I use Fuel Power 60, and I was lucky enough to get some Fuel Power 3000 lately. Not only is it a cleaner, but, it allows me to run 89 octane without pinging, in a bike that is spec'd for high Octane....and it WILL ping on 91 Octane or less without Fuel Power in the tank. I have used Seafoam in cases where the bike was used (and it worked well), as it is a much more powerful (harsh) cleaner than FP 60.
