I decided to add oil to the fuel as I do the fill up back when I was building.  That was not a problem for a long time because I was buying fuel in a couple of 55 gal drums and hauling them on a trailer.  I would add the oil to the drum before I left the hangar to go to the gas station and then just fill the drums.

The first time that I tried to do this at an airport, it turned out to be a PITA!   The wind was blowing and it was cold and the oil was stringing out all over me and the wing.  Quite a mess!

This makes me start to think of how can I measure and add this oil in a neat clean and easy way.  Now I know I am not the first guy to try and gas up on a windy day so has anybody figured out how to do this in a cute way?

I discovered a long time ago that the best inventions I can come up with come off this list.  How do you guys do this?
