Recently I started performing my own oil changes on my RV. To make this chore a lot easier, I installed a device called a Fumoto drain valve. The Fumoto valve simply replaces the drain valve on your engine's oil pan and enables you to drain your oil quickly and with no mess. You don't even need any tools as you'll see in the video.
I got my Fumoto F-106 valve on Amazon: http://amzn.to/1pkJ9V4
If you are thinking of saving time and money by performing your own oil change, I strongly recommend you install one of these valves. There are a few options to choose from so go to the Fumoto website (http://www.fumotousa.com) to find the model that fits your engine.
Routine oil changes are a breeze for me now. I simply pick up the oil and filter from Walmart and do a quick oil change when I need to.
