Precautions for Changing Engine Oil in Cars
2 Answers
Precautions for changing engine oil in cars are as follows: 1. When to change the oil: Under normal driving conditions for a new car, if synthetic oil is used, the oil can basically be changed every 10,000 kilometers, and some can even go up to 20,000 kilometers. Automotive maintenance professionals believe that "normal driving" refers to frequently driving on highways with few stops and starts. However, if you often drive in the city, encountering traffic lights everywhere and frequent traffic jams, with most trips not exceeding more than a dozen kilometers, this type of driving is considered "severe driving." Under "severe driving" conditions, engine wear is greater, and the requirements for oil are higher. Therefore, it is recommended to shorten the oil change interval to effectively protect the engine. 2. How to choose engine oil: Choosing good oil can make the car more durable and powerful. Good oil, especially fully synthetic oil, not only protects the engine and reduces the frequency of oil changes but also saves on gasoline expenses.
I find changing engine oil by myself is the most satisfying, but safety details must be noted. Always refer to the vehicle manual for the recommended oil grade, like 5W-30, and never buy the wrong brand to avoid engine damage. Essential tools include gloves, wrenches, and a drain pan. Warm up the engine for a few minutes to thin the oil, but be careful not to burn yourself. Loosen the drain plug gently to avoid damaging the threads. After the old oil drains completely, replace the filter and apply a bit of new oil on the new filter's seal to prevent leaks. Pour new oil slowly and use the dipstick to check the level up to the midpoint—overfilling can cause smoke and damage. After finishing, start the car for a few minutes to check for leaks under the chassis. Never dispose of old oil improperly; take it to a professional recycling center. Keep the car stable throughout the process to prevent movement. DIY saves money and gives a sense of achievement, but beginners should watch tutorial videos first to learn the basics.
