No. Octane booster is simply additives to gasoline that increases the liquid's tolerance for compression. For instance, if you put 87 gas in a engine that's designed for 93, chances are you're going to start hearing a knocking sound or pinging sound. That sound is from the air/fuel mixture prematurely igniting simply due to the pressure created from the piston compressing in the cylinder. Premium fuel, or fuel with a higher octane rating, enables the vapor mixture to withstand this higher compression until the piston is at the top of the stroke and the sparkplug ignites, setting off the mixture as it's supposed to. Octane booster does fuck-all to increase engine performance using regular gas in a regular gas designed engine, nor does it increase performance in premium gas engines using premium gas to begin with. Also, the cost of the octane booster is more than if you would have just bought premium gas to begin with. It also would do absolutely nothing to change the fact that you're running 15% of corn ethanol through your engine, and neither would fuel stabilizers.
