Yes its using petrol unleaded while two stroke using two stroke oil
4 stroke fuel is straight petrol, it does not have oil in it! If you use it in a 2 stroke engine you will seize the motor. 2 stroke fuel has oil added to it.
nothing the 2stroke-petrol will smoke as it burns the oil which should be mixed in it
