it was really made for alcohol burning engines... a drag car on alcohol has a strong smell it burns your eyes if your close enough to the car..or what ever.. the scent helps some..not 100% but much better...but if you cant handle the fumes.. do back to watchin nascar.......ha ha.... topfuel really gets your attention.... this is really what it was made for...but you can run it in what ever.. but $$$
