According to the provisions of the "National Hazardous Waste List", waste engine oil is a hazardous waste, which is generally regularly discharged by relevant departments (qualified units) and is not discharged. Generally, the waste engine oil produced by 4S shops and maintenance plants is to be subjected to the highest level, and it is also under the supervision of the relevant parts.

Generally, waste engine oil can produce gasoline or diesel after precipitation distillation catalytic cracking treatment, and then waste engine oil can be used as a separating agent for building templates and waterproof coatings.

A small amount of the ** engine oil from informal companies goes to the factory for reprocessing, and most of it is used to make counterfeit and shoddy engine oil. As long as an additive is added and refined, the used engine oil can be turned into a shiny genuine engine oil, which can almost be real from the outside. <>

No, or change the oil, or not damage the car, with a good oil is better for the engine and power, my new car second insurance began to use GT magic red oil, there is a liquid molybdenum formula in the anti-wear effect is very good, the high-speed sound is very stable, the power has been very stable, and the throttle is also very light.

This is not good for the car, you can change the magic red oil, more than 15,000 kilometers of replacement cycle, and the magic red oil is added with liquid molybdenum additives, anti-wear protection is very good, the power is improved too much, you can drive to 10,000 kilometers, the power is very stable. The original engine oil used before was out of power after 5000 kilometers.

For personal use: It is best to change the oil with a new one.

Commercial: Don't do this kind of lack of morality anymore!!

Filtration can only remove physical impurities, not restore spoiled oil to acceptable quality.

Hello, this needs to be refined in a special place.

After driving the car to the designated operating place, turn off the engine for an hour or two to let the oil all return to its place and settle. Then lift the front wheels of the car, or pump oil with a tube. Waste oil residue has no effect on the engine, as long as most of the old oil is released when the oil is changed.

At this time, you should go to a professional 4S shop to operate, you can put the engine in a running state, and then after reaching the temperature, lift the car with a jack, open the oil drainer, let the oil drip for a while, and then put the new oil in.

You can open the valve of the oil and turn the oil tank sideways so that it can be put clean. The best way is to clean it with clean water, place the fuel tank on its side, shake it, and discharge it by tapping in the process of dumping.

In fact, we must transport the engine in advance, and then let the engine reach the corresponding temperature, so that we can put the oil, we must wait for some more time, and then add new oil after the oil is completely gone.

First of all, turn the engine to the required level of work, prepare the container of old engine oil under the oil pan, and choose the oil filter element suitable for your car according to the user, the best way is to let a professional person do it.

First of all, the motor is operated to reach the working temperature. Then use a jack to jack up the vehicle and slowly unscrew the oil drain bolt to let the oil drip for a while. Pour a little more new oil into it and put it out, so that the dirty oil inside is clean.

Engine oil is the lubricant used in engines. Consists of base oils and additives. The density of the engine oil is about to be able to lubricate and reduce wear, assist cooling and cooling, seal and leak prevention, rust and corrosion prevention, shock absorption and cushioning for the engine.

It is known as the "blood" of automobiles. 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.

Changing the engine oil and oil filter machine must do the necessary thing for maintenance. First, let's understand the importance of these two things.

1. Engine oil is the lubricating oil for engine operation. It can lubricate, clean, cool, seal, reduce wear and other functions of the engine. It is of great significance to reduce the wear and tear of engine parts and extend the service life.

2. The oil filter element machine is a part of the oil filter. Engine oil contains a certain amount of gum, impurities, moisture and additives; In the process of engine work, the metal chips generated by the friction of various parts, the impurities in the inhaled air, and the oil oxides are all the objects of the oil filter element. If the oil is not filtered and goes directly into the oil circuit, it will have a detrimental effect on the performance and life of the engine.

Oil filters are not recommended for reuse after cleaning. This is determined by the specificity, precision and complexity of the oil filter, as follows:

1. Particularity: oil filter, also known as oil grid. The function is to filter out the metal grinding debris, dust and oxidized carbon deposits and colloidal sediments generated during the working process of the engine, so as to keep the lubricating oil clean and extend its service life.

The oil filter should have strong filtration capacity, low flow resistance, long service life and other properties. Failure to meet these requirements can cause irreversible damage to the engine;

2. Precision: The requirements for the oil filter are: a. filter out all particles greater than 30um b. reduce the particles that enter the lubrication gap and cause wear (less than 3um-30um) c. the oil flow rate meets the oil demand of the engine d, the replacement cycle is at least longer than the life of the oil e, the filtration accuracy meets the requirements of protecting the engine and reducing wear f, the ash holding capacity is large, suitable for harsh environments g, can adapt to higher oil temperature and corrosive environment h, The lower the pressure difference when filtering the oil, the better, so as to ensure that the oil can pass smoothly;

3. Complexity: The oil filter is composed of filter paper, sealing ring, and a variety of valves: a. Filter paper

The oil filter has higher requirements for the filter paper than the air filter, mainly because the temperature of the oil varies from 0 to 300 degrees, and the concentration of the oil also changes accordingly under the drastic temperature change, which will affect the filtration flow rate of the oil. The filter paper of a high-quality oil filter needs to be able to filter out impurities under drastic temperature changes while maintaining sufficient flow rates. b. Rubber sealing ring:

The filter seals of the high-quality motor oil are made of special rubber and guarantee 100% oil leakage. c. Backflow suppression valve: when the engine is turned off, it can prevent the oil filter from drying out; When the engine is re-ignited, it immediately creates pressure and supplies oil to lubricate the engine.

Millions of car purchase subsidies.

The oil filter should be replaced, and the replacement of the automobile oil filter is not subject to time, but to the mileage driven, and it can be replaced for about 5000 kilometers. However, if it is not up to 5000 kilometers, as long as the oil is changed, the filter is generally replaced together.

What the air filter does:

1. The automobile air filter is mainly responsible for removing particulate impurities in the air. When piston machinery (internal combustion engines, reciprocating compressors, etc.) is working, if the inhaled air contains dust and other impurities, it will aggravate the wear and tear of the parts, so it is necessary to install an air filter;

2. The air filter is composed of two parts: the filter element and the shell. The main requirements of air filters are high filtration efficiency, low flow resistance, and the ability to be used continuously for a long time without maintenance;

3. The automobile engine is a very delicate part, and the smallest impurities will damage the engine. Therefore, before the air enters the cylinder, it must be finely filtered by the air filter before it can enter the cylinder. The air filter is the patron saint of the engine, and the quality of the air filter is related to the life of the engine;

4. If the dirty air filter is used in the car, the engine air intake will be insufficient, the fuel combustion will be incomplete, and the engine will be unstable, the power will decrease, and the fuel consumption will increase. Therefore, it is essential for the car to keep the air filter clean.

The oil can be mixed with baking soda and a little cold water to make a thick paste and applied to the stain to clean. The oil can also be washed using organic solvents such as alcohol, gasoline, dish soap, etc.

The following is a brief introduction to the specific two washing methods:

Cleaning method 1:

Make a thick paste with baking soda and a little cold water and apply to the stain; Let stand for 30 minutes and allow to dry completely before removing the baking soda. Mix the laundry detergent with an equal amount of baking soda and wash it with water on high heat (the temperature that the object can withstand).

Cleaning method 2:

Sprinkle baking soda powder first to absorb the oil stains on the clothes; Do not wet your clothes, apply some enzyme laundry detergent on both sides of the stain and let it sit for a while; Put the laundry in a washing machine with enzyme laundry detergent and wash it at the highest water temperature that the laundry can withstand;

CAUTION: Do not use petrochemical solvents to clean the oil, as the oil is highly flammable. Don't tumble dry, even if you've rinsed with water, and be sure to let the laundry air dry.

How much do you know about engine oil:

Engine oil is a mixture of several hydrocarbons, is organic matter, according to the principle of similar miscibility, we can also use organic matter to dissolve engine oil, but it is best that the organic matter we choose can also be soluble in water, so as not to cause secondary pollution. The most convenient thing is to choose alcohol, which is soluble in both organic solvents and water. Of course, the higher the alcohol concentration, the better, preferably anhydrous alcohol.

If it's a little bit, wash it with wind oil essence (the small round one, the red one, and the inside is yellow), it's easy to clean, I've tried it many times, and any oil stains and the like can be removed. Apply a little bit of wind oil essence to the place where the clothes get the engine oil, let it sit for a few seconds, and then wash it off with the laundry, and it is simple.
