ive used the star tron in both of my boats, it lasts a lot longer.. one ounce will treat 16 gallons, vs stabil which if i remember right 4 ounces treats 16 gallons?
but you deffantly pay for it, which the stuff is slightly more expensive.. i bought a quart of the star tron last summer an still have a pint of it left an i use my boats a lot
