How Often Should You Change the Oil if You Don't Drive Often?

If you don't drive often, you can change the oil once a year. Here's how to choose the right oil: Oil Dipstick Indicators: The oil dipstick has two marks: a maximum level and a minimum level. The proper oil level should not exceed the maximum mark or fall below the minimum mark. The oil level should be between these two marks. How to Check the Oil: After adding oil, start the vehicle and then turn it off. Wait for 3 minutes before checking the oil level. This is because when changing the oil, the oil filter is also replaced, and the new filter initially contains no oil. Starting the vehicle allows oil to flow into the filter. Waiting 3 minutes ensures the oil settles into the oil pan, providing a more accurate reading. Avoid checking the oil on a slope, as the tilted position of the vehicle causes the oil in the pan to tilt as well, leading to an inaccurate measurement.
I've seen many friends' cars parked in the garage all year round, and they always think that low mileage means no need to change the oil. This is actually a misconception. Once opened, engine oil gradually oxidizes and deteriorates, especially oil older than six months, whose lubrication effectiveness drops significantly. Last time I helped a neighbor check his car, which hadn't had an oil change in eight months, the oil was as thick as syrup, and sludge had formed in the oil pan. Even if you don't drive, it's recommended to change the full synthetic oil at least once a year, and also check the condition of the coolant and brake fluid, as these fluids naturally age over time. For cars that are parked long-term, don't forget to let the mechanic run the engine for a few minutes during the oil change to allow the new oil to fully circulate and coat the engine's internals.
