It works on all fuel systems.
I found a video by Scotty Kilmer, a popular YouTube automotive expert, where he tested this product on a car to see how well it works. In the video, he used a borescope to check the engine’s cylinders before and after running two full tanks of fuel treated with the product. The results were impressive: the cylinders looked much cleaner after using the additive, with clear reductions in carbon deposits and dirt. Scotty pointed out that this was an independent test, done without any sponsorship or outside influence, which meant the results were fair. Based on his findings and the manufacturer’s directions, I chose to use the product as instructed, adding it to my fuel tank to keep my engine running well and clean. The simple application and noticeable results make it a great addition to my vehicle maintenance routine, especially for keeping the fuel system and cylinders in good shape. I use it every 2 months (approx 3-4k miles) and my acceration and idle are like it came out of the factory.

Muy buen producto
Recien lo use en dos vehiculos, un Hyundai que habia tenido problemas en su ECU y un Rogue que tenia un fallocito leve. En ambos casos despues de un par de dias de uso las fallas desaparecieron, evidentemente era sucio en el sistema de combustion

Solid Product for Routine Maintenance
Used one bottle during a fill-up and noticed slightly smoother engine performance. It’s hard to measure long-term effects, but for the price and quantity, it’s a great value. Easy to use and well-packaged. I’ll continue using it as part of my regular maintenance routine. One star off just because results aren’t dramatic.

Works great; difference was immediately noticeable.
Why did you pick this product vs others?:I've had great luck with Gumout Multi-system Tune-up, so I figured I'd also give this a try. It seems to work just as well. The difference before/after is not subtle. The engine seemed to pull effortlessly and very smoothly. Much more low end torque. And this was on 87 octane. I made sure total gas in the tank was about 15 gallons, so, somewhat below the maximum Gumout suggests, i.e. a concentration somewhat on the high side. Very very impressed. Will definitely buy again.

Helped Engine Performance
My engine (2013 6-cylinder Mazda) appeared to gain better performance as I used it.
