BOOSTane Premium is formulated to increase octane levels up to 100. BOOSTane Premium is there for your peace of mind. With engines getting more and more horsepower out of smaller and smaller engines, we are becoming increasingly susceptible to the harmful side effects of poor or inadequate fuel quality. Whether you are in an area that only has low grade fuel, or you have a vehicle that is susceptible to the harmful side effects of ethanol supplementation (E10), there needs to be a solution. BOOSTane Premium is just that.
