I have been using 104 Octane Boost in all of my vehicles for years. It works great! Proven horsepower gains for sure!

I have tried a few octane boost formulations and I have found that 104+ is the first one to show actual physical gains that make a real difference on the road and on the dyno. For the price, even if you never get to test on a dyno, you will notice a huge difference in throttle response and acceleration once the bottle is fully mixed in the tank and running thought the fuel system. Now this is not for flex fuel vehicles, but does make a huge difference in Turbo powered V6 engines and V8 engines, you will be pleasantly surprised.
