A: As a home mechanic, replacing the oil at regular intervals is an essential preventative measure because old and contaminated engine oil will cause premature wear of the engine. If you desire convenience and cost effect, change the oil filter each time you change oil. Before you begin this process, it's necessary to have with you clean rags, newspapers and other materials and tools required for changing oils. Warm up your car's engine to its normal temperature then safely raise it on jackstands. Some oil drain plug should be recognized by sight while others' locations might need a little bit of research as well as pointing a drain pan underneath them. After that carefully remove the plug, allow the oil to drain off then clean both the plug and its surrounding areas before fixing it back tightly. Put your drain pan under your oil filter then use wrench in unscrewing and removing the old filter ensuring that it is free from any oil residue. Examine both filters to ensure compatibility and maintain cleanliness around mounting area of filters Use fresh motor oil to lubricate the rubber gasket of a new filter lightly before installing it according to tightening instructions given by its manufacturer. Lower vehicle, find the cap filled with new oils then pour in enough amount of oils. Look at the level of oils after some few minutes and start an engine for couple of seconds while checking for any leakage. Any wrong disposal of used oils is harmful since they cannot be reused again.
