Process of changing car engine oil: 1. Remove the underbody guard to expose the oil filter and drain plug, unscrew the drain plug on the oil pan, position the oil collection tank beneath the vehicle to collect the old oil; 2. Use tools to remove the old oil filter by turning it counterclockwise, apply a layer of oil on the rubber gasket of the new oil filter, then install it back in place, tighten the drain plug without excessive force to avoid thread damage; 3. Apply a layer of oil on the rubber gasket of the new oil filter and reinstall it, when adding new oil through the filler port, refer to the vehicle manual for the correct amount.
I enjoy changing the oil myself in my spare time, it's quite fun. First, find a flat surface to park the car, prepare the jack and slowly lift the car high enough to crawl under. Wear gloves to protect your hands, loosen the oil pan drain plug and let the old oil flow into the drain pan. Be careful when removing the old oil filter with a wrench, don't use too much force to avoid damage. Wait half an hour for the oil to fully drain before installing the new filter, apply a bit of new oil on the seal for easier tightening. Then reinstall the drain plug securely to prevent leaks. When adding new oil, check the manual for the correct grade like 5W-30, pour it through a funnel to avoid spills and waste. Start the engine for one minute to check for leaks, then turn it off and verify the oil level is midway on the dipstick. DIY oil changes save money and build skills, but make sure you have all the right tools and take your time.
Last time I went for an oil change, I simply booked an appointment at the repair shop and drove there. The mechanic greeted me, registered my information, and effortlessly lifted the car on the hoist while I waited sipping coffee. He quickly drained the old oil from underneath the car, removed the old filter, and replaced it with a new one in one smooth motion. The new oil was added with precise measurement, and the whole process took less than ten minutes. They even offered free tire pressure checks and battery charging—so hassle-free. The cost was just a few dozen bucks, totally worth it. When I asked why regular oil changes are necessary, they explained that every 5,000 kilometers ensures proper engine lubrication, reduces wear, extends lifespan, and prevents costly repairs. Next time, I’ll definitely choose this shop again for the convenience.
Changing engine oil requires caution as it involves high risks. DIY attempts can be dangerous with unstable jacks potentially causing the car to collapse and injure people. Used oil is corrosive to skin, requiring protective clothing and gloves. Incomplete oil drainage may contaminate new oil and damage the engine. Prioritize safety by opting for professional shops—they have specialized equipment, standardized procedures, and trained technicians for swift, hazard-free oil changes. Spending a little extra ensures major protection against accidents.
