FYI, you can drive right up to the AVGAS pumps at Limon airport. All you need is a credit card. The airport is open (Self-Service) and no FBO around.

As far as the winter pump gas goes, you'll see a drop in mileage due to the ethanol/gas mix. Most problems seem to occur in the spring time when the weather starts to warm up in the '70's and cars are still using winter gas. No noticeable problem with my Cobra the past two months but it's EFI.
