How Long Does It Take to Change Engine Oil in a Car?

Generally, it takes about half an hour to one hour to complete an engine oil change, which is considered a minor maintenance task and is relatively simple to perform. Below is more related information: 1. Types of Engine Oil: The notion of changing oil every 5,000 kilometers is a one-size-fits-all approach and not scientifically sound. Currently, there are three main types of engine oil available on the market: full synthetic, semi-synthetic, and conventional oil. Full synthetic oil should be changed every 10,000 to 15,000 kilometers; semi-synthetic oil every 7,500 kilometers; and conventional oil is recommended to be changed every 5,000 kilometers. 2. When to Change Engine Oil: For new cars in the break-in period, it is advisable to change the oil every three months, regardless of whether the 5,000-kilometer mark has been reached, to promptly remove fine metal particles generated during engine break-in. For older vehicles, changing oil every 5,000 kilometers is quite frequent. Considering the quality of fuel and air filters in China, changing oil every 7,000 to 8,000 kilometers is more appropriate. For cars that are frequently left idle, it is recommended to change the oil every 5,000 kilometers. In fact, for full synthetic oil, the period between 5,000 and 8,000 kilometers is when the oil reaches its optimal viscosity stability and performs at its best.
I remember the last time I went to a quick service shop for an oil change, the whole process from driving in to driving out took about 15 to 20 minutes. They first checked my car model—my small car has a compact engine. The technician skillfully lifted the chassis, drained the old oil, replaced the oil filter in passing, and then refilled with new oil. The speed mainly depends on the technician's experience; a novice might take over 30 minutes, especially if there's a queue or the car model is complex. I think making an appointment is a good idea, as it can save a lot of waiting time; doing it yourself is also an option, but you need specialized tools like a jack and an oil drain pan, and beginners can easily make a mess by leaking oil. For safety, it's better to work on a cold car—don’t start right after driving, or the risk of burns is high. Overall, a standard oil change plus basic inspection can often be done within 20 minutes, but don’t rush at the expense of oil quality—an oil change significantly impacts engine lifespan.
