Yessir. Your engine gets the most power and best efficiency with the lowest octane fuel that it can run without detonation, indicated by "ping" under heavy load. If it's a stick, put it in high gear at a moderate low speed, floor it and if it does not clatter on regular gas then any higer octane rating is just being wasted, and will actually run less efficiently.
