Will be taking a boat trip down the river to Charleston Harbor in September. Can someone tell me where to find 93 octane. Ashely Marina and Charleston City Marina do not have it. My research reveals the "Octane Boosters" are a joke. Need some local help.

Thanks in advance.

Try the Isle of Palms Marina I think they have it. I rented a house with a slip at the marina last year. Check out the Morgan Creek Grill, it's right there near the fuel dock. Good eats!!
