Start the engine, and let it run for a minute or two to allow the oil to circulate through the filter.

I usually allow the car to sit for about 20 minutes, then check the oil once more. Add oil if necessary. Afterward, it is a good idea to drive for a bit (let the engine get up to operating temperature), then park it on a level surface and let it cool down for a couple hours before checking the oil level once more.

Clean up all your materials. Be sure to recycle your oil at an auto parts store such as AutoZone. Most landfills will have special days when you can take your used oil filter to be recycled.
