Regular changes in oils will prevent engine wear and tear. Gather together the tools and materials, jack up the vehicle, and locate the oil drain plug and filter. First, warm the engine; second place a drain pan under the plug, remove it. The first one is draining the oil, cleaning the plug, and reinstalling it. The next step is to position the pan under the filter, remove it, and compare it with the new one. The sixth can be described as cleaning off the filter area, applying oil to the gasket of new filter and installing it in there. Finally, lower down your vehicle; pour some fresh oil into it and check out its level. Start up your engine; look around for any leakage or faults before you may need them changed again in the future (IF). Then monitor the oil level after this step and dispose of these harmful chemicals well in that respect (FF1).
