When do you need to add engine oil or fuel additives for car maintenance?

Yes, the use of new cars, focusing on maintenance. Gums, acids, and sulfides in fuel are easy to form deposits at high temperatures, which accumulate in fuel injectors, valves, and combustion chambers, resulting in a decrease in engine working conditions, an increase in fuel consumption, a decrease in power, and a deterioration in exhaust emissions. Additives are used in new cars to prevent the formation of deposits and keep the engine clean.

If you ignore the presence of carbon deposits, it can slowly eat away at engine power, reduce fuel economy, worsen emissions, and lead to a series of engine failures. Fuel additives can help fuel systems perform they can be trusted for a long time. It removes carbon deposits, boosts power, saves fuel, reduces noise and prevents fuel-induced engine failures.

Car maintenance chemicals protect the engine by cleaning the oil circuit, stabilizing fuel, reducing carbon deposits.

Before purchasing and using fuel additives, we must see clearly the function and use of the product, do not think that all additives are a function can be added at will, resulting in unnecessary waste, the main role of additives is to use strong surface activity, drill into the pores of carbon deposits, destroy its structure, and gradually dissolve these carbon particles from the metal surface, and fuel fuel combustion at high temperature through exhaust discharge. Effective fuel additives are not corrosive, such as PNF fuel additives, will not clog ternary, and have high safety.

If you are worried about using inferior quality fuel, such as driving and the oil is uncontrollable, you can immediately use PNF cleaner to break down the oil colloids and impurities. Minor jitter at idle speed that eliminates the fault of the accessory can also be used directly with PNF cleaner.

Before using fuel additives, you should carefully read the instructions of the product matching, and do not think that the more fuel additives you add, the better, because if you add less, at most the additives will not play the role they should have, but adding more is likely to affect the performance of the fuel, and even cause damage to the engine.

Whether the vehicle needs to change the engine oil can be identified by the following 4 methods:

1. Smell the smell, draw the oil dipstick close to the nose and smell, if the strong sour smell means that the oil has deteriorated and should be replaced.

2. Hand twist the old engine oil, grind it repeatedly with your thumb and index finger, and replace it with quality hand lubrication, less grinding chips, poor viscosity of friction impurities, and even astringency.

3. To distinguish the color, take a clean white filter test paper (with a little facial tissue), drop a few points of the old engine oil paper standby oil leakage quality engine oil powder, dry it by hand, smooth and yellow infiltration band is clear dark black and brown impurities, which should be replaced.

4. Light, take the oil dipstick and hold it 45 degrees, and observe the oil droplets clearly to see the oil and drip the grinding debris, which should be replaced.

There will be an oil dipstick next to the engine, and there are two scale marks at the bottom of the dial, and there is no problem with the oil level between the two scale marks, if it is below the scale mark, it needs to be added.

It is advisable to add engine oil to the middle of the upper and lower limits of the oil dipstick. Try not to be lower than the middle, because the high temperature of the engine at high speed can make the oil thinner, if the amount of oil is less will reduce the lubrication effect, a little more in the middle is okay, but never add the upper limit of the oil dipstick, so the damage to the engine is great.

Precautions for adding oil.

The engine oil used in automobiles generally contains a decomposing agent, which can wash off the adhesive film and black carbon deposits attached to the piston and disperse them in the oil to reduce the formation of engine temperature precipitation, so the color of the lubricating oil is easy to turn black after a period of use, but the oil at this time is not completely deteriorated.

Theoretically, the oil change is decided according to the mileage of the vehicle, which is subject to the vehicle driving about 5000 kilometers. Of course, if you observe that the color of the engine oil is severely dark, it means that the oil should be changed.

The reasons for oil consumption include aging crankcase oil seal, poor crankcase ventilation, oil consumption will increase if the engine speed is too high, serious wear of the engine cylinder liner, low viscosity of the added oil, serious wear of the inlet guide, and excessive clearance between the piston and the cylinder.

For when to add oil to the car, many friends are still insisting on changing the oil for 5000 kilometers, in fact, according to whether the vehicle acceleration will become sluggish, the power will be insufficient, if there is a means that the oil should be changed.

"Engine oil" is a necessary lubricant to ensure the normal operation of the engine, its specific role is to lubricate metal parts, reduce the friction between parts, take away the huge heat generated by the engine when doing work, clean the fine metal debris produced after wear, as well as sealing, shock absorption, rust prevention and other functions.

However, when filling the oil, it should be noted that the amount of oil should not be too much or too little, and should be between the "low" and "full" positions of the dipstick.

1. Too much oil.

For vehicle engines, oil is indispensable. When there is not enough oil in the engine oil pan, the friction between the bearing and the journal and other components will lead to poor lubrication due to the lack of oil, which will increase the wear of various parts of the engine.

However, if there is too much oil, the engine will produce violent agitation of various parts when it is working, which not only increases the loss of internal power of the engine, but also increases the amount of oil splashed on the cylinder wall, resulting in burn-out oil failure. Therefore, car owners should always pay attention to the oil warning light on the dashboard, and the oil should not be too much.

2. Too little oil.

When there is not enough oil in the engine oil pan, the friction between the bearing and the journal will be poorly lubricated due to the small amount of oil, which will aggravate the degree of wear and even cause the accident of burning the shaft.

In fact, if there is too much oil, the crankshaft handle and the big end of the connecting rod will be violently agitated when the engine is working, which not only increases the internal power loss of the engine, but also increases the oil splashed on the cylinder wall, which is easy to cause oil failure.

Therefore, the oil in the engine oil pan should be controlled between the upper and lower engraved lines of the oil dipstick.

4. Environmental protection is not up to standard.

It will worsen the exhaust emissions, seriously affect the life of the three-way catalytic converter, and may even directly damage the three-way catalytic converter.

If the edge color of the diffused oil ring is darker, the more the oil performance will be attenuated, and then the oil needs to be replaced.

Turbocharged German cars consume more oil! The trunk should have a barrel of 1 liter of oil! If you lack too much, you have to add it! Naturally aspirated engines rarely have halfway to oil! Then there is the engine problem burning oil!

Nowadays, cars have self-inspection, and there will be a display on the lack of oil meter. If it's missing, you can check it yourself and add some points. Generally, it is not usually added, and the normal wear and tear consumption (very little).

As soon as the oil lamp starts to turn on, you should add oil, otherwise running without oil will accelerate the wear and tear of the engine.

Generators require less oil.

Add oil, the generator is generally not required to be normal.

Add oil.

Check the oil for 3000km without mopping the floor.

Hello, I'm honored that your question doesn't need a dear.

There is no need to use a normal new car as long as it does not have bad fuel.

Precautions when refueling, especially when a new car1 Choose the quality of oil products directly under the regular gas station Sinopec and PetroChina, and do not refuel at a very small gas station that does not look pleasing to the eye, and at the same time be sure to keep the invoice, in case of an accident, this is the only certificate.

2 Try to choose evening and morning, because gasoline is charged by volume, not by weight, and volume will be affected by temperature, thermal expansion and contraction. When refueling in the morning or evening, the same volume of gasoline can have more mass, and it can save a lot of money after a long time of accumulation.

4 Half or two-thirds of the road across the city because the urban driving is often stop-and-go, if you fill up the fuel tank, it will be heavier the load of the engine, the start is weak and the vehicle consumes fuel, and the urban gas stations are more distributed, you don't have to worry about not finding the gas station.

The main thing is to pay attention to the first time when filling the oil, do not fill it outside the oil port cap. When the second house lives, it is necessary to determine the amount of oil according to the oil dipstick, and do not add too much.

Pacific Automobile Network] In general, it is recommended to add a bottle for 10,000 kilometers in areas with good fuel quality, and once for areas with poor fuel quality, you can add once for 5,000 kilometers. As we all know, due to the uneven level of domestic fuel quality and the poor environmental condition of the car, the vehicle is easy to produce a large amount of carbon deposition after a period of use, which is directly to increase emissions and carbon deposition.

Excessive carbon deposition will lead to poor fuel atomization, increased fuel consumption, decreased engine power, excessive exhaust emissions, and even lead to burning engine oil, pulling cylinders and damaging the engine.

In order to solve the above situation, there are fuel additives. Fuel additives are added with active ingredients and antiknock agents. The active ingredient in the additive can clean the nozzle, enter the valve and piston when gasoline is injected, so the main purpose of using fuel additives is to clean or inhibit the generation of carbon deposits in the engine and keep the engine in good working condition.

Moreover, the antiknock agent can increase the anti-knock property of gasoline, make the engine burn better and more smoothly, and improve the working condition of the engine.

Of course, the effect of using fuel additives is not immediate, and it does not mean that using a bottle can clean carbon deposits and reduce emissions. However, the study found that the long-term use of fuel additives in the engine has much less carbon deposit, and of course, the emission is also lower; Therefore, it is necessary to use gasoline additives on a regular basis, which can effectively slow down the generation of carbon deposits, reduce engine emissions, reduce fuel consumption, and ensure good operation of the engine. However, fuel treasure should also be added correctly and in a timely manner, it is best to use the original fuel additives or fuel additives produced by regular manufacturers, do not use inferior fuel additives, inferior fuel additives, may have no effect and even harm the engine.

Finally, I will tell you that the method of adding additives, additives should be added when the oil tank is almost out of oil, and then the oil is filled to make the oil and additives fully integrated. Of course, fuel additives do not need to be added to every tank of oil.
