Can I use 2-cycle engine oil in a 2-stroke engine without causing problems?

Answer 1

2 cycle and 2 stroke mean the same thing. It is 2 cycle oil. Yes is the short answer. There is a difference between oil for an air cooled engine and a water cooled engine. Read the label and get the one that is right for your engine.

Answer 2

2 cycle and 2 stroke are the same thing. You just need to make sure you get the right ratio. As for a different oil for air vs liquid cooled engine I don't think there is a difference.
