Not if you don’t have a good reason to do so. Adding chemistry to the fuel does not help a properly functioning engine.

If you want a really good useful answer, I would suggest telling us why you are asking the question and exactly what specific Gumout product you are referring to, since they may many different products.

I would suggest that the addition of a fuel system cleaner is an OK thing to do as a part of normal maintenance but will not substitute changing fuel filters or normal tuneup time. I use seafoam once a year in the fuel system of my toys and change the filters as recommended by the manufacturer, and have never had a fuel problem. Rocketman
