yes as you are premixing it then 2 stroke premix oil is what you should use,it will settle to a certain extent overnight on the tank base but a quick shake in th morning will mix it back up easily,aslo leaving the cableon the pumpis ok but if i were you and it was air colled i would take the pump out and also the oil pump drive belt off the crank shaft if its water cooled leave it on as it also drives the waterpump,
