I like to run a small percent of premix, like 100 to 1 in addition to the oil injection. I'm wondering if isopropyl alcohol will seperate the oil. Why I ask is that when I was mixing a 5 gallon jug today, I put the oil in a small clear measuring container and then I put in 3 ounces of isopropyl and it wouldn't mix with the oil. I'm wondering what they do together in the gas tank when mixed with the gasoline. Does anyone know if it is safe to mix the three together?
