How do I know if the oil in my car is still working?

The detection method of touching with your hands and smelling with your nose is actually not so professional and very inaccurate. The really simple and effective test strip test method, which can be purchased online, 8 yuan and 100 pieces of test strip, only 8 cents for a test.

How do you test it?

After stopping for another ten minutes, take out the oil dipstick, drop a drop of oil in the center of the filter paper, then lay the test strip flat on the hollow object in the middle, wait for 6 hours, and finally observe the oil spots left by the oil on the test paper. Then observe the condition of the oil spots.

1. The oil spot is divided into three layers from the outside to the inside: oil ring, diffusion ring and sedimentation ring.

2. The wider the oil ring, the smaller the oxidation of the oil.

3. The wider the diffusion ring, the longer the remaining life of the oil.

4. The lighter the color of the deposition ring, the less impurities in the oil.

5. So under what circumstances should we change the engine oil?

The boundaries of the three rings are clear, and they should be replaced as soon as possible.

The oil ring is gone, and only the sedimentation ring and diffusion ring are replaced!

Only the darker deposition rings are replaced! Otherwise, the engine is going to be finished!

Summary: The oil change interval of each car owner depends on the limit value of the oil and the filter, so it is recommended to choose the filter that matches the oil, which is an important matter to extend the oil change cycle. To put it simply, it is a good engine oil, and it should be equipped with a good machine filter.

The limit value of the engine oil is related to the number of revolutions of the engine, and when a certain amount of work is reached, the oil will reach the end of its life, which is the time to change the oil. If you usually use less cars, you should determine the oil change interval according to the oxidation cycle of the oil, and it should be replaced in half a year.

Hello. Pull out the dipstick and bring the oil drops to the toilet paper to see the color of the oil. If the oil is, yellow with a little black, then it can continue to be used, at least 3,000 kilometers.

If the oil has turned black, it is recommended to replace it. If the oil has turned brown and has lost its viscosity, it must be replaced. Some of the colors are golden yellow, black and brown.

Automobile engines have an oil scale, pull out the oil scale to check the oil viscosity and color.

However, this requires expertise. Personally, it is better to change the engine oil as required.

If you know, just look at the oil dipstick, whether the oil in it is sticky or black, and then ask the maintenance personnel when you go to change the oil, what kind of oil needs to be changed.

Buy oil filter paper online, judge whether the oil is normal according to the color ring, and judge the method.

Hello, the current number of people consulted may not reply in a timely manner, if it is a vehicle failure problem, it is recommended to use the computer to detect the specific cause of the failure, search for "car master" can consult car problems at any time, 24 hours ** answer.

Identification method of burning engine oil:

1. Cool car burning oil: Every morning when the car is changed for the first time, there will be a relatively thick blue smoke discharge from the rear exhaust pipe. After a while, the blue smoke disappears, and there is generally no similar situation on the day.

2. Burn engine oil when accelerating: When the driver slams on the accelerator or steps on the accelerator when the vehicle is moving, a large amount of blue smoke is discharged from the exhaust pipe, and when the driver slams the accelerator when the vehicle is driving, the driver can see the blue smoke from the reflector on the exhaust pipe side.

3. Fill the vehicle with the phenomenon of "burning engine oil" with engine oil, let the owner go to the maintenance station to weigh the oil filter after driving 1000 kilometers, and then fill up the engine oil, and then let the owner drive 1000 kilometers. Repeated 3 times, to obtain an average value, after the run-in period of normal oil consumption can generally reach 1000 kilometers liters, if the standard is exceeded, there is a situation of burning oil.

Precautionary measures for burning engine oil:

1. Use high-quality engine oil for the hand destroyer key

Engine oil is very easy to corrode and age in a long-term high temperature state, resulting in the oil film becoming thinner, and it is easier to escape to the combustion chamber to participate in combustion, so the use of high-quality engine oil can greatly delay this phenomenon.

2. Pay attention to the cleanliness of the fuel circuit

Fuel in the combustion process is indispensable to produce carbon deposits, and carbon deposits are the root cause of some car failures, such as the aging of valve seals, piston wall clearance, etc., all have a direct or indirect relationship with the formation of carbon deposits, considering the relationship between domestic oil products, it is necessary to borrow Bi Qiaozhu high-quality engine oil and (PNF) fuel additives to achieve, which is also the key to achieving no dismantling and repairing to solve the problem of burning engine oil.

You can take a look at the oil lamp on the dashboard, if the oil lamp turns on, there will be a crack in the mind because the car has no oil. If your valve is loud, it's because there is no oil and you need to refill it immediately. There is this kind of banging sound in the engine source, also because there is no engine oil.

The oil light on the dashboard is on, the water temperature is high, and the sound of the valve is relatively small, so the oil is used up.

The car's oil lamp will turn on, the valve will sound, and the water temperature will be relatively high.

In general, the oil light on the dashboard will turn on, the water temperature will be high, the valve will ring, and there will be a knocking sound in the engine sound.

It can be judged by the oil dipstick and the oil pressure warning light.

The oil has bubbles.

The oil turns black and brown.

Touch it with your hand and the viscosity will become thinner.

In these cases, it will need to be replaced.

1. Observe through the oil test strip.

Go to the Internet to buy oiled paper, 9-11cm diameter slow qualitative test strips on the line, 100 sheets of a box** is about 9-11 yuan. Drop a drop of oil on it, let it sit overnight, and see how it goes the next day. If the edge between the diffused oil ring, sedimentation ring, and diffusion ring is stiffer, the more the oil performance will be decayed.

That's when the oil needs to be changed.

2. Replace according to the driving feeling.

To put it simply, it's all about feeling. The performance of the engine oil has a shelf life, when the acceleration is slow, it means that the "shelf life" of the oil has arrived, if the oil change finds a significant increase in power, it means that the mileage of the last oil change is a little too long. Next time, you can properly advance 500 kilometers, so that you can find a more accurate mileage for changing the oil 1-2 times.

The time when the car oil should be changed is as follows

1. The replacement cycle of different types of engine oil is different.

Mineral oil: 5000 km or 6 months.

Semi-synthetic oil: 7500 km or 6 months.

Fully synthetic oil: 10,000 km or 12 months.

1) The oil quantity should be slightly lower than the scale on the oil dipstick, and do not overfill. Each model has a different capacity, so the number of liters of oil added is different, as long as it is lower than the scale on the dipstick.

2) Adding more oil is a misoperation, if you find that the oil has been added, it is best to entrust the car maintenance center to release it.

In general, the following four elements should be paid attention to when choosing engine oil:

1. The selection of engine oil should be selected according to the requirements of the engine, and it is not necessary to use too high-grade engine oil on the engine with lower requirements, nor can the lower-grade engine oil be used on the engine with higher requirements.

2. Multi-grade oil should be selected as much as possible, because multi-grade oil has a good protective effect on the engine due to its saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

3. The quality of some domestic brand-name engine oil is quite good, and it is much lower than that of similar imported products, so it can be used with confidence, and there is no need to blindly pursue "foreign oil".

4. If the engine is in good condition and the temperature is low in season, the oil with low viscosity should be used as much as possible to make the oil circuit smooth. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.

Hello, I come to your problem, this fault is more complicated, it is recommended that you go to the nearest 4S shop, let the professional staff diagnose you, the fault of the car is not a trivial matter, and I hope you pay more attention to it, all the way safe.

Stop and extinguish the fire for half an hour on the flat ground, pull out the oil dipstick, wipe off the oil stains on the oil dipstick with a clean soft cloth, insert the oil dipstick, pull out the oil dipstick again, first see if the color is normal, and then look at the oil volume, the normal oil quantity should be between the lowest scale and the highest scale, below the lowest scale should be replenished in time, and some should be released if the maximum scale is exceeded. Normal channel maintenance of the vehicle, the oil will not be much.

Generally, in the flame-out state, check the oil, first of all, the oil level is normal, and then check the cleanliness and taste of the oil, as long as the oil level is normal, not charred black, you can continue to use.

1. The oil spot is divided into three layers from the outside to the inside: oil ring, diffusion ring and sedimentation ring.

2. The wider the oil ring, the smaller the oxidation of the oil.

3. The wider the diffusion ring, the longer the remaining life of the oil.

4. The lighter the color of the deposition ring, the less impurities in the oil.

5. So under what circumstances should we change the engine oil?

The boundaries of the three rings are clear, and they should be replaced as soon as possible.

The oil ring is gone, and only the sedimentation ring and diffusion ring are replaced!

Only the darker deposition rings are replaced! Otherwise, the engine is going to be finished!

Paper house on this inspection hints that there is a standard, it has a scale, you can look at the manual intelligent manufacturing. If you really can't reach the scale, it's not good. Hey, for this oil problem, uh, his pool is very high.

Well, he's going to get oil up when he's at the bottom line. If, uh, if I am at a loss, it's not good for the machine.

Automobile oil sorting skills.

Please look for your car's manual, each car may be in a different location, please look for the signs.

Generally, you can look at the oil gauge or the dipstick.

The organic oil indicator light on the side of the instrument, the general light is off, if the light is on, it means that the oil is missing or too much oil.

Isn't there a gasoline gauge in the driver's seat?

The engine is the heart of the car, and there are many metal surfaces in the engine that rub against each other, and these parts move fast and in a poor environment, and the new technology can be used to make natural gas into crystal-pure, fully synthetic base oils, and on top of this, a unique power cleaning technology is added to create a lubricant with superior cleaning and protection properties.

The engine has an oil scale, as long as the lower end of the word scale between the upper and lower lines. The normal mileage of engine oil is divided into 5,000-10,000 kilometers according to different brands, and those that are not used for a long time should be maintained according to the time marked in the manual.

Stop and extinguish the fire for half an hour on the flat ground, pull out the oil dipstick, wipe off the oil stains on the oil dipstick with a clean soft cloth, insert the oil dipstick, pull out the oil dipstick again, first see if the color is normal, and then look at the oil volume, the normal oil quantity should be between the lowest scale and the highest scale, below the lowest scale should be replenished in time, and some should be released if the maximum scale is exceeded. Normal channel maintenance of the vehicle, the oil will not be much.

The lower mark of the oil scale is two-thirds of the way up to the upper mark.

Never lower than the lower scale line, once lower than the lower scale line, the oil pressure will be too low, the oil lamp will be lit, the engine lubrication system will fail, and in serious cases, it will cause the engine to pull the cylinder.

The engine oil should not be higher than the upper scale mark, otherwise it will cause the oil pressure to be too high, the engine oil will be burned, and the engine power will be poor.
