Instant Improvement

★★★★★

I bought this at a gas station when I filled my tank expecting better gas mileage since my 04 explorer has 210k miles on it, I bought the cheapest injector cleaner cause I've usually bought Lucas and didn't see any difference in past vehicles. As soon as I left the gas station my truck quit having what I thought was transmission problems. It is shifting smooth instantly & not driving as rough as it had been for the past week. I will continue this treatment monthly as I drive 500 miles a week for work.

Magical results

I'm from Pakistan and I have a Suzuki Japanese car 800 CC which I bought in 2010. It has done 90000 KM. Since last many months I was experiencing rough idling, hesitation and engine auto ignition after the car is being switched Off. I did several tune ups of engine but problem remained the same. Recently, I used Gumout complete fuel system cleaner and I was totally amazed about the positive results this product delivered in few days. Just after half tank usage there is a significant overall improvement. Almost all problems has eliminated. Will use another bottle of this product for cleaning the last remaining deposits in fuel system. I'm very impressed & strongly recommend others to use this magical product.

Easy to use - modest quantity gets the job done !

I have used this product for many years and always keep a couple of cans on the shelf in my shop. I restore antique cars and often find the need to clean old carburetors - as well as those of friends who have not maintained their old cars. I also have friends who will come by to "borrow" my carb cleaner....BECAUSE IT WORKS !!!

GUMOUT HAS ALWAYS BEEN ONE OF MY FAVORITE PRODUCTS

the fuel injector cleaner really does really work you don't have to be skeptical about this stuff definitely worth the money. Don't bother with gumout or the watered down versons of this stuff you can get at at Walmart if you want results on one bottle this is the stuff.
