Hello. Just got back from my first visit ever to a Bass Pro Shop and I'm still in awe. Simply fantastic. The official opening is next week. They only seemed to have one kind of two stroke oil which was Penzoil Synthetic Blend. Can anyone tell me if a synthetic blend is a blend of synthetics or is it a blend of synthetic and normal oil. It was not very expensive if that is a clue. As always, I appreciate your response. Rick.
