Just and FYI on a new product that came out earlier this year. Product's main focus is to eliminate problems caused by ethanol in today's fuels(if you're lucky enough for that to be your only option).
It also serves as a cleaner and short term stabilizer. More info here:

Give me a shout if interested in pricing.
