How Often Should You Change the Oil in a New Car?

[TeaganRose]

For a newly purchased car, the oil should be changed approximately every 6 months or after driving around 5,000 kilometers. The steps for changing the oil are as follows: 1. Lift the car, remove the underbody shield, and place a container beneath the oil drain plug; 2. Unscrew the oil drain plug, use an air gun to blow for two minutes at the oil filler port, then tighten the drain plug after the oil has completely drained and wipe it with a tissue to check for leaks; 3. Reinstall the underbody shield and lower the car, then use a funnel to add new oil through the filler port. The functions of engine oil include: 1. Separating the surfaces of relatively sliding parts to reduce wear; 2. Carrying heat back to the oil pan and dissipating it into the air to help the radiator cool the engine; 3. Circulating carbon deposits, sludge, and worn metal particles from engine components back to the oil pan, flushing away contaminants generated on the working surfaces of the parts through the flow of the lubricating oil.
