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

[MacNathan]

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.
