i use sunoco purple race gas mixed with klotz...smells great and works great...i buy the gas for 4$ a gallon but its good stuff! i use it because race gas is recommended with 17cc domes in a banshee and portwork and everything...in my red banshee i run alcohol but i hated it...u have to clean out the cylinders all the time to keep it from rusting but i only use it once a week or every 2 weeks for racing...the blu shee is for duning...i live in louisiana and if u do to please let me know
