Being a beginner at this hobby, I ask the question. What is the difference between 2 cycle and 4 cycle fuel. I was told that 4 cycle has more oil in it. And that I could burn it in a 2 cycle engine. I then ask, what would be the benefit of using 4 cycle fuel in a 2 cycle engine. The answer was more compression and a cooler running engine. So this is what created my original question.
