When buying a car, how to tell what kind of oil the car burns!

Hello, if you are a second-hand car, the easiest way is to see if there is any blue smoke from the exhaust, if there is so, then it must be burning engine oil.

Blue smoke from the exhaust pipe is burning engine oil. Also remember to check the dipstick often.

Hello, the vast majority of family cars now burn gasoline. Generally naturally aspirated engines with 92-93. Some turbocharged engines use 95 97 fuel caps and instructions have prompts.

Hello, you mainly look at the number on the fuel tank cap, almost all of the models on the lid have oil written on them, or look at the engine.

Hello, there will be a reminder on the manual and inside the front hood that you add 92 or 95 gasoline, look for it.

Today's cars are nothing more than gasoline cars and diesel cars, and gasoline cars are the mainstream. Generally, when choosing a model, the diesel engine or gasoline engine will be marked, so rest assured.

Normally, if you buy a car, even if the store staff doesn't tell you, you can see the car by yourself, and the fuel standard is also marked on the big green book, or the vehicle configuration parameters are introduced on the Internet.

When buying a car, it is generally marked on the fuel tank cap or manual of the car what gasoline needs to be filled

Generally, there is a recommended gasoline designation. It is also possible to choose 95 gasoline directly. Good anti-explosion performance.

Hello, your vehicle certificate is there, and you can refer to the specific configuration data fuel number.

Depending on the model, it is generally gasoline.

Hello, the general turbine engine can choose 95 fuel marking, and the self-priming engine can use 92.

Ask the person selling the car directly.

It must be gasoline, what kind of oil could it be.

Hello, on the certificate, the body will be marked with the recommended gasoline number, just take a look.

This is generally marked, and the general car certificate also clearly indicates what kind of oil to add.

Hello, generally speaking, there are prompts on the fuel tank cap of the car, or you can ask the salesman directly.

Generally speaking, you can check the amount of gas burned in the car, and the location of his mailbox also indicates what number of gasoline you put in.

You are talking about the fuel label, you can refer to the certificate of your vehicle, the specific indication.

Hello, this one is very simple, you can open the fuel tank cap and look at the sign there.

Hello, the engine oil filling of this car is indicated, and the fuel tank cap is also available.

Distinguishing what kind of oil a car burns can be judged by the engine, and you can generally know the model.

How to determine whether a car uses gasoline or diesel:

1. Listen to the sound of the engine. The louder is the diesel engine, and the louder is the gasoline engine.

2. Open the fuel tank cap or smell the exhaust gas, the diesel smell is strong and pungent, and the gasoline smell is lighter.

Gasoline treatment method:

1. Emergency treatment of leakage. Quickly evacuate the personnel in the leakage and pollution area to a safe area, isolate them, strictly restrict access and cut off the source of fire. Emergency responders are advised to wear self-contained positive pressure breathing apparatus and firefighting protective clothing.

Cut off the source of the leak as much as possible. Prevent access to restricted spaces such as sewers and drainage ditches.

Small leakage: Absorbed with sand, vermiculite or other inert materials. or, if it is safe to do so, burn it on the spot.

Massive leakage: building embankments or digging pits to contain them; Cover with foam to reduce vapor hazards. Transfer to a tanker or special collector with an explosion-proof pump** or transport it to a waste disposal site for disposal.

2. Protective measures. Respiratory protection: Generally, no special protection is required, and self-priming filtering gas masks (half masks) can be worn for high-concentration exposure.

Eye protection: Generally, no special protection is required, and chemical safety glasses can be worn when exposed to high concentrations. Body Protection:

Wear anti-static overalls. Hand protection: Wear anti-benzene and oil-resistant gloves.

Others: Smoking is strictly prohibited on the work site. Avoid repeated contact over a long period of time.

Burning a few oils refers to how many liters of oil the car consumes after driving 100km, and one liter of oil is one liter of oil; Another way of saying it is to divide the fuel consumption of 100km by 100km, which is how much is a kilometer.

Fuel-saving methods for automatic transmission cars:

Wait for the red light to hang the n gear.

Because it is hung in "D" gear, it will increase the friction of the clutch. So the right thing to do: when waiting for the red light, hang the "n" gear (i.e. neutral).

The advantage of this is that it is "fuel-efficient". When waiting for the red light, hang in the "n" gear, so that the owner's feet can also be removed from the brakes, so as to get proper stretching and reduce driving fatigue.

Avoid braking suddenly.

Emergency braking is usually used under the premise of safety crisis, but it is also very fuel-intensive. In the case of safety issues, it is recommended that you still concentrate on driving, and at the same time keep a certain distance from the car in front of you and do not brake suddenly.

Make good use of the glide.

Automatic transmission models should never be hung in "N" gear when driving, but refer to the use of the inertia of the vehicle speed, release the car accelerator pedal, let the car slide by itself, so that coasting can save a certain amount of fuel. Most automatic transmission models, at 60 km/h, can normally coast for about 200 meters, and the speed will drop to about 40 km/h, which is available. For example, when descending from the elevated road, you can completely release the accelerator in advance and let the car slide to the intersection by itself.

The right period for air conditioning and window opening.

Under normal circumstances, when the speed is not fast, the wind resistance value of the window will not be large enough to exceed the fuel consumption of the air conditioner, generally less than 85km, and the window is the best choice; Exceed this speed, choose to turn on the air conditioner.

The number of fuel burned by the car refers to the fuel consumption per 100 kilometers, that is, the amount of fuel (liters) required for the car to travel 100 kilometers. The introduction of fuel consumption per 100 kilometers is as follows:1

Fuel consumption per 100 kilometers refers to the fuel consumption of a car driving 100 kilometers on the road at a certain speed. It is a theoretical indicator of the vehicle. 2.

100 kilometers of fuel consumption is the manufacturer in the objective environment, with the vehicle chassis installed in the dynamometer measured value into speed parameters, in the specified speed driving, calculated the model of the theoretical experiment 100 kilometers fuel consumption data. 3.Calculation method:

The actual method of calculating fuel consumption per 100 kilometers: x u002f100 = 50 u002f600, x is the actual fuel consumption of 100 kilometers we seek, and the right side of the equation is the fuel consumption of 50L for 600 kilometers of the vehicle. Solve the equation, x=50 100 u002f600.

Answer: x?, so the actual fuel consumption of the car is about 100 kilometers Now many vehicles will show 100 kilometers of fuel consumption, but the computer calculation, there will be a certain error, so if you want to accurately know the fuel consumption of gasoline, you can calculate it yourself.

Summary. Hello, I didn't see **. Generally speaking, diesel cars burn diesel, and gasoline cars burn gasoline.

Hello, I didn't see **. Generally speaking, diesel cars burn diesel, and gasoline cars burn gasoline.

Hello, some cars like this are petrol and some are diesel. You need to listen to the sound, because the diesel engine is a compression type ignition with large pulling force, efficiency or forest annihilation, and the sound is domineering. Gasoline cars are spark plugs that ignite with little sound.

Diesel cars do not have spark plugs. The fuel tank cover shirt was opened, and the logo was written on the back of the mailbox, Diesel is diesel. 95 is gasoline.

The above are the ways to test whether the car is a diesel car or a gasoline car. You can't see it just by looking at **.

First of all, the oil added to the vehicle will be consumed more or less, but it is obviously not an obvious problem, generally speaking, it is normal to consume 1 liter of engine oil every 5000 kilometers, and it is necessary to pay attention to it if it exceeds this standard, to see if the following situations occur.

1. The inside of the exhaust pipe is very dark.

Wipe the inner wall of the exhaust pipe first, and wipe it again after a week, if you find that the exhaust pipe is very dark, it means that the vehicle has the phenomenon of burning engine oil.

2. Blue smoke emits when the cold car starts in the morning.

Pay attention to the exhaust pipe outlet when the cold car starts in the morning, if the exhaust pipe emits blue smoke when it is just started, it means that the vehicle burns engine oil, this method is best completed by two people, one person starts the vehicle, and the other person is responsible for observing. This is because the blue smoke emits for a short period of time and only appears after the vehicle has been left for a long time.

3. Blue smoke emits when the throttle is large.

When the vehicle accelerates sharply or hits the throttle on the spot, there is a phenomenon of blue smoke, and there is basically no idling, which indicates that the vehicle burns oil, and it is more serious, and it should be repaired as soon as possible.

4. Blue smoke comes out of the engine oil injection port.

If the vehicle starts to emit blue smoke from the oil inlet in addition to the exhaust port, it means that this symptom has reached the middle and advanced stages, and the burning of engine oil is very serious, and you need to seek medical attention as soon as possible to avoid causing more damage.

Poor sealing is the root cause of burning engine oil!

1. Burning engine oil in a cold car: When the car is started for the first time in the morning, when the temperature of the car is not completely warmed up, the engine exhaust pipe emits a lot of blue smoke, but it is normal after the car is warmed.

Reason: This is caused by the aging of the valve oil seal. Due to the decrease in temperature, the valve oil seal made of rubber becomes stiff and cannot be completely sealed, and the oil leaks from the valve into the combustion chamber and burns.

2. Burning engine oil in a hot car: After starting the car in the morning, there is no blue smoke discharge, but the engine still burns oil.

Reason: Due to the poor sealing of the piston ring, the oil directly enters the combustion chamber through the piston ring leakage under the action of the oil pump, and there is a phenomenon of blue smoke from the exhaust pipe.

To sum up, the root cause of burning engine oil can be boiled down to:

Due to long driving time, improper maintenance, oil quality and driving habits, there is too much carbon deposit inside the engine, and the cylinder wall and piston are seriously worn, so that the gap is too large, and the original sealing is lost, and the oil is channeled to the combustion chamber through the gap for combustion. Recommend Germany's Marty's C+M to perfectly solve the problem of burning engine oil in automobiles!

Burning engine oil is when the engine oil enters the combustion chamber and participates in combustion together with the fuel, and blue smoke is emitted from the exhaust pipe. There are two main types of oil that enter the combustion chamber**. First, from the cylinder head. The valve oil seal is aging and the sealing performance is deteriorating, causing the oil to penetrate into the combustion chamber.

The engine is stationary for a long time, and the oil flows into the cylinder from the valve oil seal, starting the engine, and the exhaust pipe has a thick blue smoke, that is, the cold car burns the engine oil. In addition, the valve guide is abrasive, resulting in an increased gap with the valve and oil entering the combustion chamber. Second, from the cylinder block.

Excessive piston wear, damage to the piston ring groove, weakened elasticity of the piston ring or excessive wear or even failure, will lead to poor sealing, splashed oil into the combustion chamber, participate in combustion, and manifest significantly during acceleration. In addition, if the cylinder barrel is worn too much or unevenly, the excess oil on the piston ring cannot be scraped off, which will cause the oil to burn.

Suggestion: The more common and better engine oils on the market are Rheinland organic molybdenum engine oil (fuel saving more than 5%), Mobil, Shell, Total, etc., use less unknown engine oil brands to prevent engine damage.

Check the color of the exhaust gas discharged from the exhaust pipe of the vehicle, and the color of the exhaust gas is transparent and colorless smoke when the engine is working normally. If the color of the exhaust gas coming out of the SHU exhaust pipe is blue smoke, it can be judged that the vehicle has a fault of burning engine oil.

The severity of the oil burner fault can also be judged based on the concentration of the exhaust exhaust blue smoke from the exhaust pipe.

The blue smoke is very faint, indicating that the fault of burning the engine oil is not very serious, indicating that it has just happened.

The blue smoke is very thick, indicating that the fault of burning the engine oil is serious, indicating that the fault of burning the engine oil is already serious.

1. Whether the exhaust pipe emits blue smoke:

When the car starts in the morning, look at the exhaust pipe of the car to see if there is blue smoke coming out, if you find that the exhaust pipe has blue smoke coming out, it means that the car has the phenomenon of burning engine oil, you can find two people when judging by this method, because the time of blue smoke from the exhaust pipe of the car is relatively short, if you start the car, you can not check it in time, it is difficult to detect.

2. Look inside the exhaust pipe

It is a relatively simple method to judge the phenomenon of burning engine oil through the exhaust pipe, after the car is turned off, observe the situation on the inside of the exhaust pipe, if there is some black precipitate on the inside of the exhaust pipe, it means that the performance of the engine is not good in the process of running the car, and some oil is mixed in, and the phenomenon of burning engine oil appears, and the amount of black precipitate is used to judge whether the burning of engine oil is serious.

3. Whether the spark plug has carbon deposits

The carbon deposition of the spark plug in the normal use process is relatively delicate, and the number is relatively small, if the car burns the oil, the carbon deposition of the spark plug will be more obvious, and the method of judging the burning of the oil through the spark plug is relatively troublesome, you can go to a professional 4S shop or a maintenance shop to deal with it.

You fill up the tank first, and you know the volume of your car's fuel tank, right? Run 100 kilometers, go to the gas station, refuel, fill up until you fill up, and see how much fuel you have filled, and the number displayed is the approximate fuel consumption of your car for 100 kilometers.
