    1. Moderate dosage.

    Most of the transmission components such as transmissions, reducers, and steering gears of motor vehicles are oil-immersed. If the lubricating oil filling exceeds the specified limit, the stirring resistance of the gear during operation will increase, which will cause power loss and increase fuel consumption. Therefore, the amount of lubricating oil must be moderate.

    In addition, some people stuff the inner cavity of the wheel with grease when maintaining and repairing the wheel hub bearings of motor vehicles, thinking that the more grease, the better. In fact, adding too much grease to the wheel hub will have many adverse consequences, one is to increase the running resistance of the bearing; the second is to affect the heat dissipation of the bearing; Third, the grease melted due to high temperature may penetrate into the brake drum and cause motor vehicle brake failure. Therefore, "hollow hub lubrication" should be implemented, that is, only grease needs to be applied on the bearing, and no grease is stuffed in the cavity, which can not only ensure the lubrication effect, but also save 5 grease.

    2. Control the viscosity.

    In fact, high-viscosity lubricants can increase mechanical friction losses. Especially at start-up, because the oil has poor fluidity at low temperatures, the frictional resistance is large, which increases the power loss and increases the fuel consumption. If a lower viscosity lubricant is used, the friction consumption inside the oil can be reduced without increasing the wear of the parts.

    According to the test, the viscosity of the engine oil is reduced by one level, and the fuel saving rate of the engine is 1%-3%. Therefore, lubricating oil with lower viscosity should be used on the premise of ensuring lubrication.

    3. The price should be considered.

    Some drivers want to save money, often only see the price of oil and immediate maintenance expenses, and ignore the increased repair costs in the future. When choosing a lubricating oil, the quality grade of the lubricant should be selected according to the speed, the size of the load, and the type of gear transmission. The performance indicators of high-grade lubricating oil are superior, so it can significantly extend the service life of the machine and the oil change interval, and reduce the maintenance cost.

    Especially when a motor vehicle is fully loaded for a long time and works in poor road conditions, it is best to use a lubricant quality grade that is one grade higher than that specified in the manual.

    The use of lubricating oil is mostly divided into industrial lubricating oil and medical lubricating oil, if it is an industrial lubricating oil, it is generally used in various machines, which are generally liquid. Pour directly over the place where lubrication is needed, and pour an appropriate amount on it. If it is a life in which lubricating oil is divided into paste and liquid.

    Apply the paste a little by hand and apply it to the area where it needs to be lubricated. If it is liquid, it can be used by sticking it with a cotton swab.

    Can you ask in detail, because you don't explain what kind of lubricating oil, it is difficult to help you, do you ask about the lubricating oil of the car or what, there are a lot of lubricating oil, I don't know what kind of lubricating oil you are asking, you can explain, so that you can help solve the problem of lubricating oil.

    (1) Regular inspection and timely replacement.

    With the passage of time of the machine, the lubricating oil in the refrigeration system will continue to change qualitatively, so regular sampling and laboratory analysis, or color and phase comparison inspection, when the oil quality changes to a certain extent, it should be replaced in time. Under normal circumstances, the lubricating oil in the refrigeration system should be changed once a year.

    2) Oil change requirements.

    Look for the brand of new oil change, it is best not to easily change the brand of refrigeration oil, and it is strictly forbidden to use general engine oil instead of refrigeration oil.

    Before replacement, all the oil in the system is released, and some new oil is added, and all the old oil remaining in the system is washed and released, so as to prevent the original oil from destroying the performance indicators of the new oil and affecting the service life of the unit.

    When changing the oil, try to drain the remaining oil from the oil cooler. Thoroughly remove sediment and rust in the oil tank and air extraction device, and disassemble, inspect and clean the oil pump and filter to ensure that the replaced lubricating oil is clean and pure, and well lubricated.

    3) Precautions to be taken when using the product.

    During the shutdown of the unit, when the lubricating oil and refrigerant coexist in the system, the oil lubricating oil should be energized and heated to keep the oil temperature within the specified range.

    In winter, when lubricants and refrigerants coexist within the system, how they are managed should be determined by the type of aircraft. Centrifugal chillers, especially centrifugal chillers with R11 as the refrigerant, should keep the electric heater energized to stabilize the oil temperature within the specified range. The screw and piston chillers can not be energized to the electric heater, and then turn on the power supply of the oil heater before use, heat for 24h, and then start the machine.

    Hello, I am glad to answer for you that most of the transmission components such as transmission, reducer, and steering gear of motor vehicles are oil-immersed. If the lubricating oil filling exceeds the specified limit, the stirring resistance of the gear will increase, which will cause power loss and increase fuel consumption. Therefore, the amount of lubricating oil must be moderate.

    Summary. Hello dear, I'm honored to answer for you <>

    How to use lubricating oil: How to use automobile lubricating oil: 1. The car stops and turns off for about ten minutes, pull out the oil dipstick, and wipe the oil stains on the ruler with a cloth; 2. Insert the oil dipstick back into the dipstick tube, pull out the dipstick again, and check the oil stains on the dipstick.

    Under normal circumstances, the oil stain should be between the upper and lower engraved lines of the dipstick, and the middle line should be up; 3. If the oil stain is under the lower engraved line, it means that the oil quantity is insufficient and should be refueled immediately, and the oil dipstick should be continuously pulled out when refueling to observe the addition of oil; 4. When adding engine oil, it is necessary to pay attention to the consistency of the engine oil and the engine oil as much as possible, so as to avoid mixing different brands and varieties of engine oil.

The car stops the rock fire for about ten minutes, and Pei shouts to pull out the oil dipstick and wipe the oil stains on the ruler with a cloth; 2.

When adding engine oil, it is necessary to pay attention to the consistency between the engine oil and the engine oil as much as possible, and avoid mixing and matching different brands and varieties of engine oil.

    I hope it will be helpful to you in the following related developments: automotive lubricants are divided into mineral lubricants, synthetic lubricants, semi-synthetic lubricants and other categories. Lubricating oil is made of natural gas and hydrocarbons refined, and there is no clear definition of synthetic oil buried in the world.

    High-grade lubricating oil is synthetic lubricating oil, synthetic oil has the following advantages (but ** is high) 1. Hydrogenated base oil removes impurities that affect the quality of lubricating oil, and its performance is stable. 2. Improve power, reduce noise, save fuel than conventional lubricating oil 3. The fluidity of oil is twice that of traditional lubricating oil, so that the low-temperature local potato starts more quickly. 4. Excellent oxidation resistance and thermal stability, suitable for use under high temperature and harsh conditions.

    5. Excellent anti-abrasion, anti-bending wax friction agent formula to prolong the service life of the equipment. 6. Long-term use of clean carbon deposits to ensure that the engine is clean and the oil change period is extended.
