When referring to fuel treatments, I tend to stay away from them unless necessary. There are a few exceptions and I explain those in this video. I will remind everyone most engine manufacturers do not recommend fuel additives and some advise against using them for one reason or another.
The algaecide treats the fuel for algae, not for performance, unlike most other treatments. I use this once a year unless I have an algae problem, then until the algae is gone.
Enjoy the video, be safe out there!
