For engine health, it is necessary to change oil constantly. First of all, get all the essential tools you need such as gloves, a drain pan, breaker bar, socket and filter wrench. To make the drain plug and filter more accessible, one should lift the car above the ground. First, warm up your engine and then turn it off before raising the vehicle. Thereafter, empty the old oil, inspect and replace the plug. Take out the old filter, clean the mounting surface and fix a new one. Next comes lowering down of your vehicle adding fresh oil checking on its level before starting your engine so that it circulates enough oil in it for some minutes. Once you have changed it check for leaks and keep an eye on oil levels at all times Dispose of used motor oils when done properly.
