A high -quality lubricant can play the role of lubricating engine and extend the service life of the engine.Only high -quality and sufficient lubricating oil can carry us to any place, travel, or work.And how to use lubricating oil correctly cannot be underestimated.So, how to replace lubricating oil?What are the misunderstandings of lubricating oil?Lets take a look today.
How to replace lubricating oil
Step 1: Run the engine to achieve the working temperature.Then use the jack to push the vehicle, pull up the hand brake and squeeze the front wheel with a wooden wedge.
Step 2: Place old oil containers under the oil bottom shell to find the oil bolt of the oil bottom shell, and slowly twist the oil bolt, be careful not to contact the thermal oil.Let the oil be dropped for a while.Check the oil bolt and reinstall the oil bolt. Be careful not to twist the bolt too tightly to prevent the oil bottom of the shell from damaging.
Step 3: Move the oil container below the oil filter, use the oil filter element wrench to loose the filter element and remove it with your hand.If the filter element is still hot, remember to wear gloves.Dont worry about the filter element tightly, the filter element will be damaged during the disassembly process.As long as it is not damaged, the interface screw of the filter element and the parts around the filter element can be.After all, we will no longer use the removed filter element.
Step 4: See the appropriate oil filter element with reference to the users manual.
Step 5: Apply the interface ring of the new filter element with the new oil.If the filter element is installed vertically, some new oil can be poured into the filter element, so that the dry grinding can be reduced when the engine starts next time.Twist the filter element by hand, and tighten the filter element according to the indication method (usually tightened the filter element with the hand before screwing into 3/4 laps).
Step 6: Next, refer to the introduction of the new engine oil to the bottom of the oil, refer to the introduction of the users manual.You can use funnel to prevent the oil from the outside of the engine.Check if there is a leak in the lower part of the engine.If there is no leak, put down the vehicle, check the oil ruler, and start the engine.The indicator light on the instrument should be extinguished immediately.Finally, turn off the engine and check the amount of oil.Treatment of old oil and filter elements according to local regulations.
Use misunderstanding of lubricating oil
Misunderstanding 1: If the lubricant can add more, add more lubricating oil, and the amount of lubricating oil should be controlled between the upper and lower section of the oil ruler.Because too much lubrication oil will enter the combustion chamber from the gap between the cylinder and the piston to form a carbon accumulation.These carbon accumulation will increase the engine compression ratio and increase the tendency of explosion; the carbon accumulation in the cylinder is red thermal state, which can easily cause early burning. If it falls into the cylinder, it will exacerbate the wear of the cylinder and piston, and will also accelerate the pollution lubricating oil.Secondly, excessive lubricating oil increases the stirring resistance of the crankshaft connecting rod to increase fuel consumption.
Misunderstanding 2: When the lubricating oil becomes black, it should be changed. This understanding is not comprehensive.For lubricating oil without a net dispersant, the color becomes darkened is indeed a serious performance of the oil products, but the lubricant used by modern cars generally adds a clean decomposition agent.This kind of cleaning agent was washed with the glue film and black charcoal that was adhered to the piston, and scattered in the oil to reduce the production of the high temperature sediment of the engine.Oil products are not completely deteriorated.
Misunderstanding 3: Lubricating oil often does not need to be replaced. It is correct to check lubricating oil. However, it can only be supplemented without replacement. It can only make up for the lack of oil in the number of oil, but it cannot completely compensate the loss of lubricating oil performance.During the use of lubricating oil, due to pollution, oxidation and other reasons, the quality will gradually decrease, and there will be some consumption to reduce the number.
Misunderstanding 4: The use of additives is large and highly high -quality lubricant is a finished product with a variety of engine protection functions. The formula already contains a variety of additives, including antigeningPlay.Adding other additives on its own not only cannot bring additional protection to the vehicle, but it is easy to react with the chemicals in the oil, resulting in a decline in comprehensive performance of the oil.
Lubricating oil inspection method
1. Check the lubricant lid to unscrew the fuel mouth and turn it over to observe the bottom. This can see the traces of old oil or even dirty oil at the bottom of the fuel mouth cover.If there is a layer of dark dairy with viscosity and small water droplets mixed with oil dirt at the bottom of the lid of the mouth cover.Caused by lubricating oil.If this happens, the polluting lubricant will cause harm to the internal engine and need to be repaired.
2. Check the amount of lubricating oil. If there is no problem with the lid of the refueling mouth, then pull it out after finding the lubricant, first check the oil surface. The height of the oil surface should be in the position of "full" or "full".If the oil surface is too low, the engine will be damaged due to poor lubrication, and it will cause damage to the valve, cylinder pads, and piston rings.Observe whether the ground at the bottom of the car has a leakage lubricant. If there is conditions, you can detect the pressure of the cylinder to see if there is leakage and cause damage to the engine parts.
3. If the tail gas is checked, the tail gas is blue smoke, indicating that the valve oil seal is ineffective, and the lubricant enters the cylinder burning room; it may also be a failure of the piston ring and the cylinder wall or the piston ring.The aging and damage of the seal and oil seal cause the lubricating oil to leak and consume too much lubricating oil.
4. The lubricant color can take out a paper towel, pull out the lubricant ruler and wipe it on the paper to observe the color and impurities of lubricating oil.Generally, after changing lubricating oil, the vehicle will turn black after a period of time, which is normal.Other colors are abnormal.If the color of the lubricant becomes gray, white, or emulsified, it means that mixing water in lubricating oil.It may be that the engine cooling system and the combustion system have a leakage.
