About Fuel & Additives
What are fuel additives & engine treatments?
One of the biggest problems with boating fuel and the need for engine treatments are interactions with polymer components in the boat's fuel system and water issues.Being out on the water all day gives your boat excessive exposure to water, and that will play havoc with many of your systems.
Water helps facilitate corrosion, as well as the physical properties of water means that with excessive heat and cold, water can expand and get into all sorts of nooks and crannies of your motors and mechanical parts.
Engine treatments are an important part of eliminating this with proper lubrication, fuel stabilization, and winterization are a must for marine engines.
Otherwise, over time, water can begin to promote oxidation and even pitting throughout your engines.
Organic material might also propagate, which can cause blockages, as well as bad fuel which will ruin your engines.
Fuel additives are extremely effective at solving these problems.
Which is why Defender offers a wide variety of marine-specific additives to keep your boat running smoothly.
