Hi Yvon,
My interpretation would be the 25 to 40 ml increase represents 15 ml of
alcohol. That would represent 15 ml alcohol / 200 ml fuel + alcohol = 7.5 % I've never actually done one of these tests, so if I've got it wrong
let me know. :)

Yesterday I went to the Sorel airport and tested the fuel in my Zenith 90 liters tank.
This fuel already contains two stroke oil in the ratio of 1:130 per volume.
In a cylindrical ungraduated container I poured 25 ml of tap water and added 200 ml of fuel
After 1 hour and several vigourous shakings I observed an increase in the volume of water to 40 ml
The increase is about 4% (?)
All quantities are approximate.
Since I began running and flying my 1986 Mazda 13B engine, I have tested in flight all grades of mogas and also 100LL avgas. I would wait until my fuel level was very low and would fill my tank with the différent grade. Never detected a change in the performance of my engine. The only times I drew water from my fuel tank was when it was filled with 100LL avgas.
