I know many people who dip afterwards to stop them smouldering to make the wicks last longer, though personally i feel it won't save you any money as your using up fuel everytime you do this which will probably end up costing just as much asx you will save by making your wicks last that little bit longer.
However if you want to dip afterwards feel free to, I may well be wrong.
