Whether your boat is equipped with a gasoline or diesel motor, fuel issues may occur. You may have trouble starting the engine, experience unstable idle or poor performance, and these problems may actually occur even if you use quality fuel. The point is, the quality of this liquid may deteriorate if you haven't used a boat for several months. Besides, some boat engines may have trouble caused by ethanol or water in hydrocarbons, along with some other issues. Marine fuel additives are meant to address most of them, and there are special fluids for gasoline and diesel.

The action of these products is quite complex. Some of them are meant to stabilize fuel or rejuvenate hydrocarbons remaining from the past season, others clean the fuel system and combustion chamber from various sediments and carbon, still others prevent problems related to ethanol or water, protect the system from corrosion, etc. Most additives combine several functions and can be a nice solution for regular use. In our online store, you can choose from a wide range of additives meant to keep the vessel's engine and fuel system in top shape.
