That means you need to plan ahead to have it wherever it's going to be shipped. But if you're cruising and not staying at a marina it does require planning. Yes you can always rely on standard gas from a dock in the interim, and as long as you can use it up in a short period of time it's probably not an issue. However if you let that E10 sit in your tank, maybe not so good.

I plan to stay with TruFuel, as it's convenient and my 2.5 HP Suzuki doesn't use much in a season.
