104+ was made for powerful, muscle-bound, high-performance engines that need to scream at the top of their lungs, so to speak. Because 104+ octane boosters are not for those red-blooded American muscle and collector car owners who kid around. It’s made for those who demand the maximum performance out of their engines, like you. And for you, only 104+ will do. 104+ allows your muscle car to run at peak performance for longer-that’s a fact. But don’t forget that it helps protect your engine as well. Reducing knocks, pings and hesitation, it also helps improve fuel mileage and acceleration while cleaning your fuel system at the same time. 104+ Octane Boost. America’s first. And still the best.
