There isn't a single right answer. It depends on exactly what you mean by "completely fill". Once you get the entire filler neck covered, regardless of the lean, it is intended that you can NOT put in any more. If you are really anal about it, you might be able to sneak in a little more but some of it would probably be pushed out when you put the cap on.

I personally think that you can actually get MORE in when it is leaned......if you keep filling until the neck is covered and it won't take any more. THEN it will be a mess when you put on the cap (probably) and if the tank heats up rapidly, the gas might run out with the pressure (somewhere).

Bottom line for me is I ain't gonna try it to really find out. I suspect the difference is pretty small, regardless of which way it goes. The recommended proceedure is to fill in until the gas just barely touches one side of the neck.....when on the side stand .....and I intend to stick to that. If you REALLY want to know, try it for yourself.....but you might want to have a hose handy to siphon off a bit if/when you don't like the result.......and some rags to mop up the spills.
