Question 2: What brand of engine oil is better for car maintenance? No matter what brand of car, there will always be wear and tear in the process of use. Just like the tires of a car running on the road for a long time, the rubber will become thinner and thinner, and other parts of the car will "die" because of frequent use. Cars are at the peak in the first two years, and there is basically no problem, but cars that are more than two years old will start to replace some parts.
Teenagers: cars of 2-5 years old.
When a car is sent for maintenance, it is necessary to check its brake pads first, because this is the first line of defense for driving safety. According to experience, brake pads will wear out in about 2 years. Usually, cars that are 2 or 3 years old need to be replaced with new brake pads.
The exact service life depends on the driver's habits. If you are the kind of person who likes to step on a lot of oil and then slam on the brakes at a critical moment, the wear of the brake pads will definitely be severe and the service life will be short.
At this time of the car, the fuel injection pump should be cleaned or replaced.
After driving for three or four years, you may find that it is not as smooth as a new car. In this case, it is time to check the shock absorber of the car.
As the name implies, the function of shock absorber is to reduce the vibration of the car. It is a part of the suspension system. If the spring of the shock absorber is no longer elastic, it will shake badly when driving at high speed, especially in rainy days.
If the car is about 4 years old, pay attention to whether the timing belt should be changed. Generally, when a car travels 700 to 65438+ 10,000 kilometers, it should be sent to change the timing belt. If it is not replaced in time, the car suddenly breaks down halfway, and the maintenance cost is at least several hundred yuan.
Middle-aged: 4-7 years old car.
Many people like to change a car every four to five years, and many used car buyers like to buy cars of this age. Although this old car is good, the problems under the hood appear.
What's the main problem?
At this time, the car is like "middle age", and many things are loose, including all kinds of rubber pipes in the car.
If the cars in this era are not well maintained, some problems of black oil leakage will come out. This is natural. When rubber pipes are used, there is always a problem of hardening. If the owner maintains it well, the problem of hardening will appear later, otherwise the trouble will begin.
In addition, the water tank of the car has been used for so long, about 5 years, and it may be corroded by chemicals inside. Some cars' water tanks began to leak, so they should be replaced.
7- 10 automobile
At this time, those things that were changed in the third year and the fourth year should be changed almost again, such as shock absorbers. In addition, most automatic cars need to repair the automatic gearbox at this time.
When driving an automatic transmission car, you should also shift to a low gear at the right time, so that you can use different gears alternately and prolong the service life of the automatic gearbox.
Because of the service life of automobile license plates, cars in China are generally killed in 10 years. If properly maintained, every car should be able to complete the task.
Replace black oil, filter, etc. Checking the car regularly and spending a little money regularly can save a lot of money and make it safer to drive.
Common sense of new car maintenance
1. Try to use good engine oil.
Try to use engine oil with higher API grade, such as SL, SJ or CI-4, CH-4, etc. Good engine oil can not only prolong the service life of the engine, but also save fuel. Especially for engines equipped with hydraulic system (such as VVT-I) and turbocharger, it is necessary to use high-performance engine oil, which is not only difficult to oxidize at high temperature, but also will not leave deposits in the precise parts of the engine, greatly prolonging the engine life. It is recommended to use all synthetic engine oils.
Don't forget to change the belt.
High-performance engines mostly use overhead camshafts, and camshafts are mostly driven by belts. The life of these belts is mostly 60,000-80,000 kilometers. If this belt breaks, the whole valve distribution system will be chaotic, and the upward movement of the piston may interrupt the valve and the engine will be smashed into a ball.
3, automatic transmission oil change must be operated by professionals.
Automatic transmission oil change is complicated and must be operated by professionals. The automatic transmission can only prevent and remove oil less than 1/3 by only putting the oil pan, so it must use ... >>.
Question 3: Which brand of automobile oil is good? Not bad in every way. You can try Hermes oil.
Question 4: If you want to use the best brand of automobile oil, I will say the more powerful brands, such as Mott, Fast Horse, Anceaux, Red Line, etc. These are all expensive, but the performance of the oil can't be said. Base oils are all in five grades, which are suitable for some turbocharging heads or performance models.
Medium-sized brands, such as Mobil, Shell, Castrol and Total, have relatively moderate prices.
The viscosity of engine oil depends not only on the season and brand, but also on the viscosity of engine oil. Most of the engine oils recommended by the original factory are based on that viscosity.
For example, like many European cars (like Volkswagen brands), especially cars with turbocharged engines, the viscosity requirements are relatively high, generally in the range of 30-40.
Like many Japanese and Korean cars (such as Toyota and Hyundai), the viscosity requirements are relatively low, generally in the range of 20-30 (mostly 20).
Question 5: What brand of engine oil is good? If you want to be cheap, Mobil Castrol Shell is very good. Pay attention to whether there is API certification on the bottle ~SN is the highest quality engine oil in the world today. Take 15W-40 and 5W-40 as examples.
5W refers to the lowest adaptive temperature (-30), and the following 30 and 40 refer to the adaptive ambient temperature. Specifically, the viscosity of lubricating oil is marked by SAE grade, which is the abbreviation of American Society of Automotive Engineers. For example: SAE 15W-40, SAE5W-40, and "w" means winter (winter). The smaller the number before it means the better the low-temperature fluidity of engine oil, which means the lower the available ambient temperature, the better the engine protection ability during cold start. The number after "W" (with a horizontal one behind it) is the index of high temperature resistance of engine oil. The larger the number, the better the protective performance of oil at high temperature.
(SAE) Applicable ambient temperature (℃)
5w External Low Temperature Resistance-30 C
10w external low temperature resistance-25 c
15w external low temperature resistance-20 c
20w external low temperature resistor-15 c.
30 external high temperature resistance 30°C
40 external high temperature resistance 40°C
50 external high temperature resistance 50°C

Flowserve Lubricant: Flowserve Petroleum Group, founded in 193 1, is the largest lubricant manufacturer in the world. Total lubricants: world brands, French brands and top ten engine oil brands 9. BP lubricating oil: a famous trademark in Zhejiang Province.
Question 7: Which brand of engine oil has the best five functions of lubrication, cooling, sealing, cleaning and rust prevention?
From the perspective of cost performance, semi-synthetic engine oil is the most suitable choice. SAE SM grade label 10W or 5W, price 250-300 yuan. It can really save fuel, extend the maintenance period to 10 thousand kilometers, and better protect the engine
As far as the engine oil we can easily buy is concerned, ABRO car oil is also a very good engine oil, and the market price is not expensive, so the public demand is feasible. I suggest trying some. I just read it online, and it seems that Dongguan Lei Ying Lubrication Technology Co., Ltd. is the general agent of China.
Question 8: Which brand of Shell series is better in synthetic engine oil?
Shell Extraordinary Heineken is 15W-50 50 all over synthetic engine oil, which is different from the semi-synthetic products of general Heineken. It conforms to SJ grade established by American API, and Europe A3-96: B3-96. JASO SG class. It mainly provides better protection for multi-valve engines and high-performance cars, and plays a special role in the smooth operation and cleaning of engines. It is also the designated oil for Ferrari Formula One team and its production cars.
Mobil Mobil series
Mobil 1 (Mobil 1) is a fully synthetic oil that Mobil Oil Company has spent 20 years researching, belonging to 5W-50 composite viscosity API SJ/CF, ACEAB3-96 and A3-96. In order to solve the problem that general engine oil has insufficient anti-wear ability and unstable performance to temperature (high temperature and low temperature).
In one experiment, a brand-new BMW 325i and this miscellaneous brand machine * * * walked more than 300,000 kilometers, and then the engine was disassembled to evaluate the cooperation loss. Compared with similar engines, it only travels 1500 km, and the result is that there is no obvious difference between them.
Haveling equation series
Caltex's "golden wealth" equation is listed as API SJ in synthetic engine oil (SAE5W-40). SH and European version CCMPD 2? G5 grade is developed by combining synthetic lubricating oil and additives with artificial chemistry. This kind of oil is suitable for all types of gasoline engines, which is characterized by strong oxidation resistance, reducing the formation of deposits and fuel consumption, and has remarkable efficiency even when it is started at a low temperature of -50 degrees. Because of its extremely low wear resistance, it can keep its viscosity unchanged even under long-term high load. It has become the engine oil selected by many racing teams, and the service life of ordinary cars can be extended. At present, large German automakers such as Mercedes-Benz, BMW and Porsche will use this oil in their vehicles.
The semi-synthetic engine oil SAE 15W-40 40, (API SJ, CCMC G4) is a high-tech engine oil specially designed for gasoline engines, which can reduce the engine starting resistance and prevent the oil from deteriorating at high temperature. Its characteristic is that it can ensure that the viscosity of engine oil is not affected by temperature change and maintain its original wear resistance.
Caltex
Caltex "Dele" 500 Mulltigrade multi-grade engine oil, SAE 15W-40 API SG/CF4 grade, suitable for turbocharged or heavy-duty gasoline and diesel engines, generally used for passenger cars and large trucks; It also has the functions of cleaning, anti-oxidation and prolonging engine life.
CXT duobao engine oil
CXT engine oil, (SAE 15-40) API SG/CC and CCMC G4 specifications, is especially suitable for high-temperature and efficient gasoline and diesel engines. Turbocharged cars can also be taken care of, which can reduce sludge, reduce the wear and tear of bearings and parts, and reduce maintenance costs.
Bp BP series
BP (British Petroleum Company) is a product that only entered the China market in recent years. In fact, BP is the largest international petrochemical company in the world, and its main engine oil series is VISCO microcrystals used in general automobiles. Including the first 5000,3000,2000 oils.
VISCO contains a microcrystalline molecular technology lubricating oil called HC-4, which can effectively enhance the adhesion on the surface of engine metal parts, thus providing protection for the engine.
VISCO 5000 SAE 5W40, belonging to API SJ/CF, ACEA A3-96 and B3-96, is suitable for high-performance turbocharged gasoline and diesel engines, effectively reducing friction, keeping the engine clean and saving fuel.
VISCO 3000 SAE 15W50 is semi-synthetic engine oil, with API grades of SJ/CF, ACEA A2-96 and B2-96, and its wear resistance is worse than 5000, so it is suitable for diesel and gasoline engines.
As for VISCO 2000 SAE 20W50, it is especially suitable for ordinary car owners. In addition to being cheap, there are also basic requirements for protecting the engine and saving fuel. The API is SJ/CF and ACEA is A2-B2-96, which is especially suitable for the displacement of 2000 ml. > & gt
