What else can you do with the engine oil that the car has exchanged?

Used engine oil is regenerated to produce other ancillary products such as low-standard diesel oil vapor.

The main role of motor oil:

1. Lubrication and wear reduction: between the piston and the cylinder, between the spindle and the bearing, there is a fast 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.

2. 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.

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

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

6. 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.

Waste engine oil can not be used as a lubricant, because it contains metal impurities, dust and other impurities, if it is a high use time or frequency of oil, it may also produce organic acids, gums and other substances, are harmful substances, and can not be disposed of casually, to go through strict **, otherwise there is a great pollution to the environment (1 ton of waste mineral oil can pollute 1 million tons of drinking water). Only unused motor oil can be used as a lubricant. Waste engine oil can be regenerated to produce other ancillary products such as low-standard diesel oil vapor.

It can be used to lubricate other machines. There are also people's **, a large oil drum is 550 yuan. Some people use it to filter and sell it again.

Lubricants, because I see ** rusty, they are all coated with used engine oil.

1. The oil is used to lubricate the piston, piston ring and cylinder, and when the piston moves downward, it will leave a layer of oil film on the cylinder wall.

2. The oil is also used to lubricate the intake valve stem and is sucked into the combustion chamber.

3. During high-speed driving, the diluted components will evaporate, so excessive oil consumption will be found after high-speed driving.

Empirical step: Oil is used to lubricate pistons, piston rings, and cylinders, leaving a film of oil on the cylinder walls as the piston moves downward. When the vehicle slows down, the resulting high negative pressure draws some of this oil into the combustion chamber, and this oil is burned by the hot combustion gases during the combustion process, just like the oil film that is partially left on the cylinder wall.

The oil is also used to lubricate the intake valve stem, which is sucked into the combustion chamber. The hot exhaust gases also burn the oil used to lubricate the exhaust valves. Here are the factors that affect oil consumption:

1. Viscosity of engine oil: The lower the viscosity of the oil, the worse its sealing effect and the more it is sucked into the combustion chamber. 2. The driving condition of the vehicle:

High speeds, as well as frequent acceleration and deceleration, will increase oil consumption.

During high-speed driving, the diluted components will evaporate, so excessive oil consumption will be found after high-speed driving.

Since the new engine is not run-in, more oil will be consumed. The maximum oil consumption given by Toyota during the break-in period is: maximum 1 0l (liter) 1000km (km).

From the above analysis, it can be seen that the inspection of oil level is one of the key items of daily maintenance of vehicles. On the other hand, the oil will become thinner due to the adsorption of water vapor during use, so it is difficult to correctly determine the true oil level when judging the consumption of engine oil. Therefore, even if the oil level is normal, we need to change it regularly according to the requirements of the mileage.

Hope it helps, hope!

The engine oil of the car is mainly to ensure the mechanical lubrication of the car, after use, it will produce the precipitation of dirt and machine wear, and it will affect the operation of the automobile machinery for a long time, so in order to ensure the normal operation of the car, it is necessary to change the car oil regularly.

Only to a certain time must be replaced, if the oil is not changed, a turbidity will affect the driving of the car's engine, driving will be relatively slow, incoherent, the engine is also damaged, so as long as a little turbidity, be sure to change the new oil.

The purpose of changing the engine oil of the car is to better reduce the wear and tear of the car and enhance the power of the car. Keep the pressure of the car stable. In order to better lubricate the parts of the car, the oil will be changed.

The main reasons why oil will gradually deteriorate during operation are:

Combustion by-products: such as moisture, acids, soot, carbon deposits, etc.;

fuel dilution; high-temperature oxidative deterioration of the oil itself;

Dust and metal particles.

These substances are contained in the oil, and the additives in the oil are constantly depleted as they are used. Failure to change the oil on time will significantly reduce the protective effect of the oil on the anti-wear of the engine. Changing the oil not only removes contaminants from the oil, but also ensures that the components in the oil are kept at a reasonable level.

There are many factors that affect a vehicle's oil change. 1. Fuel quality. If the quality of the added fuel is not good, there may be more carbon deposits in the process of fuel combustion, resulting in excessive consumption of automobile oil, and it is necessary to add and replace the engine oil in time, and the engine oil should be selected as reliable as possible.

2. The age of the vehicle. The car has been used for a long time, and the various parts of the car may have different degrees of aging, and the wear and tear will increase, and the consumption of automobile oil will also increase in this case. 3. Road conditions.

The road oil life is relatively long in good road conditions, and if you can't even drive three yards all year round, the owner may have to change the oil for 1000 kilometers. 4. Oil type. Fully synthetic motor oil lasts longer than semi-synthetic motor oil, but it is clear at once.

You can take out the dipstick and smell it, it is best if it has no smell, if there is a sour smell, it means that the oil has deteriorated and the oil should be changed immediately.

Observe the flow state of the engine oil, it is better to be slender and even, if it is large and small, fast and slow, it means that the oil has deteriorated.

In general, industrial vehicles are basically at the limit of maintenance mileage and time (far more than 10,000 kilometers or even more than 30,000 kilometers) will do the simplest maintenance and change the cheapest engine oil.

I think I can change the oil of the car, but only if the owner has the disassembly tools and understands the specific operation process.

The engine is the heart of the car as the engine is to the human body, just as the blood is to the human body. However, unlike blood, engine oil has a self-purifying effect, and after a long time, the engine oil will be mixed with various wastes and need to be released, so it is necessary to replace the oil with a new one.

There are generally three types of engine oil: mineral engine oil, semi-synthetic engine oil and fully synthetic engine oil, and the replacement time of each type is different. Among them, the mileage of mineral engine oil is relatively short, and the oil needs to be changed after 5000 kilometers, but this kind of engine oil is no longer used in many cars; Semi-synthetic engine oil lasts longer than mineral oil, about seven or eight kilometers, and there are more models used; Fully synthetic engine oil is the best of the three engine oils, which can run more than 10,000 kilometers, and it is also the most powerful, more high-end cars, all use this type of engine oil.

Let's take a look at how to change the engine oil.

First of all, we need to correctly select the quality and viscosity level of the lubricating oil and choose the high-quality filter element produced by the regular manufacturer. When changing the oil, turn off the engine when the engine is at normal working temperature, unscrew the oil filler cap, remove the oil drain screw to release the old oil, and unscrew the old filter with a special brand tool.

Immediately after that, we can screw in and tighten the oil filter, and the way to tighten the oil filter is usually to tighten it and then screw it in 3 or 4 turns.

Finally, choose an oil that meets the specifications of the car and pour the appropriate amount of oil into the oil pan. But don't pour it out of the engine, otherwise it will cause carbon deposits, and if you want to be safe, you can use the funnel to fill it.

There is also an important point, that is, the oil level must not exceed the highest scale line, otherwise it will not only increase the loss of internal power of the engine, but also fill a lot of carbon deposits in the long run, and in serious cases, the phenomenon of burning engine oil may occur.

When the oil is added, it is also necessary to start the car, let the engine run for 3 to 5 minutes, and then turn off the engine. Re-draw the dipstick to check the oil level, and raise the vehicle to check the position of the oil pan screw or oil filter for organic oil leakage.

I don't think we can change the oil of the car by ourselves, because it will bring us a lot of unnecessary trouble, and it is not conducive to ensuring the safety of our lives, so I think the oil of the car should not be changed by ourselves.

Yes, but you need to understand the way to change the oil, and you also need to have the skills to change the oil, and when you change the oil, you must choose the right oil.

No, there is a certain danger in doing so, it may affect the life of the engine, and there may be some impurities.

Write the process first, then the problem, and why.

1. Open the oil cap and pull out the oil ruler. (Upstairs said that the synchronous air pressure may not be understood by many people, because the engine is a closed cavity, if only the oil seal of the engine oil pan is unscrewed, due to the effect of atmospheric pressure, the waste engine oil can not be discharged or discharged very little.) The normal operation of the 4S store should at least be covered with a shoulder cloth to prevent the metal on the body from scratching the paint surface or the car from soiling the clothes).

2. Raise the car, or use the ditch if there is a ditch.

3. Unscrew the oil seal (usually a hexagonal bolt), pay attention to the !! The oil is very hot to your hands. Because whether it is driven to the lift or the trench, the engine has just finished running, and the oil itself has the effect of cooling and absorbing a lot of heat from the engine.

It is common for a little mechanic apprentice to get burned in this part. Note at this time: A container is required to hold the exhaust oil.

It's not right to let the oil drain at will. In view of the temperature and oiliness of the oil, the subject chooses for himself. 4S stores generally have special collection containers.

4. Unscrew the filter and remove the gasket. This step is usually done with a special machine filter wrench. Changing the oil without changing the filter is equivalent to not changing.

Because one of the important roles of engine oil is to clean and filter all kinds of waste debris from engine operation into the filter. If you change the oil and use the old filter, the waste debris that has been generated will be recycled back into the engine. The gasket is replaced because the gasket is disposable, and the use of the old gasket and the new filter cannot guarantee a complete seal.

5. After the oil drain is clean (the exquisite 4S shop will blow down from the oil filling port to ensure that the oil drain is clean), the gasket, the filter, and the oil seal.

6. Lower the vehicle with a lift and fill the oil from the oil filler. Generally, different amounts of engine oil are filled according to the different engine displacements.

7. Tighten the oil cap and determine whether the oil is the right amount through the oil ruler.

8. Start the engine, run it a little and then turn off the engine, and check the oil ruler again to see if the filling is appropriate.

9. Insert the oil ruler back in, and you're done.

Question 1: The process of changing the engine oil is actually quite dirty, and it is very easy to stain yourself or your clothes or car;

3: It is troublesome to have no lifts and gutters.

4: The most important problem is that the subject has already explained, individuals cannot dispose of waste engine oil, waste machine filters, and cloth contaminated with waste engine oil used during cleaning. In a regular 4S store, you must sign an agreement with a unit with relevant disposal qualifications to deal with the three things mentioned above on a regular basis.

If you dispose of it privately, there will be a very serious fine. Don't underestimate the waste engine oil, it will pollute the environment, and it will burn if the temperature reaches a certain level (**, the general temperature cannot ignite the engine oil). Somewhere in Beijing, there was an illegal den for collecting waste engine oil, caused by improper safety facilities, and next to it was a furniture factory, which burned people's furniture.

Now the environmental protection department is very strict about this.

Can you do a car oil change by yourself? Learn in a few minutes without going to the 4S store to spend money 01

In the process of engine oil, additives are gradually consumed, combustion produces stupid pollutants, mixed with engine oil to produce sludge, deposition for a long time, these dirt will not only accelerate engine wear, but also lead to engine rust corrosion, loose ruler heat and other serious consequences. Therefore, changing the engine oil in time is the best care for the engine. The role of motor oil for the engine is:

1.Lubrication: The main function of Lingshenqing engine oil is to lubricate it, which can form an oil film on the surface of the metal parts of the engine and reduce the wear of the metal surface.

2.Cleaning: Decomposes the sludge and deposits generated during the use of the engine to keep the inside of the engine clean.

3.Anti-rust: neutralize the acidified substances generated during use in the engine and form an anti-rust and anti-corrosion layer to avoid rust and corrosion of metal parts due to oxidation.

4.Sealing: The gap between the piston and the cylinder block is closed to maximize fuel combustion and fuel efficiency.

5.Cooling: Disperses the high temperatures generated by engine wear and protects engine components.
