Run it in several vehicles from street cars to race cars. Started using it when I had some left over from my Lycoming powered airboat. Many race gas manufactures use or used it as the base for the fuels they sell. My airport only allows me to carry fuel jugs into the pump and carry them out so I don't usually buy more then 15 gallons at a time. The pump is a just a self service credit card type pump. I even run my small engines on it before I park them for seasonal storage. Remember it is leaded fuel and will effect oxygen sensors if you are using them.
