How often should I change the oil if I don't drive much?

If you don't drive much, you should change the oil every six to eight months, as the oil can oxidize and deteriorate when left in the engine oil pan for extended periods. The functions of engine oil are: 1. To separate the surfaces of relatively sliding parts and reduce wear; 2. To carry heat back to the oil tank and then dissipate it into the air, helping the radiator cool the engine; 3. To circulate carbon deposits, sludge, and wear particles from engine parts back to the oil tank, flushing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil. The method for changing the oil is: 1. Lift the vehicle with a jack; 2. Drain the old oil; 3. Remove the oil filter; 4. Install a new oil filter and refill with new oil.
I've been driving for most of my life and I know very well that even if the car isn't driven, the engine oil still needs to be changed on schedule. Engine oil isn't permanent; over time, it oxidizes and deteriorates, absorbing moisture from the air, which reduces its lubricating effectiveness. Internal engine components can rust or wear out, and may even seize upon startup. I recommend changing it every 6 to 12 months, depending on your usage. If the car is parked in a humid environment or garage, the oil deteriorates faster, so it's best to shorten the interval to six months. Don't forget to check the dipstick—if the oil is black or thin, that's a sign it needs changing. A cost-saving tip is to buy synthetic oil, which lasts longer, but don't skimp to the point of neglecting maintenance. Start the car regularly and let it run for a few minutes to circulate the oil and protect the engine. This habit can avoid costly overhauls and extend the car's lifespan.
