Thanks, I hardly even venture down there.

Higher octane fuel carries more BTUs, so it will be little better, but still elaborate air cooled lawnmower engine and they run just find on 87 octane especially fuel injected engines.

If you are a full time resident and drive your cart just about every day, any gas will do. If you are a part time resident and your cart will sit for extended periods of time not being driven, absolutely go with ethanol free gas. The very small extra cost of the gas will be well worth it in the long run. Every time I drive my truck to Florida I bring 15 gallons of ethanol free gas back up north, which I can't easily buy up north, for all my seasonal small engine equipment.
