I thought that conditioner was only for use if you stored the fuel for a lenth of time, to keep moisture out. if you are runing alot of fuel through both the motor and burner you should not have to worry about it. if you are haveing problems (other than reading my spelling) and use at least one tank every day or so you might want to look at other things. if so you can e-mail me with it and i will help figure out whats going on.
