Before starting this procedure, gather together all the necessary tools and materials
. Also make sure that you have plenty of clean rags and newspapers handy to mop-up any spills. Ideally, the engine oil should be warm, as it will drain better and more built-up sludge will be removed with it. Take care, however, not to touch the exhaust or any other hot parts of the engine when working under the vehicle. To avoid any possibility of scalding, and to protect yourself from possible skin irritants and other harmful contaminants in used engine oils, it is advisable to wear rubber gloves when carrying out this work. Apply the handbrake, then jack up the front of the vehicle and support it on axle stands. Alternatively, raise the vehicle on a lift or drive it onto ramps. Whichever method is chosen, make sure that the car remains as level as possible, to enable the oil to drain fully. Remove the engine undertray where applicable.
