Will oil additives be added to the car secondary maintenance project?

Oil additives are optional items and do not add depending on the individual. However, the engine oil itself has an additive formula, plus other additives, if the proportion is not well controlled, it may affect the lubrication effect of the oil, affect the driving experience, it is not as convenient as directly changing to high-quality fully synthetic engine oil. So my second insurance is to directly change the GT oil, the car is not like the original engine oil before the start of the meat acceleration slow, the overall performance has been greatly improved.

As for the original engine oil, it can't even run 5,000 kilometers because the original factory is a mineral semi-synthetic engine oil of average quality, and 5,000 kilometers is the maximum mileage that can be run, and the power will begin to decline from two or three thousand kilometers. If you usually have a lot of traffic jams, you need to replace the emergency car in advance.

The car needs to be well maintained for the second time, pay attention to the following items: change the oil, oil grid, gasoline grid. Check that the tire pressure is normal.

Check that the cantilever and shock absorption are fixed and fixed reliably, the function is normal, and the temperature of the hub bearing is not high after driving. After checking that the engine has passed the three cleaning and three filtration operations, it should be easy to start, run smoothly, exhaust normally, water temperature and oil pressure meet the requirements, the speed is stable, there is no abnormal noise, the belt tension is moderate, and there is no water leakage, oil, electricity and gas. Check that the direction of free travel and toe meet the requirements, the steering is light, flexible and reliable, and there is no left and right swing head and deviation of the front wheels when driving.

Check that the free stroke of the clutch meets the requirements, the operation is convenient, the separation is thorough, the combination is stable and reliable, there is no abnormal noise, and there is no oil leakage in the hydraulic system. Check that the gearbox, drive axle, or half-shaft transmission device is well lubricated, the connection is reliable, there is no abnormal noise and overheating, no jumping, flexible shifting, and no oil leakage. Check that the free stroke of the brake pedal and the brake intermittently meet the requirements, the driving and parking brakes are good, there is no deviation and lag during braking, and the inertia proportional valve works normally and does not leak oil.

Check that the generator, starter, lights, instruments, signal lights, buttons, switches and accessories are fully equipped and complete, and can work normally. Each lubrication point of the whole vehicle is filled with lubricating oil. Air grid, air conditioning grid, brake fluid, booster oil, antifreeze, etc.

First of all, we need to know what fuel additives are? It is to make up for the defects of some properties of fuel and give fuel some new excellent characteristics, functional substances to be added to fuel. The main functions are to improve combustion efficiency, save gasoline and reduce exhaust emissions; Clean the sediment of the fuel injector to keep the oil circuit smooth and ensure the normal output of engine power; Remove the carbon deposits in the inlet valve and eliminate the faults such as the drop in cylinder working pressure, incomplete combustion and detonation; It can also keep the engine clean and in the best working condition for a long time, reduce car maintenance costs, prolong the service life of the engine, and reduce the pollution of exhaust emissions to the environment.

As long as it is a car, then it definitely needs fuel additives. If you are buying an imported car, then fuel additives are even more needed. Because imported engines will be due to the quality of oil products, there will be some water and soil adaptation.

This is mainly caused by the fuel substandard, and the maintenance of the vehicle fuel system should be at any time, many vehicles will appear with the operation of the idle unstable, poor acceleration, the car is not energetic, and the fuel consumption, the air conditioning load shivering and other problems. And if your engine deposits carbon.

Too much is also related to the unclean combustion system, and if this happens to your car, then you need to use fuel additives to clean it.

But many car owners do not know how to add, the first proportion of adding is generally 1 1000, 1 bottle of 50ml additive can be equipped with 50 liters of fuel. In addition, we also have to depend on the condition of the car, the model, the first time the vehicle in good condition is used about 3 bottles in a row; Vehicles with declining vehicle condition and insufficient power need to use more than 5 bottles continuously until the vehicle condition improves, and then choose to add it once in the box or every 1000 kilometers. If you find that your car is performing a lot worse than before and there are constant minor problems, then you can use fuel additives.

When maintaining the 4S shop, whether to add fuel additives depends on the situation. If you feel that everything is normal in the vehicle, there is no need to add, if you feel that the vehicle has abnormal phenomena such as lack of acceleration and unstable idling, it is recommended to go to the 4S shop to use fuel additives under the guidance of professional engineers.

Many vehicles mainly drive in urban areas at low speeds, which can easily generate carbon deposits and clog fuel injectors. Fuel additives can improve engine combustion efficiency, combustion temperature, increase engine cylinder pressure and improve engine power. In addition, fuel additives also improve atomization and save fuel; Anti-corrosion, anti-rust, lubrication, protect the engine; Reduce noise, reduce wear and tear, and extend engine life; Eliminate black smoke, reduce emissions, etc.

Yes, when the second maintenance is done, the car has basically reached more than 1,000 billion kilometers of travel, and adding engine cleaners can reduce carbon deposits and ensure the normal operation of the vehicle and safe driving technology.

It is necessary. After the new car is running-in, especially after it is on the road, it must be cleaned well to remove the dust and impurities inside.

OK. Because adding engine cleaner and protective agent can better protect the car, it can be added.

The car is maintained for the second time, and the 4S shop recommends that I add engine cleaner and protective agent, do I need to do it?

Engine cleaners and protective agents are simply understood as car health care products, we might as well think about who is the main consumer group of health care products that we humans eat? That's right! The main consumer group of those health care products on TV is the elderly!

Advanced maintenance items: see the yellow item, this car is done within 30,000 kilometers, which is equivalent to early maintenance, and about 1,200 yuan was consumed in advance! This is also one of my wishes.

The oil tank and rubber tubing are corroded.

If the 4S shop asks you to add engine washers, agents and protective agents, you can directly ask the 4S shop whether it is the quality of the car or the quality of the original car oil? No matter how many times your private car is serviced, as long as the oil used is a qualified product that meets the manufacturer's oil standards, and the oil is changed according to the maintenance interval in the manufacturer's maintenance manual, unless your driving style is too intense, there is no need to use engine cleaners and protective agents.

Engine cleaners and protective agents are simply understood as car health care products, we might as well think about who is the main consumer group of health care products that we humans eat? That's right! The main consumer group of those health care products on TV is the elderly!

Advanced maintenance items: see the yellow item, this car is done within 30,000 kilometers, which is equivalent to early maintenance, and about 1,200 yuan was consumed in advance! This is also one of my wishes.

The oil tank and rubber tubing are corroded.

Therefore, if you look at the car as a person, the vehicle of the second insurance, the stage when the comprehensive performance of the vehicle has just begun to improve, belongs to the youth stage of human beings, so let such a young vehicle eat health care products? So is it possible to understand that when the car is driving at medium speed, it injects fuel 1250 times per minute? According to this calculation, the result should be 480 milliseconds per intake stroke; This speed is basically the same as high-frequency deliberate blinking.

What solvent and fuel mixture dissolves carbon instantaneously at high frequency? If possible, the solvent will corrode the plastic tank and rubber pipe.

During maintenance, the driving environment is better, the average speed is higher, and the driving habits are gentle, then the maintenance time and mileage can be appropriately extended; On the other hand, if the road is congested and you often drive violently, then reduce the maintenance time and mileage appropriately.

Use a less viscous oil to keep the oil path clear. 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.

The following brands are available, Shell, Castrol, Mobil.

1.Engine oil, that is, engine lubricating oil, can lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the "blood" of automobiles.

2.Engine oil is composed of two parts: base oil and additives. 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.

3.The 5W W-30 in the engine oil indicates the viscosity grade of the engine oil, and the stool cherry is the SAE grade. "W" means winter.

The smaller the number in front of w, the smaller the low temperature viscosity calendar, the better the low temperature fluidity, and the lower the applicable minimum temperature. The number after w does refer to the viscosity of the oil at 100 degrees Celsius, and the higher the number, the more viscous the oil. The following figures mainly refer to the index of the high temperature resistance of the oil, and the better the protection performance at high temperatures.

4.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

5.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

6.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to 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.

The car is maintained for the second time, and the 4S shop recommends that I add engine cleaner and protectant, is it necessary?

In the 4S shop, only this product name includes"agent"Words, are some accessories, there is no absolute benefit to the vehicle, and there is no harm, but these things are often the most profitable. Sometimes, when you take advantage of the opportunity to maintain your car, you will be sold by salespeople. So how do we make a judgment?

Engine cleaner.

Engine cleaner is the function of cleaning up carbon deposits inside the engine, including the greasy adsorption of the cylinder block. In fact, the engine oil itself has the effect of cleaning carbon deposits and greasy, and if you add detergent to increase the measurement, it will have an effect to a certain extent. However, there are many disadvantages due to improper use, due to the addition of chemicals, it will break the proportion of engine oil content, and there is serious corrosion to sealing rubber products.

If you add new oil and cleaning agent at the same time, it will definitely not work for a long time. There is only one way to use it, that is, when changing the oil, add it to run for about 10 minutes, and then drain the oil to replace it with new oil.

Engine protectants.

Engine protectant is actually anti-wear agent, and the main content of anti-wear agent is:"Zinc"Zinc is a polar molecule that is easily attracted to the surface of steel. Under heat and load, zinc reacts with the steel surface and forms a phosphate glass film that protects the steel surface by forming a layer that covers and fills in the convex and concave of the steel surface. Protective agents are generally used in vehicles with relatively high kilometers of transportation, and the engine can play a certain role in protecting the engine from wear.

However, it is not recommended to use it in new cars, and it is also a chemical product, which will also break the balance of the proportion of engine oil components. If the number of kilometers of the car, when the power performance has decreased, it can be used appropriately, anti-wear agents are now very popular in the market, and many cars are using them.

The best way to protect your engine.

If an engine wants to be used for a long time, it only needs to change the oil, filter, and air cleaner on time, start with a small throttle, and don't let the vehicle run under load.

Summary: Before maintaining the car, you can carefully check the vehicle manual, if it is not prescribed by the car manufacturer, it is recommended not to try it lightly.

I don't think it's necessary. Because adding these two things doesn't do anything for the engine, there's no need for anything.

When the vehicle is undergoing the second maintenance, the 4S shop recommends adding anti-engine cleaning agent and protective agent, which I think is very unnecessary, and generally does not need to add these things if you do not drive a long number of kilometers.

The car was maintained for the second time, and the 4S shop suggested that I add engine cleaner and protectant. I don't think it's necessary if you love the car when you drive.

When we do engine maintenance, we often change the engine oil, and sometimes we will add maintenance agents for maintenance, but in general, it is not recommended to use, because the technology of the computer is very mature, and there is no need for these additional means of maintenance.

There is no need to add engine protector, because this protective agent has a very small maintenance effect on the engine, and it cannot play a maintenance role in the engine, but has a feeling of spending money in vain.

It is not necessary to buy a new car, as long as the oil is changed regularly, after all, the additives in the oil will also meet the needs of the engine.
