Damn those advertisments, they got me thinking about my MR2 sitting in the gargage and both Lori's and my bike sitting next to it... Should I really be concerned about using this product if I go out and start the motor's every week or so? Is this nessesary for the winter, and what do you do once you start them up again? i.e. do I need to drain the tank or just start it up and run out the old gas? Probably all stupid questions as I should know all these answers but I have never worried about it before. Curse you advertisment people!
