A StarTron bottle will last for long.
I bought one at my nearby shop with dyno. I have not tried it yet. Bikes gets V-Power with max 5% ethanol, maybe less in reality.
He recommended it for E10 fuels during the winter. He used it for all kind of engines when parked for a longer period.
Lawnmovers, snowmobile, bikes.
Did not cost that much either.
Red Line fuel additive cost much more and last for a few tanks only.
