Our Fuel

We exclusively pump Mid-Grade Gasoline treated with ValvTect Marine Additive. Regular pump gas isn't formulated for the harsh marine environment, which is why our fuel is specially engineered to protect your engine.Why ValvTect Matters for Your Boat:Prevents Phase Separation: Marine environments are high-moisture. ValvTect keeps moisture suspended safely in the fuel to prevent engine stalling and fuel system failure.Cleans & Protects: It actively cleans internal engine parts and fuel injectors, maximizing your fuel economy and horsepower.Extends Fuel Life: It stabilizes fuel for up to a year, preventing harmful sludge and varnish from forming during periods of inactivity or winter storage.Clean fuel means a reliable engine. Pull up to the dock and fill up with confidence knowing your boat is getting the protection it needs for the open water.
