What should I pay attention to when changing oil

1. Pay attention to the oil change time.The oil change cycle needs to be judged according to your own car habits. If you drive for a long time, you can replace it in advance. If the vehicle is only used for transportation, you can slow down the replacement time. In synthetic oil, it is recommended to replace semi-synthetic oil at 8,000 kilometers, while in synthetic oil, it can be replaced at 10,000 kilometers or once a year.

2. Choose the right oil. When choosing the right oil, you need to choose it strictly according to the oil level specified in the instruction manual. If there is no oil of the same level, you can only use a higher grade of oil, and never replace it with a lower grade of oil. At the same time, you should pay attention to whether the viscosity of the oil meets the requirements, and don't have the idea of choosing the right one.

3. Different oils cannot be mixed: If the medium and high-end oil is replaced with ordinary oil, the original oil should be cleaned first, and the lubrication system should be cleaned. Do not be mixed.

4. Check the shelf life of car oil. The easiest way to check the shelf life of car oil is to observe whether the viscosity of the oil changes, judge whether the smell of the oil fades, and observe whether the color of the oil changes. Among them, when observing the change of oil color, pay attention to the change of additives in the oil.

The correct way to change the oil of the car

Find the vehicle oil mark, disassemble it, and then wipe the oil near the oil mark with a rag so as not to affect the process of changing the oil. Remove the oil sp shell bolt.

Then unscrew the oil release screw, blow the refueling port with an air gun for two minutes, screw on the oil release screw, wipe it with a paper towel, and check whether there is oil leakage.Finally, install the guard plate, put down the car, and aim the funnel at the refueling port.

First of all, before changing the oil, the car mainly ensures that the temperature of the car is at normal temperature and cannot be replaced after driving. The vehicle needs to be left still for a period of time to precipitate all the oil back to the oil pan.

Lift the car to the appropriate height, open the refueling cover, and remove the oil plug. Discharge the old oil into the container, drain it and rinse it. At the same time, replace the oil filter and tighten the oil release screw. Add new oil, and when it is filled to the line on the oil meter, start the engine, let the oil circulate, and observe whether there is leakage.

Car oil change steps

Buy engine oil Before replacing engine oil, you should first buy a new engine oil. Generally, it is recommended to use the original engine oil, and the quality is relatively guaranteed. In addition, it should be noted that the grade of the oil should be consistent with the model.

Step 1: Turn off the engine after driving the car to the lifter, and then use the lifter to lift the vehicle, pull up the handbrake and squeeze the front wheel with a wooden wedge. Step 2: Place the old oil container under the oil span, find the oil release bolt of the oil sup, slowly unstw the open oil bolt, and be careful not to touch the hot oil. Let the oil drip for a longer period of time.

Steps for changing the oil of the car: First, lift the car, remove the guard, and put a container of about 10 liters under the oil release screw. Then unscrew the oil release screw, blow the refueling port with an air gun for two minutes, screw on the oil release screw, wipe it with a paper towel, and check whether there is oil leakage. Finally, install the guard plate, put down the car, and aim the funnel at the refueling port.

Method/Step 1 Lift the vehicle. In 4S stores and repair shops, use lifts. If you change the oil by yourself, you can use the cushioning method to remove the front chassis guard.2 Put the oil recovery bucket (connect the waste oil container) under the oil change screw at the bottom of the engine. The distance should not be too far, and the waste oil should be within 50cm to avoid splashing out.
