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.

It performs.
Best cleaner I’ve used. When rebuilding carbs years ago, cleaned out anything I used it on. Now with fuel injection, ports are even smaller and still does an excellent job. Have been using this product for decades, only choice in my book!

Effective Fuel System Cleaner – Great Value for a 6-Pack!
The Gumout Fuel System Cleaner is fantastic! I’ve used it in my car, and it really made a noticeable difference in engine performance. The cleaner helps reduce engine knocking and improves fuel efficiency. It’s easy to use and the 6-pack offers great value, ensuring I always have some on hand for regular maintenance. Definitely a must-have for anyone looking to keep their vehicle running smoothly. Highly recommend!

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.

Great help in maintenance of an old system.
Did a great job on a 35 year old injection system, got it sounding good and restored quite a bit of the fuel mileage percentage.

Great product! Helped clean injectors
Helped with check engine light due to system too lean. Helped clean injectors. With a little driving around check engine light went away without having to clear the code. Definitely recommend. I use one bottle timed with every oil change

I change my oil every 3000 miles except for the Porsche.
All three of my cars are over 50,000 miles my cars are 2016 GMC 2017 Porsche Cayenne, and a 2021 Ford Explorer. So far it’s really worked well with all my vehicles plus I maintain everything very well but every time I do an oil change, I stick a bottle of this in my tank and I do it when the tank is done at almost empty hope this was helpful.Have a great day
