RT,
The best way I have come up with is to buy a bottle of 1. 2 stroke engine oil or 2. a bottle of fuel stabilizer - both of which have a smaller bottle at the neck that allows you to measure out exact oz. amounts.

I stopped at The Container Store the other day and picked
up 4 2oz bottles (square, with leakproof caps). I marked
them at every 1/2 oz with a permanent marker. For a 26
gal tank, that would call for 2.8oz of Primrose 409, but
usually when I fill up I still have 1/4 tank left, so the
filled 2oz bottles should be perfect for 3/4 tank of
fuel. I put the four square bottles in an old 3"
plastic cube (i.e. the ones you buy at the office supply
store for dispensing square pieces of paper), and they
fit perfectly! I put the cube behind the back seats on
the drivers side-- near the fuel cap.
In warmer weather I will use the Primrose 405, which is
less concentrated, calling for 1.6oz for a full tank,
which would be 1.2oz for 3/4 tank-- so I'll just fill
the bottles a little more than 1oz in the summer (half
full).
BTW: I did send email to Primrose, asking if there were
any problems with using the plastic containers (i.e.
they are semitransparent, so issues with light), and they
indicated that there should be no problems...
