Can I change my car's engine oil by myself?
2 Answers
You can change your car's engine oil by yourself, but if the car is under warranty, you must go to a 4S shop. Otherwise, if any problems arise, the 4S shop will not provide warranty service. If the car is not under warranty, you can go to a repair shop or do it yourself. Many people think that changing the oil by themselves is quite difficult and are hesitant to try it. In fact, as long as you master the correct procedures and use specialized tools and equipment, changing the oil yourself is not a difficult task. The following are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. 3. Rust prevention: Lubricating oil can adhere to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the piston, piston chips, connecting rod, and crankshaft bearings, this load is transmitted through the bearings' lubrication, cushioning the impact load. 5. Cleaning: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, and by the flow of the lubricating oil, it washes away dirt generated on the working surfaces of the parts.
Yes, changing your car's oil yourself can be a fun DIY project. Preparing the right tools is crucial: new engine oil, an oil filter, an oil drain pan, a wrench, and safety stands—don’t forget to wear protective gloves. Find a level spot, secure the car with stands for safety, then loosen the drain plug to let the old oil flow out completely, making sure to catch the used oil in the pan to avoid spills. Next, replace the oil filter, applying a bit of new oil to the filter’s gasket to prevent leaks. Before adding new oil, check the dipstick markings and pour the correct amount as specified in the manual—avoid overfilling or underfilling. The whole process requires patience; it may take 40 minutes for first-timers but just 20 minutes once you’re experienced. Used oil must be disposed of at a recycling center—it’s both eco-friendly and legal. Regular oil changes every 5,000 km can extend your engine’s lifespan, save money, and boost your sense of accomplishment. Beginners should start with basic tools and prioritize safety. This is also a good opportunity to inspect the undercarriage for damage, such as oil leaks, killing two birds with one stone.
