Why Fuel Care is Important

Even more than the gas in your car, the gas in your boat needs special care to keep your engine running at peak performance. Gasoline begins to go bad within about two weeks. When left untreated, some of the fuel components begin to oxidize and form a gum-like substance. The substance settles in fuel lines and tanks, carburetors and injectors. When you try to burn this fuel, deposits can form in the combustion chamber. Over time, these deposits build up and reduce your engine’s performance.

Fuel additives keep your fuel optimized, protect your fuel system, and remove any leftover deposits. With the Mercury Fuel Care System, you can trust that you’re using products that are specially formulated – by your engine’s manufacturer – to help you get the most from your Mercury engine.

The Mercury Fuel Care System is the first line of defense against fuel-related problems. However, Mercury also recommends the following precautions to protect your engine:

  • Buy gas from known and trusted sources whenever possible.
  • Keep your gas tanks clean and check them periodically for water and sediment.
  • Check your fuel filter often. Fuel filters help prevent fuel contaminants from entering your engine. Under certain conditions it is possible for filters to suddenly become clogged, so always keep an extra filter on board should it need immediate replacement.
