What Gene said, do not bother to try glow fuel in a gas engine. Also, most of the 2 stroke mixes come in a container that is sized for the size of fuel can you will mix it in - 1, 2, 2.5, or 5 gallon. They also tell you on the side of the container how many ounces per gallon of gas. Put the oil in first, then fill the container, it will mix up when you fill it. Some people will still shake the container after it is full anyway, just to make sure.
