An oil change typically takes around 1 hour. Here is relevant information about engine oil: 1. Oil viscosity (using 0W-20 as an example): (1) The 0W in 0W-20 indicates the engine starting characteristics of the oil. Using oil with a lower number before the W makes it easier to start the engine in cold weather. (2) The 20 in 0W-20 indicates the oil's viscosity characteristics at high temperatures. If the vehicle is driven at high speeds or under extremely heavy load conditions, it's more suitable to use oil with higher viscosity (higher viscosity number). 2. Oil selection: Naturally aspirated engines generally use average quality oil, which can be mineral oil or semi-synthetic oil, while those with larger budgets can use fully synthetic oil. Compared to naturally aspirated engines, turbocharged engines have more compact structures and operate under more demanding conditions, requiring higher-grade lubricants with better fluidity, preferably fully synthetic oil.

As an enthusiast who frequently tinkers with my own car, I have extensive experience in changing engine oil. The time required depends on various factors: If you do it yourself, prepare the tools in the garage—jack, wrench, oil drain pan—the entire process includes draining the old oil, waiting about 15 minutes for the oil to fully drain, replacing the oil filter (some cars have easily accessible filters, making this step quicker), adding new oil, and finally checking the oil level. The total time ranges from 25 to 35 minutes, but beginners might take an extra 10 minutes. At a professional shop, they use equipment to extract the oil much faster, completing the job within 20 minutes, but during peak seasons, waiting in line for half an hour is common; in winter, cold oil flows slower, which may also add time. I recommend making an appointment to avoid peak hours—on average, it takes about 40 minutes, and an hour is usually sufficient. Don’t rush; safety comes first. Additionally, older cars with poor oil quality may require extra effort to clean the oil pan, but regular oil changes help extend engine life.

As an average car owner, I usually go to local quick-service spots for oil changes. Last time, the technician worked swiftly: pulling into the bay, lifting the car, draining the oil (took about 5 minutes), replacing the oil filter, refilling with fresh oil, and doing quick checks like topping up fluids and inspecting lights—all done in under 15 minutes before calling me to pick up the car. However, wait times can vary; that day at noon, a 20-minute queue stretched the total to 40 minutes. Dealerships might add a full chassis inspection, extending it to 50 minutes. I’ve tried DIY at home but gave up due to lacking tools and the hassle of cleaning spilled oil from the garage. Generally, 40–60 minutes is a common estimate at most places, making an hour reasonable. Sticking to scheduled oil changes saves headaches by preventing car issues, and choosing reputable small shops can trim downtime.

I drive my car a lot, so changing the oil is a regular thing. At a quick repair shop, it usually takes 15 minutes: three quick steps—draining the oil, replacing the filter, and refilling. Doing it myself requires finding a flat spot and jacking up the car, which might take 20 minutes, but it can be tough if the oil filter doesn’t come off easily. The location makes a difference—an easy-to-reach filter saves time. At a professional shop, an hour with waiting is often considered enough, but with an appointment, it can be done in 30 minutes. Regular oil changes keep the engine healthy.
