How to prepare a fuel-oil mixture, 25:1, 30:1, 40:1

For combustion tools, we often need a fuel-oil mixture. In my video, I show how to prepare a fuel-oil mixture with a ratio of 25:1. A 30:1 and 40:1 mixture can also be obtained by the same method. I use unleaded 95 gasoline and oil for two-stroke engines to make the mixture.
