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. Yvon Cournoyer.
