Every oil change for me is a one handed endeavor, since I only have one arm.Yes its that easy, practically a one handed endeavor.
A couple of things I do differently....
1. I do the filter first on my Audi. When I unscrew the filter housing mine is hand tight when properly torqued and aligns with the factory paint pin mark every time so I dont even get the torque wrenches out any more.
2.I get my first beer. Once the seal is cracked on the filter housing I can hear a slight gurgling of oil back into the engine (drain back valve?) so this gets more oil back into the sump. Additionally there is a couple tablespoons of oil that can be sucked out of the base of the housing and as soon as it is clear I stick the suction tube into the dipstick tube. The Audi has no dipstick though just a cap.
3. While the sump is being drained I do the filter and o ring change.
4. Once I'm done with the filter I let the sump drain until it starts sucking air. And get beer number two ready.
5. Once beer two is completed I repump the extractor and move the tube around a bit to clear the additional oil that has drained during the second beer.
6. Once the sump is empty I replace the dipstick tube cap and start adding oil. I put about half a litre carefully into the filter housing to possibly get some oil into the lines coming to the filter and reinstall the filter housing and align the marks which is a firm hand tight. I dont think it probably makes any difference but it makes me feel better. I then put the remaining 5 litres into the sump and get on with life.
The only messy part of the whole operation is changing the O ring on the filter housing.
