Supreme Fuel Injector Cleaner + Octane Booster
The compromise is now over, with Gumout® Supreme Fuel Injector Cleaner + Octane booster you no longer have to choose between clean fuel injectors or octane boosting performance – you can have both! Over time carbon buildup can clog fuel injectors and intake valves robbing engines of fuel economy and performance while also increasing exhaust emissions. Gumout® Supreme Fuel Injector Cleaner keeps carbon deposits from forming on critical engine parts maintaining performance and fuel economy. Made with genuine MMT octane booster Gumout® Supreme Fuel Injector Cleaner also increases the fuel’s octane rating to ensure proper combustion, smoothing rough running engines, stopping knocks & pings, maximizing horsepower, while improving acceleration and throttle response.

I have never tried this brand cleaner before and I was impressed with it. My car was running fine but being a 25 year old car, it ran smoother and had more power almost immediately.

Clean car
My 2015 Mazda 3 lost it's zoom zoom, it was acting very sluggish and unresponsive this product put the zoom back in the zoom zoom. You clean the inside of your car, clean the inside of your fuel system.
