Do fuel system cleaners actually work? Testing Gumout "All-in-One"

Опубликовано 12 декабря 2014, 4:43

This is the first test in a series of fuel cleaner test I will be performing to see how fuel cleaners work and if they actually work. In this video I tested Gumout "All in one" fuel system cleaner. I use a mini borescope camera to look into the engine and see how dirty the engine is before the fuel treatment and then after the fuel treatment.
I followed the instructions on the container and Gumout fuel cleaner did a great job cleaning the shiny, sludge buildup, but did not work as well as I would have thought on the clumps of hard carbon buildup. It did not clean the cylinders as much as I thought it would since they do say one bottle will clean the engine.

Here is the fuel cleaner I used: amazon.com/gp/product/B004AYTR...
