An oil change for a car typically takes about 1 hour. Method for changing oil: When adding oil, ensure the oil level is between the min and max marks on the dipstick. The oil level should not be below the min mark or above the max mark. If the oil level is below the min mark, it can lead to insufficient lubrication, accelerating engine wear. If the oil level is above the max mark, it increases engine resistance during operation, resulting in reduced power and higher fuel consumption. Always check the oil level carefully when adding oil. Precautions for oil changes: Oil should be changed regularly, and different types of oil should not be mixed. Purchase high-quality full synthetic oil, which should be changed every 8,000-10,000 kilometers. Semi-synthetic oil should be changed every 5,000-8,000 kilometers, while mineral oil should be changed every 5,000 kilometers. Regularly clean the engine air filter and replace the oil filter. After adding oil, sludge and carbon deposits on engine parts disperse into the oil, causing it to turn black over time. The need for an oil change should be determined by checking the oil's viscosity rather than its color. Insufficient oil can lead to inadequate lubrication and cylinder scuffing, while excessive oil can reduce vehicle performance and increase fuel consumption.

The time it takes to change the oil really depends on the situation. If I go to a repair shop, it usually takes about half an hour, including draining the old oil, replacing the filter, and adding new oil. If I make an appointment in advance, there's no waiting, and it's even quicker. If I do it myself, it's also simple: lift the car, unscrew the oil pan drain plug, drain the old oil, replace the filter, pour in new oil, and it's done in just over ten minutes. But safety is important—make sure to have gloves and tools ready. Some models, like SUVs or older cars, might take a bit longer due to tight spaces or rusted parts. Remember, don't rush; doing it properly keeps the engine healthy and extends the car's lifespan. Generally, it's recommended to change the oil every 5,000 kilometers or six months—don't slack off!

I've changed engine oil countless times, and experience tells me that at professional service stations, a full set of services usually takes about 20 to 25 minutes, unless the staff is busy or there are additional inspections. Doing it yourself is even faster, taking less than 15 minutes, but you must ensure the quality of the new oil is good and the quantity is accurate. Many factors affect the time: the age of the vehicle, the oil brand, and whether the filter is replaced. For example, small cars are quicker than large trucks. By the way, oil changes don't just take little time; they also allow for checking tire pressure, brake fluid, and the like, killing two birds with one stone. Making it a habit can save you from major repairs later on, and a well-maintained car gives you peace of mind while driving.

As a regular car owner, an oil change typically takes 15 to 20 minutes at a quick-service shop. It's not time-consuming and fits well into a busy schedule. Specifically: a basic oil change is quick; adding a filter replacement adds a few more minutes. A reminder—peak hours might involve waiting, so going early or visiting on weekdays avoids crowds. This simple yet efficient procedure is crucial for maintaining engine lubrication, especially worth checking before long trips. Regular oil changes prevent wear and tear, making car maintenance worry-free and effortless.
