What is the quality of the lubricating oil in the daily refining of the worker, and the large excava

I have used this, my 350 excavator is used in this, the oil is still very good, it seems to be a brand in Japan, just entered the country.

The quality of the lubricating oil is not bad, so you can use it.

Damage to the engine seal surface and oil seal will cause leakage of lubricating oil. Once a leak occurs, it can be observed outside the engine. Such as:

When blue smoke comes out of the exhaust pipe, the lubricating oil enters the combustion chamber and is burned. Lubricating oil can enter the combustion chamber in three ways. (1) Wear occurs between the duct and the valve stem, and the gap is too large, and the lubricating oil droplets in the valve cover will enter the combustion chamber along the gap when the air is intake; In the event of this failure or enlargement of the valve guide aperture, the intake valve with a larger valve stem should be selected.

2) The valve smoke ring fails, and the oil cannot be effectively organized to enter the combustion chamber through the valve. (3) The piston ring and cylinder wall are worn too much, and the oil scraping effect of the oil ring is weakened, so that the oil enters the combustion chamber. (4) The crankcase ventilation valve is bonded and cannot be moved, and the effect of controlling the ventilation volume is lost, and the excessive lubricating oil vapor in the crankcase enters the intake pipe through the crankcase ventilation pipe.

In addition to burning engine oil, there may also be the following reasons: (1) Engine oil leakage, especially the crankshaft. (2) Too much oil was added and (3) Shoddy oil filters were used. -

I used the Hitachi 350 before, and it was ok.

Automobile lubricating oil is not the same as excavator lubricating oil, and excavator lubricating oil generally uses Shandong Wanyou L-HM high-pressure anti-wear hydraulic oil.

Product Features: Excellent extreme pressure and anti-wear performance, slow down the wear of equipment, and effectively prolong the operating life of the pump and system; Excellent thermal stability and oxidation stability, slow down the decay rate of oil products, and prolong the oil change period; Excellent foaming resistance and air release properties ensure that the system transmits static pressure energy sensitively, accurately and smoothly; Excellent demulsibility and filtration can quickly separate the water mixed into the oil, minimize the filter blockage, and ensure the normal lubrication of the oil; It has good applicability with various conventional sealing materials.

Theoretically, it can be used with the lubricating oil of some diesel cars, but the working intensity of the excavator is high, and the working environment is more severe than that of the car, so different lubricating oil should be used.

It's basically the same, because the excavator lubricating oil doesn't have very high requirements for engine oil, but the requirements for hydraulic oil are very high.

Automobile lubricants include gasoline lubricating oil and diesel lubricating oil, and excavators are all diesel, theoretically and some diesel car lubricants can be universal, but the working intensity of excavators is large, and the working environment is more severe than that of cars, so it is best to choose professional lubricating oils, such as Mobil Delvac.

How do you say this, it depends on what car you have. If the car is a BMW or Mercedes, the engine oil used must be good, and if it is bread, just find some engine oil. If the excavator is a new imported car, it will definitely use good engine oil, generally around 800.

Diesel machines are the same, but according to the working conditions can choose different grades and viscosity, general excavators to use CF-4 or above grade oil.

Sinotruk engine lubricating oil and excavator engine lubricating oil are the same, and the hydraulic oil used for excavators is very good

Not the same.

From the engine oil alone, one is for gasoline engines and the other is for diesel engines.

In addition, the excavator seems to need some hydraulic oil.

The model is the same!

It's all the same, if you take a closer look, it may be from a manufacturer.

Excavators generally do not have special oils.

What kind of engine oil is used has no necessary relationship with EFI direct injection. The difference lies in the different oils used for gasoline engines and diesel engines. The excavator uses a diesel engine, so diesel engine oil should be used.

The performance of diesel engine oil itself is graded (API American Petroleum Institute), CA, CB, CD, CE, CF, CF-4, CG-4, CH-4, CI-4, CJ-4, and the higher the grade.

The CA level is the lowest, the general truck uses CF or above, the excavator uses the same, and most of the products sold on the market are CF grade.

However, it should be noted that the CF grade can be said to be the lowest level that can be used by the excavator engine, and the engine oil specified by the manufacturer is usually above the CF, CG, CH, etc., after all, the excavator is not as good as the truck and tractor. The higher the grade, the higher the performance, and the higher the price, which is probably the reason why the excavator designated oil is expensive.

For all oils, there is another indicator, which is the viscosity index (SAE American Society of Automotive Engineers), 20W, 15W, 5W, and the viscosity increases the further you go. Usually excavators use multi-grade viscosity oil. This is related to the climate temperature, the general area is used SAE15W-40, and in extremely cold weather, a thinner point is chosen.

Yes, excavator special engine oil is to fool customers!! There is no such thing as a dedicated one!!

If your excavator is not powerful enough, boring, emitting black smoke, consuming diesel fuel, and burning engine oil, use super beautiful eutectic lubricating oil to ensure that it does not burn engine oil, and the power is leveraged. I am from the factory, and I can approve it directly.

Special engine oil is a lie, excavator engines are generally imported, as long as you use big brands, there is no problem, such as Meifu, Shell, Total can be recommended to choose the CI grade, it is definitely no problem.

It is recommended to use Mobil, Shell, Great Wall will also be used, it is best to choose CJ-4, the money is not much hundreds of dollars, the so-called special is just for the merchant to let you only buy their oil, their so-called special engine oil is also OEM sales, not good not on the market quality, high level hope can help you.

Yes, it's all from the manufacturer. But you can also use a better oil.

First of all, the excavator is parked in a relatively flat place, and it is best to stop it overnight, and then start to change the oil the next morning, but do not use the engine, these two points have the advantage of being able to put the waste oil more thoroughly.

Oil change is to remove the screws of the engine oil pan, catch it with a barrel below (waste oil can be sold for money), you can disassemble the oil filter at the same time as the oil, the general oil filter can be installed after dismantling, there is no need to wait, just use a paper towel to touch the waste oil on it to install it. When installing, you don't have to use too much force, so as not to crack tightly, generally after the new filter is installed, the engine will be used for a day, and the filter will be tighter after high temperature. After seeing that there are no waste oil dripping in the oil drain hole below, you can add new oil, and you can also add a little before adding to remove the remaining waste oil from the oil pan (almost all engines are difficult to drain all the waste oil at once).

However, it is also possible to add fresh oil directly.

When adding new oil, you must check the oil ruler while adding, so as not to add too much oil, when you see that the oil has reached the upper end of the oil ruler mark, you can generally start the engine, remember not to increase the gas pedal, let it turn low for a minute, and then turn off, after 30 seconds, to check the oil, this time the oil will generally be a little less than the original, because part of the oil is in the new oil filter, you must add a little until the oil reaches the upper end of the oil ruler mark. After changing the oil, remember to check if there is any oil leakage in the area you just removed. It is best to clean the engine with some water, and it is best to keep the water away from the generator and motor to avoid short circuit.

You can ask the repairman to help you, the oil is not anti-wear; Worn out;

Excavator burns oil? Audi cars burn engine oil? The oil is no longer wear-resistant; I've got the BMW right;

Do know the task:, thank you!!

No matter what kind of oil, as long as the anti-wear property is good;

After many BMW cars that burn engine oil use super eutectic lubricating oil, they are pleasantly surprised to find that they no longer burn engine oil, because it is nano anti-wear repair engine oil; At the same time, the oil of large trucks and trucks is also particularly powerful; Directly approved by the manufacturer;

The wear resistance of the engine oil is not good, and it can be improved a lot by using the super eutectic lubricating oil with good wear resistance;

The general fuel additive is a bottle of 50 ml with 60 liters of gasoline, first fill up the fuel, and then pour it in;

However, I recommend you to use Chaomei brand fuel additives for Sinopec OEM;

The real way is to buy an engine internal cleaning agent produced by Chaomei, pour it into the oil cylinder, idle for ten minutes, and then replace it...

You use poor engine oil, which is not resistant to wear and tear, and soon burns the engine oil, tens of thousands of kilometers; With engine oil with good wear resistance, it is basically difficult to wear, and it will not burn engine oil for life;

Do you still believe in the original? The original one is the most basic qualified; Definitely not the best;

These oils are average, and no one is better than the other; You need to use a good anti-wear oil to protect the car;

Burning engine oil means that the engine oil is not anti-wear, and the wear particles are too large, resulting in poor sealing before burning engine oil;

Use super eutectic lubricating oil with good anti-wear performance to repair the slight burning of engine oil; And it's not expensive;

It is not normal to burn engine oil, either there is a problem with the assembly, or the engine oil is not wear-resistant;

The engine oil used is not good and does not play a role in anti-wear; Wear and carbon deposits are generated, resulting in louder noise;

Remove carbon deposits, enhance power, eliminate exhaust gases, save fuel and reduce fuel consumption.

Use super eutectic lubricating oil, close to zero wear, no oil burning;

The engine oil has a plastic cover on the engine, just unscrew it and add it, and the hydraulic oil has a single oil tank

In fact, this is due to the characteristics of the excavator when working, these working parts of the excavator are "low-speed and heavy-load", and the sealing is not good, if the use of liquid lubricating oil is easy to leak during work and can not form a good oil film. Therefore, grease needs to be filled at the axle pin of the front end of the excavator working device, which has a long retention time, and can stick to each lubrication part to form an oil film to maintain good lubrication.

The benefits of butter diligent beating are really great for the excavator, the pin and shaft sleeve wear will be much slower, and the working gap in these parts will be smaller. The noise and accuracy of the excavator will also be much better when working.

No problem. Many machines can be used, as long as you don't dislike using it for a long time, it is more dirty to absorb ash.

Great Wall Lubricants They have a series of engine oils Zunlong, and there is absolutely no problem with this. The Great Wall lubricating oil series of products are mainly for diesel engines, but the specific product model you still go to their maintenance center or find a technician to ask, as long as it is not a special excavator, it is no problem to use the oil of Great Wall lubricating oil directly.

Hit the handlebar, the big arm and the two arms of the small bucket all received the bottom and put it flat to the ground, open the hydraulic pump door, look at the oil gauge, and the oil is normal in the middle of the two grids, thank you.

You're talking about butter, which is grease, depending on what brand you buy.

The low-grade ones of the Great Wall are cheaper, but they have a short service life and need to be replaced frequently.

Total, the mid-range of the BP class is better than the Great Wall is limited.

Shell or Meifu** are more expensive but have a long service life and are cost-effective.

There is also unity is garbage do not buy, I used to dry the sale of Shell lubricants, unity actually bought Shell expired lubricants with additives when the unified sale is very unreassuring.

The ** of oil products fluctuates with the international oil price, you had better ask the latest**, I used to do it almost 3 times a week, and now I don't know the accuracy of it.

I used to sell 200L barrels and never sold in bulk, and I calculated that a barrel of Shell sold for about 3,000 yuan at that time, and I don't know how it has been.

Take a look at the relevant materials, learn about the various brands and see which one is more suitable for you, so don't let people be fooled.
