We used to only talk about fuel treatments for long-term storage, but with the advent of ethanol-laced fuel, we need to modify our recommendation to include bikes that aren’t ridden on a regular basis – particularly those that reside in a humid environment. Ethanol has a taste for water – which wouldn’t be a problem if it didn’t precipitate out of the fuel mixture when it had quenched its thirst. Yep, once ethanol has absorbed the most water it is capable of holding, it can turn into goo that settles in the bottom of your tank. Here is where fuel additives, like Sea Foam, are important. Add the treatment and go for a nice, long, tank-draining ride every now and then, and you’ll keep your fuel filter and injectors happy.
