Passage 4 The first step of changing oil in a car is to gather supplies. After you have collected all of the tools and supplies, prepare your vehicle. Start the car and let it run for one to two minutes to warm the oil and the engine. Then, find a flat surface to jack the vehicle from the center under the engine. Next, locate the oil filter and oil drain plug. Put on work gloves to protect your hands and position an oil drain pan under the engine then remove the plug the rest of the way.
