Can I change the engine oil myself?
2 Answers
Yes. Here is the relevant introduction about engine oil: Function: Engine oil, also known as engine lubricant, can lubricate and reduce wear, assist in cooling, seal and prevent leakage, prevent rust and corrosion, and provide shock absorption for the engine. Classification: Gasoline engine oil is divided into mineral oil and synthetic oil, with synthetic oil further categorized into semi-synthetic and fully synthetic oil. Composition: Engine oil consists of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, giving it certain new properties, making it an important part of lubricating oil.
I always thought changing engine oil wasn't difficult, but when actually doing it, it really tests your patience. You need to prepare the tools: hydraulic jack, wrench, oil filter wrench, gloves, and a large container for the waste oil. First, lift the car to ensure safety, unscrew the oil pan bolt to drain the old oil—it flows more easily when warm. Then replace the oil filter, which is a key point—don't install it backwards. When adding new oil, use a measuring cup to pour it in carefully to avoid spills, and check the dipstick to ensure the right amount. Disposing of the waste oil is a bit troublesome—it needs to be taken to a recycling center, don't just dump it and pollute the environment. The whole process takes over half an hour and can save you two or three hundred bucks in labor costs, which is quite worthwhile. But remember, safety first—make sure the ground is level, wear anti-slip shoes, and don't get distracted by your phone. I've done it myself a few times—at first, I was nervous and shaky, but gradually got the hang of it, feeling a small sense of accomplishment.
