To change your oil: 1. Gather supplies like new oil and filter specified in your owner's manual, a drain pan, jack, jack stands, and wrenches. 2. Jack up the car, place it on jack stands, and locate the oil filter and drain plug. 3. Remove the oil filter with a filter wrench and drain the old oil from the drain plug into a drain pan. 4. Clean the filter contact surface, apply new oil to the new filter gasket, and hand tighten the new filter. 5. Pour in the specified amount of new oil, start the engine to check for leaks, and properly dispose of the old oil and filter.
