Is it still necessary to use good lubricants for cars under 50,000?

First of all, many friends say that it is a waste to use fully synthetic motor oil for cheap cars, and the fully synthetic engine oil is too thin, and mineral oil is more viscous. In this case, the assembly process of your car is not so good, the gap is relatively large, it is better to use a viscous point, and burn the engine oil thinly. But in fact, the viscosity of engine oil only depends on the label, and it has nothing to do with whether it is a fully synthetic oil or mineral oil.

For example, the oil label is generally AW-B, and the smaller the A in front of 5W-30, the better the fluidity at low temperatures, and the <>

The higher the B in the back, the better the viscosity or lubrication effect at high temperatures. The viscosity of the oil will change with the change of temperature, the index to measure this amplitude is called the viscosity index, the higher the viscosity index, the less affected by the temperature, and the better its fluidity. The viscosity index of mineral oil is concentrated in 120 to 160, to give you a reference comparison, the viscosity index of fully synthetic is mostly above 160, which is a little higher than that of mineral oil.

Therefore, the fluidity of fully synthetic oil is very good at various temperatures, and it naturally feels thinner than mineral oil, but it actually flows more smoothly, which is a good thing. For a car of 50,000 yuan, the engine accuracy is not very good, and the viscosity of the engine oil is about the same. Let me tell you, what is the most representative car for 50,000 yuan?

Wuling Hongguang, the liter engine is the same series as Yinglang, Kaiyue L2B type. Most of the domestic brands are imitation of Japanese and German engines, although the performance may not be as good as the imitation object, but simply the difference in processing accuracy will not be too big. Because everyone uses robots from ABB in Sweden, Dürr in Germany, and Nako in Japan.

It is necessary, less than 50,000 may be the cause of the engine, so it is not necessarily other bad.

Of course, it is necessary, as long as it is a car, the engine must be lubricated to ensure the normal use of the engine.

Yes, a good lubricating oil can make the car more durable and safer on the road.

There is no need. Because a good lubricating oil car does not have this configuration to bear.

It's okay to buy a lubricant that matches the car, you don't have to buy it too well, and you don't have to buy it too badly.

Lubricating oil is necessary, if you want to use a car for a long time, the lubricant must be good.

It's not necessary, good lubricating oil has hundreds, and your car is only tens of thousands.

Of course, this is for sure, even if your car is bad, but in order to protect your engine, you still have to use good lubricating oil.

Of course, lubricating oil is suitable for all cars, so the car should try to choose a relatively low and easy lubricating oil.

I think it's still unnecessary, so let's drive it for as long as I can.

Let's be honest, I don't think there's much need for this, anyway, I don't recommend it.

You bought your cars for less than 50,000 yuan, are you still willing to buy good lubricating oil? And there's no need to buy that good, just match the car.

Of course, you can choose it, after all, the car is your own and needs to be treated well.

Any kind of car must use good lubricating oil, because this can make the life of the car more. Long.

It depends on your personal opinion, if this is your car, you can choose maintenance.

I think this is mainly up to you, and you can use it if you want to.

The fully synthetic engine oil has good stability and long replacement cycle, which can bring better protection to the engine, thereby improving the utilization rate of the car, reducing the number of maintenance times and saving maintenance costs. Overall, it's more cost-effective than using regular engine oil.

1. The so-called engine deep cleaning is actually a cleaning of the internal lubrication system and carbon deposits of the engine. Because the engine works at high temperature and high pressure for a long time, the oil sludge and carbon deposits generated will reduce the efficiency of the engine, which is very necessary for old cars of a certain age. However, most of the lubricating oil used in cars now has its own cleaning function, which can ensure that the engine does not produce sludge or a small amount within a certain number of kilometers.

Cleaning the lubrication system, air intake, combustion chamber and other items is necessary for the maintenance of the car's engine, but in the normal state of vehicle use, it will generally take 30,000-50,000 kilometers to consider.

2. Lubricating oil has the function of lubricating and reducing friction: when the engine is running, if some friction parts are not properly lubricated, dry friction will occur. Practice has proved that the heat generated by dry friction in a short period of time is enough to melt the metal, causing damage or even jamming of the parts (many cars with water or oil leakage have failures such as pulling cylinders and holding axles, which is the main reason).

Therefore, the friction parts in the engine must be well lubricated. When the lubricating oil flows to the friction part, it will adhere to the friction surface to form a layer of oil film, reducing the resistance between the friction parts, and the strength and toughness of the oil film are the key to its lubrication effect. However, the amount should not be too large, because when the amount is too large, the resistance of the square relationship will be generated, which will have a great impact on the speed, so special attention should be paid to the dosage.

3. Lubricating oil has the function of cleaning: when the engine is working, a lot of dirt will be generated. For example, the sand and dust brought by inhaling the air, the carbon deposits formed after the combustion of the mixed gas, the gelatinous matter generated after the oxidation of the lubricating oil, and the metal chips generated by friction between the parts.

These dirt will adhere to the friction surface of the machine, and if it is not cleaned, it will increase the wear of the machine. In addition, a large amount of gum can cause the piston ring to stick and get stuck and cause the engine to not function properly. Therefore, these dirt must be cleaned in time, and this cleaning process is completed by the circulation of lubricating oil in the body.

4. The use of high-quality lubricating oil can better protect your car, so it is very important to buy the best engine oil, you can go to the monopoly ** engine oil ** of Yutu Network to see, I hope it can help you!

Personally, I suggest that it is best to maintain the car according to the maintenance manual, and it is more appropriate to maintain the car, which can be referred to.

The mileage of private cars exceeds 50,000, remember that these 3 accessories are only replaced and not repaired, and it will be too late when something happens.

Vehicles are on track.

Drive 5w kilometers and recommend the maintenance of the project system

It is recommended to change the oil and filter. Hair.

Motor air filter, air conditioning air filter, gasoline filter, spark plug, brake fluid. Clean the lower throttle and carbon deposits.

Detect the degree of wear of tires and brake pads, detect whether the engine belt is open, check whether the rubber parts of the chassis are aged and cracked, and detect whether the brake oil, transmission oil and antifreeze are deteriorated.

For specific maintenance items, you can check the maintenance manual of the vehicle, which will specify how many kilometers and how many years to replace and what maintenance to do.

Do a full inspection, tighten the tires, focus on the braking system, usually if everything is normal with the vehicle, there is nothing to worry about, check in place.

Car maintenance is determined according to the actual service life of each part, and the routine regular replacement of organic oil, oil filter, air filter, fuel filter, air conditioning filter, carbon canister, transmission oil, brake oil, booster oil, antifreeze, transmission belt, etc. There are also regular inspection and adjustment and replacement items, such as four-wheel alignment and transposition, brake pads, tires, etc.

When the vehicle is purchased, the owner's manual and maintenance manual with the car will make a basic introduction to the consumables of the vehicle, and the replacement and maintenance cycle will be recommended around these consumables, it is worth noting that this cycle is not absolutely fixed, it is different according to the current vehicle condition, driving road conditions, basic use, etc. For example, the first warranty of a new car is generally earlier than the subsequent warranty, and the tire replacement of bad road conditions is in advance. Reasonable maintenance measures can effectively reduce vehicle wear and tear and ensure the performance and life of the whole vehicle.

Now there are cars of various classes. People also change cars more frequently, and they always think that a good car will be safer. In fact, no matter how much a car costs, the main factor affecting the health of the vehicle is maintenance.

Especially when the car runs 50,000 kilometers, these three parts must be checked and replaced, and if they are not replaced, it is equivalent to "destroying the car"!

The project maintenance that needs to be done for the car to travel 50,000 kilometers:

Change the oil and filters.

Check to replace the brake pads.

Check to replace the spark plugs.

Clean the throttle and injector.

Wash and clean the water tank.

Change the brake fluid.

Look at the tires and pay attention to changing them.

The role of the car to do various maintenance after 50,000 kilometers:

The oil and filter element should be changed once every 5,000 kilometers under normal conditions, and the oil should be changed once every 3,000 kilometers if the dust is large. Engine oil, that is, engine lubricating oil, is known as the "blood" of the car, which can lubricate, clean, cool, seal, reduce wear, prevent rust and corrosion of the engine.

The life of the brake pads of the vehicle is about 4-5 years or 40,000 kilometers, of course, according to the driving habits, driving environment, and speed, the degree of wear is also different. Generally, vehicles that often run at high speeds, the brake pads wear very little, often drive in the city, and the brake pads that are often jammed are badly worn. We can see the thickness of the brake pads ourselves.

Note that the rear is a drum brake, and it takes longer to replace.

A good spark plug can generally be used for 2-3 years or 2-30,000 kilometers, but if the vehicle is running with insufficient power or acceleration shake, it means that there may be a problem with the spark plug, and it should be checked as soon as possible.

Throttle and fuel injector driving for a long time, easy to enter dirty things or carbon deposits, need to be cleaned regularly, the general vehicle runs more than 50,000 kilometers to check and clean, but according to their own driving environment to determine the frequency of cleaning, when the environment is very dirty, it is necessary to shorten the cleaning time.

When the vehicle travels more than 40,000 or 50,000 kilometers, the water tank often hides dirt and dirt, which is very dirty, which affects the refrigeration and cleaning of the engine, so if the inspection is really dirty, the water tank should be washed. Here it is recommended not to listen to the foolishness of the repair shop, and ask a few more, the water tank does not need to be cleaned if it is not dirty.

In addition to the brake pads, the brake fluid should also be changed regularly, either along with the brake pads or according to the kilometers driven. The brake fluid should be selected, after all, the vehicle's braking system is the most critical.

The general life of the tires of the vehicle is four or five years, even if the mileage is very small, because the tires are often exposed to the sun, the aging phenomenon is also very common, so when the side cracks of the tires are very large, or the tread pattern reaches the minimum limit, it is necessary to check whether it is to be replaced.

The car will wear out after driving for a long time, and maintenance can reduce aging.

For 40,000 kilometers of cars, conventional maintenance (oil filter) still has to be done, and then replace the air filter, air conditioning filter, gasoline filter, and replace the three filters.

The most important thing to maintain in car maintenance is to change the oil and oil filter, and there are some small maintenances, in the summer, whether the wipers are replaced, tires, wheel alignment, circuits, etc., some items are free.

Because the car will have a certain amount of wear and tear after driving for a long time, it needs to be maintained.

Because after the car is used for a long time, the loss of parts is relatively large.

After a long drive, the parts of the car will wear out a little.

After a long period of driving, both the body and the interior of the car are worn.

If you have a car, you need to maintain it, check the air filter, air conditioning filter, and gasoline filter, and replace it if there is a problem.

After driving for a long time, the wear and tear of the internal parts of the car is more serious.

If the wear is serious, it needs to be maintained, otherwise it will be dangerous.

Check if there is a problem with the part and eliminate hidden dangers.

1. Change the oil and oil filter. This is a must do for every maintenance, under normal circumstances, the oil replacement cycle should be considered according to the type of oil, if you are mineral oil, then you need to consider changing the oil after 5000 kilometers, if it is a semi-synthetic oil, it can be used for a longer time, 7500 kilometers when you change the oil.

If it's fully synthetic, it's even better, just change the engine oil after 10,000 kilometers, and everyone can change the engine oil according to this time range. The oil filter is used to filter impurities, so the oil filter should be replaced when the oil is changed.

Two: spark plugs. The function of the spark plug is to ignite the combustible gas mixture in the cylinder, once the working time is too long, it will make the engine run unevenly and produce shaking, and even form a lack of cylinder, which can not ignite, and at the same time will make the engine more fuel-efficient, so the role of the spark plug is very important.

The replacement cycle of iridium spark plug is 80,000-100,000 km, the replacement cycle of platinum spark plug is 50,000-60,000 km, and the replacement cycle of nickel-gold spark plug is 20,000-30,000 km.

Three: tires and batteries. Tires and batteries are consumables, at 50,000 kilometers are generally the replacement point of tires, maintenance should pay attention to check the wear of tires and the life of the battery, if there is a problem to replace in time.

Four: timing belt. It is an integral part of the engine, and its role is to ensure the accuracy of the intake and exhaust times through the connection with the crankshaft and a certain transmission ratio. It is a consumable product, and it will be replaced in time when the cracking is detected during the 50,000 km maintenance.
