The weather has changed today so many people will soon be spending their weekends preparing their boat for Winter. Once everything is ship shape inside (use Exit Grease for the galley and any oily spills around the engine), don't forget to take care of your fuel tank.

Simply double dose with Fuel Set FCC and add fuel to the top of the tank when laying up your boat for the Winter.
