Winterizing Your Boat Fuel System – Tips & Condolences

Serious boaters know that proper care and maintenance of their rigs are the cornerstones of trouble-free boating.   Whether you are an avid angler, watersports enthusiast or family cruiser, you want your boat to start up easily, run great and get great fuel efficiency every time you venture out on the water.

Taking care of your boat is even more important when you’re storing it for an extended period of time.   This holds true whether you’re storing your rig for the offseason or just not going to be using it for a while.

The first and most important step is to use a high-performance fuel additive to stabilize your fuel and protect the entire fuel system from the build-up of gum, varnish, and corrosion over time.    Techron Marine Fuel System Treatment was scientifically formulated by the fuel experts at Chevron to provide the highest level of protection during extended storage, while also fighting the corrosive effects of the harsh marine environment.

Gum can form in fuel systems and clog the works when fuel gets old.

Ethanol Issues

More than 98% of gasoline sold in the United States contains ethanol, which attracts water into your boat’s fuel system.  During offseason storage — or any period of infrequent operation — this water accelerates fuel oxidation, the formation of gum and varnish and can lead to corrosion in the fuel system.  It left too long, this corrosion, varnish, and gum can cause permanent damage to your boat’s fuel system.

Some boaters attempt to prevent this by draining their fuel system in preparation for storage.    This is often impractical, and it also wastes money and gasoline.  Most importantly, it can actually create problems.  Draining the tank exposes the metal components inside to condensation, which may accelerate fuel system corrosion.  It can also cause internal components in your fuel system to dry and crack over time, leading to potential hazards and leaks.

In addition, there will usually be some fuel left in the tank after draining, and it will be subject to oxidation.  This can create gum and varnish that can restrict fuel injectors, gum up carburetors, and even clog the system badly enough to cause a fuel pump failure.

Fuel system leaks and clogs can arise from fuel systems that are not stored properly.

Stabilize A Full Tank

Instead of draining the tank, add Techron Marine to a nearly empty fuel tank and then fill it up nearly to the top with quality gasoline.  Leave just a little room for expansion.  Then, run the engine for a few minutes to allow the treatment to circulate throughout the system.    It only takes one ounce of Techron Marine to treat 10 gallons of fuel, so follow instructions and make sure you are dosing the fuel properly.

Techron Marine has been scientifically engineered to keep fuel fresh for up to 24 months.    Head-to-head laboratory tests have shown that Techron is also a top performer when it comes to engine and fuel system cleaning and corrosion protection in the harshest environments — especially in saltwater.  Because of this, Techron Marine is an ideal additive for use with every fill-up, not just during storage.  Used regularly, Techron Marine can help keep a boat’s fuel system and engine running clean, strong and at peak efficiency.     It works in all types of gasoline-powered boats including two-stroke, four-stroke, carbureted, port- or electronic fuel-injected and direct-injected engines.

This versatility to stabilize fuel for extended storage and also protect boat fuel systems all season long contributed to Techron Marine winning a 2019 Top Product Award from leading trade journal Boating Industry magazine.
