Have everything you require before beginning, rags or newspapers to clean up the spills. A hoist, ramps or jack stands are used to gain access to the underside of the vehicle. Get to know where the oil drain plug is but remember that the engine and exhaust parts are hot. Park the car in a flat area, turn on the engine until it attains normal working temperature and switch off. Lift the car and hold it in position. A drain pan should be carefully placed beneath the drain plug, and the plug is removed with the right wrench and the old oil should drain out and the drain should be checked whether it has any metal shavings. Once emptied, wipe down the drain plug and surrounding, replace the plug, and place the drain pan beneath the oil filter.

Take off all the tools and rags that are beneath the vehicle, lower, and pour in new oil with the help of a funnel after using the filler cap. Wait some few minutes, inspect the dipstick in the oil and when the oil is at the level of full, turn on the engine to pump the new oil. Once the engine has been running, after approximately one minute, confirm there are no leakages at the drain plug and oil filter, and tighten them as required. Check the level of oil again and pour more oil. The first several trips to check the leaks and the oil level after changing the oil. Discard the old oil in a proper way, but not reusing it and putting it in a recycling facility, not pouring it down the drain or the ground.
