How do I add gas and oil to a gas can half-filled with 50:1 mixture so
that it stays 50:1?

For example: *I have a 10 gallon can on my boat filled a little more
than half way with of 50:1 mix. *I can't tell exactly how much 50:1
mix is in the can. *I am at a gas station and want to top off the can
and yet keep the mix at 50:1. *How would you do this?

Here are some possibilities I can see:

1. Put in a known quantity of gas that stops short of filling up the
tank. *Calculate how much oil is needed for that known quantity of
gas. *Add the oil, shake the can. *Accept how much empty space there
is at the top of the can.

2. Fill up a another can with maybe 6 gallons of gas and add the
correct amount of oil (5/8 of a cup,.. or 10 tablespoons maybe).
Shake up the can and pour it into the 10-gallon can.

Any ideas?

Thanks
