VP Octanium Unleaded octane booster gives an octane boost of up to 7 numbers (70 points)! Furthermore, it eliminates knocking and pinging, cleans fuel injectors, and knocks out gum and varnish build-up. Compare that to many of the competing brands. Another key point is that some brands dont even specify their actual octane boost number while others only provide a boost up to 3 to 5 numbers.
