Difference of gas at land pump and gas at marina pump?

I never heard of that but thank you for the tip! It sounds like you have years of good outcomes using the product. They sell it at Walmart too. You cant beat that at all.

No problem. And if you're in doubt it's always better to put too much in than not enough (like maybe at the end of the season and you have a partial tank). Supposedly over dosing this stuff will cause no harm so long as you don't get too carried away. If you want an even better deal buy the 16:1 concentration formula on Amazon in a larger bottle...that's usually what I do.
