Marine Fuel Additives and Treatments


Fisheries Supply carries marine fuel additives, antifreeze, and other essential products to maintain your boat's engine health and reliability. We offer a wide range of products from top brands like Starbrite, Sta-bil, and Stanadyne, ensuring your boat performs optimally in various marine conditions.

Importance of Marine Fuel Additives

Boat fuel additives are multi functional and crucial for enhancing fuel quality and engine performance. They prevent corrosion, reduce buildup, and ensure your engine runs smoothly. Stored fuel can oxidize in the tank, forming sediments from mold and bacteria. A good marine fuel stabilizer helps decompose these sediments before they contaminate your fuel lines and filters.

Types of Marine Fuel Additives


Fuel Stabilizers for Boats

Fuel stabilizers are essential for maintaining fuel quality during storage.

They:
  • Mitigate the harmful effects of ethanol, such as phase separation.
  • Repel water infiltration, protecting metal parts from rust.
  • Limit evaporation.
  • Preserve fuel freshness.

Marine Diesel Fuel Additives

Marine diesel additives improve fuel efficiency and protect against microbial growth.

They:
  • Enhance cetane levels.
  • Provide lubrication.
  • Prevent algae and bacterial growth.

Fuel Treatment for Boats

Marine fuel treatments help with fuel related problems. They also clean and protect the combustion system.

They:
  • Remove carbon deposits.
  • Dissolve gum and varnish buildup.
  • Prevent new deposit formation.

How to Use Marine Fuel Additives

Incorporating fuel additives into your maintenance routine is simple:
  • Follow Manufacturer's Dosage: Each product has a recommended dosage amount. Adhere to these guidelines for optimal results.
  • Regular Use: Add fuel additives every time you refuel to maintain consistent protection and performance.
