Steps to change the oil, steps to change the oil

First, an old oil container is placed under the oil pan in the lower part of the vehicle's engine compartment. Use a special wrench to unscrew the oil filter element and take it out, the position of the oil filter element is different for different models.

Slowly unscrew the drain bolt of the oil pan and release the old oil. After a period of release, reinstall the drain bolts and do not overtighten the bolts to prevent damage to the oil pan.

After putting it clean, tighten the screws, not too tight, and then come out and pour the oil into the engine, and the filter can be screwed on. After pouring the oil, remember to check the dipstick.

The method of choosing automobile engine oil: the first is how to choose gasoline, and the engine oil composition: it is composed of two parts: base oil and additives.

Most of the base oils are mineral oils, and additives include metal detergents, antioxidant and anticorrosive agents, rust removers, ashless dispersants and viscosity index improvers.

Selection according to the regional seasonal temperature: The selection of engine oil should be based on the regional seasonal temperature, combined with the performance and technical conditions of the engine, and the appropriate oil label and viscosity grade.

Hello, the operation steps for changing the engine oil are as follows:

1. After the car is driven to the lift, turn off the engine, use the lift to jack the vehicle, pull up the handbrake and squeeze the front wheel with a wooden wedge;

2. Place the old oil container under the oil pan, find the oil drain bolt of the oil pan, and slowly unscrew the oil drain bolt, taking care not to touch the hot oil;

3. Move the oil container to the bottom of the oil filter, use the oil filter element wrench to loosen the filter element, and then unscrew it by hand. If the filter is still hot, remember to wear gloves;

4. Refer to the user's manual to select the appropriate oil filter element;

5. Use new oil to apply the interface gasket of the new filter element. If the filter is installed vertically, some fresh oil can be poured into the filter, which will reduce dry grinding the next engine start;

6. Pour the new engine oil into the oil pan, pay attention to the introduction of the user's manual. A funnel can be used to prevent oil from being poured on the outside of the engine.

The steps to change the oil are as follows:

1. Select the appropriate oil, drain the oil and check. When choosing the right engine oil, you need to choose the oil grade in strict accordance with the car instruction manual, if there is no same level of engine oil, you can only use a higher grade of engine oil, and never use a lower grade of engine oil instead. At the same time, we should pay attention to whether the viscosity of the engine oil meets the requirements, and do not have the idea of choosing the right one, one barrel of AirMaster engine oil is enough.

After the technician twists the oil pan screws or twists the oil filter to release the waste oil, it is necessary to pay attention to: match the oil pan screws with a new screw washer and then tighten it; Before installing the new oil filter, it is necessary to carefully check whether the rubber sealing ring of the original old filter is removed with the filter, so as to avoid oil leakage when the new part is installed. 2. Add an appropriate amount of engine oil.

When adding engine oil to your car, you need to add engine oil appropriately according to the displacement of the vehicle, and you must not be greedy to add too much, or add too little in order to save money. If there is too much oil, it will cause internal power loss when the engine is started, and it will cause problems with burning oil. On the other hand, if the engine oil is insufficient, the internal bearings and journals of the engine will rub due to insufficient lubrication, which will aggravate the degree of wear, and in severe cases, it will cause the accident of burning the shaft.

Therefore, when adding engine oil, it should be controlled between the upper and lower engraved lines of the oil dipstick.

1. First of all, you should go to a regular place to buy suitable engine oil, ensure that the engine oil has not expired, and then you can prepare to place the old engine oil. When placing old engine oil, in addition to preparing a container for old oil, you should also pay attention to the location of the oil, which should be under the bottom shell in the lower part of the engine compartment of the vehicle.

2. After unscrewing the oil drain bolt, release the old engine oil, and when the old oil basically does not flow out again, install the oil drain bolt again, and do not press it too tightly during installation.

3. Use a tool to unscrew the oil filter element, and then take it out, the position of the oil filter element may be different for different cars, and you can understand it before taking it out.

4. After tightening all the screws, pour the new engine oil into the engine oil tank, and the amount added should be in the middle of the highest scale and the lowest scale, not lower than the lowest scale mark, nor higher than the highest scale mark.

In addition to changing the oil properly, it is also important to change the oil filter every time you change the oil.

Step 1: Run the ** motor to bring it to the working temperature. Then use a jack to jack up the vehicle, pull up the handbrake and squeeze the front wheels with a wide wedge.

Check the drain bolts, reinstall the drain bolts, and be careful not to overtighten the bolts to prevent damage to the oil pan.

Step 3: Move the oil container under the oil filter, use the oil filter wrench to loosen the filter, and then unscrew it by hand. If the filter is still hot, remember to wear gloves;

Even if the filter element was tightened before, there is no need to worry about damaging the filter element during the removal process, as long as it does not damage the connection screws that install the filter element and the parts around the filter element, after all, we no longer use the removed filter element.

Step 4: Refer to the user manual to select the appropriate oil filter.

Step 5: Apply the interface gasket of the new filter cartridge with new oil. If the filter is installed vertically, you can pour some fresh oil into the filter to keep it in hand and reduce dry grinding the next engine start.

Screw the filter element in by hand, and tighten the filter element according to the instructions of the mausoleum hall (usually after tightening the filter element by hand and then screwing it in 3 or 4 turns).

Step 6: Pour the new oil into the oil pan, taking care to refer to the user's manual. A funnel can be used to prevent oil from being poured on the outside of the engine.

Check the lower part of the engine for leaks. If there is no leak, put down the vehicle, check the dipstick, and start the engine, the indicator light on the gauge should turn off immediately after starting. Finally, turn off the engine and double-check the oil level and dispose of the old oil and filters according to local regulations.

As long as there are tools and suitable places, you can change the oil by yourself if you know the basics, but car maintenance is not just about replacing the oil, it is recommended to enter the maintenance unit to do a good job, the so-called professional people do professional things, this small money can not be saved, and there is no meaning. Well, to get back to the point, the first thing to do is to lift the vehicle up for oil replacement, and if you don't have the conditions, you can find a step or groove, and first unscrew the oil filler cover, and some cars need to remove the engine cover to see. Then unscrew the oil pan oil gong bolt, pay attention to some vehicles have gaskets or springs, don't lose it, and finally use a plate to catch the discharged engine oil until it flows clean, and at the same time remove the machine filter and replace it with a new machine filter and tighten it, and finally tighten the oil drain gong bolt, do not use too much force, wipe clean and drip oil, and then put the vehicle in a horizontal position chain high filling oil, check whether the oil dipstick is enough, do not too much or too little.

Finally, check whether there is any leakage of the oil drain gong bolt, and replace it if there is no leakage.
