Bill, most hobby shops sells small, battery operated pumps for refueling model airplanes.  Integrate one with a six-pack type carry-all that would hold several quart sized bottles of 2-stroke oil.  Put a compression fitting about 8 inches up on a piece of 3/8" tube, pass through a hole drilled in the top of one of the 2-stroke bottles, then add another compression fitting on the other side.  Then, rout the tube to the pump.  Another length of tube to carry oil to the fill port.

-Fill the caddy with 2-stroke oil bottles, and sit on the wing next to the fill port.

-Pop the top on a bottle, then screw on the top with the hose passing through.

-Switch on the pump while fueling.

-Switch the pump off when the desired amount of oil has been fed in.

-Plug the free end of the hose that fed the fuel fill port into a blind nipple on the side of the caddy (so stray oil doesn't drain out) and place the whole caddy in your storage compartment.

I was thinking of something along this line.  The pump screws onto a 38MM neck which, I think, is the size of a standard gallon bottle.  They sell them for quart and other size bottles as well.  The pump delivers one ounce per squirt and the pump can be locked down when not in use.  If you attached a short tube to the end of the outlet of the pump and had a convenient way to plug the hose when not in use to prevent leakage…

 

I envision setting the jug of oil on the wing by the fuel inlet, remove the tube seal, drop the tube into the fuel tank, pump, pump, pump, however many squirts you needed, lock the pump down at the end of the last pump, replace the tube seal, pump gas, go to the other wing, repeat, set the jug back into your carrying receptacle, go fly!

 

It might be a good idea to have the tube sealing cap permanently attached to the end of the tube so that even I could not accidently drop it into the fuel tank!  Or I guess you could have a small catch bottle attached to the side of the jug to insert the end of the tube into when not in use and not have a sealing cap for the tube.
