas such as the Northeast, you need to use engine oil that starts at 0w. If you are in a warmer area such as the south, you can use 20w engine oil.

As of November 30, 2019, the Cadillac XT5 is the most advanced 2020 model, with an official guide price of 10,000 yuan. There are 6 models on sale, all of which meet the national 6B emission standards.

It is powered by a four-cylinder turbocharged inline engine mated to a 9-speed automatic manual transmission, with a maximum output of 177 kW and a maximum torque of 350 Nm.

The oil model of Cadillac XT5 is 5W40, and when changing the oil, add about 4L, mainly to see the oil dipstick. Due to the high working power of the engine, its high working compression ratio makes the engine cylinder have a higher temperature, and the use of high-viscosity engine oil can protect the parts in the engine and play the role of cooling and lubrication.

In addition to the original engine oil, Cadillac models can also use other brands of lubricating oil, and if you care about the long-term effect of the oil, you can use Mobil oil; Pay attention to the cleanliness of the engine oil, you can use Shell oil; If you need a lubricant with strong film toughness, you can choose Castrol. For turbocharged engines, for example, carbon deposits are easy to occur at high speeds, so choose Shell fully synthetic motor oils with strong cleaning properties.

The oil used in self-priming engines is of average quality and can be used with mineral oil and semi-synthetic oil. All synthetic motor oils can be used if the consumer economy allows. Compared to self-priming engines, turbocharged engines are more accurate, work in harsher environments, use oils that require better performance, require lubricants that flow better, and are best suited with fully synthetic oils.

Engine oil, that is, engine lubricant, English name: engineoil. The density of about 10 (kg m) can lubricate and reduce wear, auxiliary cooling, sealing leak-proof, anti-rust and anti-corrosion, shock absorption and cushioning of the engine, known as the "blood" of the car.

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.

It is the heart of the car. There are many metal surfaces in the engine that rub against each other. These parts move fast, the environment is poor, the operating temperature can reach 400°C to 600°C, in such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and prolong the service life.

Motor oils on the market can simply be divided into mineral oils and synthetic oils because of the different base oils (vegetable oils are ignored due to their scarcity of production).

The Cadillac XT5 recommends the use of all synthetic motor oils.

In terms of power, the Cadillac XT5 is equipped with a turbocharged engine, and it is recommended to use synthetic engine oil with better performance.

There are three types of engine oil used in automobiles, namely mineral engine oil, semi-synthetic engine oil, and fully integrated oil engine oil. These three types of oils have different functions. Compared to the other two oils, fully synthetic oils lubricate better.

In addition, the service life of these three types of engine oil is also different, the use cycle of mineral oil is 5000km, the service life of semi-synthetic engine oil is 7500km, and the service life of synthetic engine oil is about 10000km.

Compared to naturally aspirated engines, turbocharged engines generate high heat during operation, with rapid relative slippage between the piston and cylinder, and between the spindle and the pads. If there is no oil to lubricate these parts, the parts inside the engine will wear out severely.

Synthetic engine oil has the characteristics of stability and durability, so it is recommended to use synthetic engine oil for turbocharged engines, which can provide better protection for the engine.

Millions of car purchase subsidies.
