How do you know what kind of oil you add to your car, and what kind of oil does your car add to your

In the past, there was no problem with adding 97 gasoline and suddenly adding 93 gasoline, and it was better to fill that grade of gasoline in general. Check the car with petrol designation.

Method: 1. Check the car instruction manual, which records the number of gasoline that the car should be filled.

2. The fuel label will be indicated on the fuel tank cap, and it will be recommended how many gasoline you should fill, preferably with a few gasoline.

Extended Materials. At present, there are 3 gasoline grades in China (IV), namely No. 90, No. 93 and No. 97. Countries (v) are No. 89, No. 92, and No. 95 respectively (No. 98 in the Appendix). Gasoline grades are based on octane numbers.

Divisional. High compression ratio.

If the engine uses low-grade gasoline, the cylinder temperature will rise sharply, the gasoline will not be burned completely, and the machine will vibrate strongly, so that the output power will be achieved.

Decline, damage to parts, fuel consumption and driving weakness. If the engine with a low compression ratio uses high-grade oil, there will be a "stagnant burn" phenomenon, that is, when the compression ratio is the highest, it is not yet the spontaneous ignition point, and there will be incomplete combustion, which is not good for the engine.

I drove out today and found that the fuel gauge was on a red light.

At this time, I saw a sign on the side of the road that said "Car Refueling 92 Price Reduction", isn't this just the right solution to my problem, go and see! After learning about my refueling model, the boss took out an iron bucket from the house, connected a pipe and added it to my car. After a while, it was full, and the boss only asked me 150, which was cheaper than the car - car moving fuel card.

I drove away, but also immersed in the joy of a big bargain, but not far away my car as if sick there was shaking, abnormal noise, or poor power output, stepping on the accelerator did not have much power, should be "full of energy" of the car, instantly dull, so I suspect that I added inferior oil. In the end, I had to contact the 4S shop for cleaning and repair.

Highlight the point. What is Inferior Oil?

There are generally three types of low-quality gasoline: water-blended gasoline, blended oil, and dirty oil.

Water-blended gasoline refers to a gasoline product that is mixed with physical or chemical synthetic agents and mixed with water in gasoline. Long-term use can cause damage to the oil pump, injectors, filters and even the engine.

The best blended oil on the market is mainly synthesized from naphtha by adding various chemical raw materials. Naphtha, also known as "crude gasoline", is a light oil used for chemical raw materials processed and produced from ** or other raw materials, mainly used as reforming and chemical raw materials. After adding "blended oil", the car will be weak, the oil is not durable, the uphill can not go, and the car pops.

Dirty oil refers to the high amount of glue in gasoline, which is called "dirty oil" in the industry. After adding dirty oil, the car will be very prone to fuel filter blockage, fuel injector blockage and poor fuel injection atomization, etc., and it is easy to form carbon deposits in the valve and combustion chamber for a long time, resulting in abnormal engine operation.

Highlight the point. How to distinguish a bad quality oil?

See. Standard gasoline is more translucent in color, colorless or yellowish. If the oil is cloudy, whitish or dark, there may be a problem. For example, if there is too much gum in gasoline, it will appear orange or dark red, while gasoline with too many impurities will look cloudy.

Sniff. The taste of inferior gasoline generally presents two extremes, one is mixed with gasoline, and the gasoline smell is too light; Second, gasoline has a pungent odor, foul smell and excessive gasoline smell, and such oil contains excessive sulfur or is mixed with chemical raw materials such as methanol and naphtha.

92 and 95 are just the labels of gasoline, which represent anti-knock performance, and the chemical meaning is the octane number of gasoline, which has nothing to do with cleanliness. Otherwise, it is easy to cause "knocking", which is extremely harmful to the engine. I don't know the difference between high and low grade oil, usually mixed with the actual car owner only needs to follow the vehicle manual to recommend the number to refuel, do not change the label at will.

How much oil to add? If you run to the city, add 1 3 or 2 3 to the fuel tank. Because there are many traffic lights in urban areas, there is no need to fill up the fuel tank with frequent stop-and-go.

Filling up the tank will increase the load on the engine, resulting in higher fuel consumption. Moreover, there are many gas stations in the urban area, so there is no need to worry about not being able to find a gas station to refuel. But you can't wait until the fuel is completely depleted, and when the fuel gauge needle is close to or just pointing to the red line, it's time to think about refueling.

If you want to refuel, it is recommended to refuel in "liters", preferably in units of 10 liters, such as 10 liters, 20 liters, 30 liters, and so on. When refueling, don't directly say "how much to add", because after rounding, it will either be less or less, and it will definitely not be more, and you will lose your money invisibly. After refueling, the fuel tank cap should be locked tightly to reduce oil evaporation losses and keep the oil clean.

Look at the user manual, which has a detailed description, it is better to add a high grade 97 gasoline.

When buying a car, the 4S store will tell you what size of oil to add, and if you forget it, you can call ** to ask the store.

Look carefully at the owner's manual, the owner's manual will write what kind of fuel to add to this car.

Just take a look at the car's manual.

The question is simple, see what the manual says.

There is usually a sticker on the inside of the fuel tank cap that says what to add.

When the compression ratio arrives, choose 92 gasoline, and when the compression ratio arrives, choose 95 gasoline. If the compression ratio is above, choose No. 98 gasoline. The specific choice of gasoline is determined by the compression ratio of the engine.

The biggest difference between 92 and 95 gasoline is the difference in the ratio of n-heptane and isooctane. In terms of composition, 92 gasoline has 92% isooctane, while 95 gasoline is different, with 95% isooctane. For gasoline, the higher the proportion of isooctane, the better the corresponding anti-knock performance.

Gasoline options. If the engine with a high compression ratio uses low-grade gasoline, the cylinder temperature will rise sharply, the gasoline will not burn completely, and the machine will vibrate strongly, so that the output power will be reduced and the parts will be damaged. If the engine with a low compression ratio uses high-grade oil, there will be a phenomenon of "flame retardation", that is, it will not reach the spontaneous ignition point when it is pressed to the head, and there will be incomplete combustion, which is not good for the engine.

When the car leaves the factory, it is specified what type of gasoline to use. Usually the car's fuel tank cap will be marked with the recommended gasoline number, according to this standard to choose the gasoline number.

93 is used for general, 97 is used for advanced ones, and 97 is generally used for supercharged engines.

It's enough, but adding 93 to some good cars will increase the maintenance fee, and if all cars add 97, it's okay, but the cost will be high.

No. 93 is the isooctane content in gasoline is 93%, No. 93 is the isooctane content in gasoline is 93%, No. 97 is 97% of the isooctane content in gasoline, and the rest of the percent is the content of n-heptane.

However, many people have a misunderstanding that the higher the grade of gasoline, the better, but in fact, it is not, and the long-term inappropriate high grade gasoline will only damage the engine.

3. At present, there are a variety of different grades of gasoline on the market, and whether the use of gasoline meets the standards is closely related to the maintenance of the car. Therefore, experts advise car owners: do not pursue high-grade gasoline too much.

Whether the use of gasoline meets the standards is closely related to the maintenance of the car. The long-term use of low-grade gasoline in high-end cars will cause problems such as damage to the internal parts of the engine and seriously shorten the life of the engine.

1.The gasoline engine is ignited and has a low compression ratio; The diesel engine is compression-ignition with a high compression ratio. The gasoline engine compression ratio for the sedan is 8 11, and the diesel engine compression ratio is 18 23.

2.We usually say No. 90, No. 93, No. 97 gasoline, this value represents the label of gasoline, that is, the ratio of the actual gasoline anti-knock to the standard gasoline anti-knock resistance. The higher the grade, the stronger the anti-explosion performance.

Standard gasoline is composed of isooctane and n-heptane. Isooctane has good knock resistance, and its octane number is set at 100; N-heptane has poor knock resistance, and is prone to detonation on gasoline engines, and its octane number is set at 0. If the gasoline is marked 90, it means that the gasoline of this grade has the same anti-knock properties as standard gasoline containing 90% isooctane and 10% n-heptane.

3.The only criterion for choosing a gasoline grade is the compression ratio of the car's engine. Generally speaking, the higher the compression ratio, the smaller the volume of the flammable mixture to be compressed, the more powerful it is, and the lower the fuel consumption.

However, the compression ratio has to be matched by another index, which is the anti-knock index of gasoline, also known as octane number, that is, gasoline labeling. The higher the compression ratio, the higher the anti-knock index of gasoline, that is, the higher the grade of gasoline.

4.China's automobile engine is mainly imported or produced with reference to foreign standards, at present, the foreign oil market only has these three grades of gasoline, and the compression ratio of the engine is also designed with reference to these three grades, so there are not many engines that match 90 gasoline. However, now the phenomenon of lowering the standard with oil is extremely common, according to calculations and observations, most of the compression ratios of small cars are above, and some imported cars are even above the compression ratio, which should use more than 95 gasoline.

Qiche plus gasoline, trucks and diesel, most of the good cars with 93 use 97 good oil, which is good for the engine of the car.

Look at the engine, generally add more gasoline, 93,

Gasoline: 90 93 97 Diesel: 0 -10 And natural gas!

This depends on the car, some cars can run on 92 petrol, while others can run on 95 petrol. What kind of gasoline is used in the car is recorded in the car manual. Nowadays, many people are keen to use high-grade gasoline, and even regard the label as a standard of fuel purity and quality.

In fact, the gasoline label only indicates the octane number of gasoline, that is, the knock resistance, and has nothing to do with purity and quality. If the engine set to No. 92 oil is hard to use No. 95 oil, there will be a phenomenon of "stagnant combustion", that is, it is not yet the spontaneous ignition point when it is pressed to the end, and the combustion is not complete, which will cause pollution and waste.

It should also be noted that the gasoline of different grades of the car can not be mixed, and the occasional mixing will not have a big impact on the car, but if it is often mixed, the impact on the car is very serious, especially the car engine, which may face an overhaul of the engine. Cars running on 95 gasoline cannot use 92 gasoline or lower, but cars running on 92 gasoline can use 95 gasoline.

From the most intuitive sound:Gasoline engines work on the principle of ignition and are quieter, and good engines are basically noiseless. The diesel engine is compression-ignition, which requires a large compression ratio to compress the diesel fuel, and the piston in the cylinder needs a large force movement, so the noise of the diesel engine is much larger than that of the gasoline car, and the engine without high-pressure common rail and other silencing equipment will basically make a "click" sound after starting.

Precautions. The diesel engine is compression-ignition, so there is no need for ignition devices such as spark plugs, and an extra layer of acoustic panels will be added under the hood and in front of the cab in order to reduce some noise in the cab.

The gasoline engine has a spark plug, and the gasoline pump is generally in the mailbox.

When buying a car, you have already decided whether you want to buy a diesel or gasoline car. The second is that when refueling, the car will generally have a logo on the inside of the fuel tank cap, which is also very clear, what kind of oil to add, how much oil to add.

Hello friends, open the fuel tank cap, what type of fuel will be written on it, and use the car happily.

Generally, there will be a reminder on the fuel tank cap**Note the number of oil and above.

Generally, there will be a mark on the inside of the fuel tank cap.

If you don't know what type of gasoline to add to the vehicle, if you open the lid of the fuel filler, a small label will be pasted inside, prompting the model of refueling, you can find it yourself.

The inside of the car's fuel tank cap is marked with a mark indicating whether it is gasoline or diesel to be filled, as well as the model of the fuel to be filled.

It's all about the same, just go according to the height, the general A-class car is 92, I don't know 95, ** higher, but the same money runs about the same number of kilometers.

As long as you distinguish between gasoline and diesel, there will be no problem if you don't know how many numbers are heightened.

1. Engine oil: Engine oil is the brainchild of the engine. There are many metal parts in the engine that rub against each other, the friction speed is fast, the surface is rough, and the working temperature is as high as 400°C-600°C. Only a qualified lubricating oil can reduce the wear and tear of the engine.

2. Brake fluid: Brake fluid, also known as brake fluid, realizes braking by evenly transmitting pressure, and has four major functions: energy transfer, heat dissipation, anti-corrosion and anti-rust and lubrication. Its replacement cycle is generally long, so in most cases, it is only necessary to check whether its liquid level is in a normal state once in a while.

3. Antifreeze: Antifreeze can make the engine run at normal working temperature, avoid coolant freezing in winter, prevent boiler from boiling in summer, and have an important protective effect on radiators and cylinders, so it should be used all year round.

4. Transmission oil: Transmission oil is an oil product that keeps the gearshift system clean, which can ensure the normal operation of the gearbox and help to prolong the life of the transmission.

5. Power steering oil: Power steering oil helps to reduce the wear of the power steering pump, mainly plays the role of transmitting steering force and buffering, and the bad power steering oil will significantly affect the driving feel and reduce the role of the driver's steering strength.

6. Glass water: remove dust, gum, bird droppings and shellac on the windshield daily.
