Fuel Stabilizers, Fuel Additives, and Fuel Cleaners - Resources & Information

Marine fuel additives are chemical compounds that are added to marine fuels (such as gasoline or diesel) in order to improve the performance, efficiency, and/or lifespan of marine engines and other fuel-burning equipment. There are many different types of marine fuel additives available, each with its own set of specific benefits and intended uses.

PartsVu offers a complete selection of Fuel Stabilizers, Fuel Additives, & Fuel Cleaners  from OEM manufacturers and trusted aftermarket suppliers. Whether you need a 2 stroke fuel system cleaner, diesel fuel antifreeze additive, fuel cleaner mulitpacks, and more, PartsVu has what you need to get the job done. 

Need help servicing your outboard engine? PartsVu regularly publishes helpful how-to guides and other valuable maintenance information to help boaters service their outboard engines. Browse the PartsVu Xchange, our outboard maintenance blog, for a wide range of relevant topics and review the FAQ section below, covering everything you need to know about maintaining your boat in confidence.

Fuel Stabilizers - Fuel Additives - Fuel Cleaners FAQ

What should I know about Fuel Stabilizers, Fuel Additives, and Fuel Cleaners?

Some of the most common types of marine fuel additives include:

  • Detergents: These additives help to clean and maintain the fuel system by removing deposits and other contaminants that can build up over time.
  • Stabilizers: These additives help to keep fuels fresh and prevent degradation over time, which can help to extend the shelf life of stored fuels.
  • Lubricants: Some marine fuel additives contain lubricants that can help to protect and extend the life of fuel pumps, injectors, and other fuel system components.
  • Corrosion inhibitors: These additives help to prevent corrosion in fuel tanks and other fuel system components, which can help to extend the life of these components.
  • Octane boosters: These additives can help to increase the octane rating of fuels, which can help to improve the performance and efficiency of engines.

Overall, marine fuel additives can be used to improve the performance, efficiency, and lifespan of marine engines and other fuel-burning equipment. It is important to choose the right type of marine fuel additive for your specific needs and to follow the manufacturer's instructions for use.

How much stabilizer per gallon of gas?

The amount of boat fuel stabilizer that needs to be added to each gallon of marine fuel varies based on the formulation of the product. For instance, Star Tron Stabilizer+ Fuel Storage 1 oz. treats 5 gallons, whereas Yamaha Fuel Stabilizer and Conditioner Plus requires 1 oz. for 3 gallons (and for storage over 2 months, it requires 1 oz. to every 1 gallon of fresh gasoline.).

How long can you store gas with stabilizer?

To answer how long can gas be stored with stabilizer, the truth is that it depends. Here’s why:

First, the length of time that marine fuel (such as gasoline or diesel) can be stored with fuel stabilizer for boats will depend on a variety of factors, including the type of fuel and the specific fuel stabilizer being used. In general, fuel stabilizers can help to extend the shelf life of stored fuels by preventing degradation over time. However, the exact amount of time that fuel can be stored will depend on the specific formulation of the fuel stabilizer and other factors. For example, Stabil Fuel Stabiliser guarantees fuel storage up to 24 months

As a general rule, it is generally recommended to use marine fuel within a few months of purchase to ensure optimal performance and prevent degradation. Fuel stabilizers can help to extend the shelf life of fuel beyond this time frame, but the exact length of time will depend on the specific product being used and the storage conditions. It is important to follow the manufacturer's instructions for use and storage of fuel stabilizers and stored fuels to ensure optimal performance and to prevent problems such as engine damage or reduced efficiency.

How long is gasoline stable?

Gasoline is generally stable for three to six months, while diesel fuel can last up to a year before it begins to degrade. However, fuels with high ethanol conten can lose combustibility in just one to three months due to oxidation and evaporation.

What’s the best fuel treatment for water in gas?

There are several fuel treatments available that are designed to help remove water from gasoline and prevent water contamination in fuel systems. These fuel treatments can be particularly useful for marine engines that may be exposed to water or humid environments. Some common fuel treatments for water in gasoline include:

  • Fuel drying agents: These additives are designed to absorb water from gasoline and help to prevent water contamination in fuel systems. Fuel drying agents can be particularly effective at removing small amounts of water from gasoline and preventing further water contamination.
  • Fuel stabilizers: Fuel stabilizers can help to prevent fuel degradation over time and can also help to absorb small amounts of water from gasoline. Fuel stabilizers are typically added to fuel before storage to help extend the shelf life of the fuel and prevent problems such as water contamination.
  • Fuel system cleaners: These additives are designed to clean and maintain fuel systems by removing deposits and other contaminants that can build up over time. Fuel system cleaners may also help to remove small amounts of water from gasoline and prevent water contamination.

Can you use too much diesel additive?

It is possible to use too much diesel additive in marine engines, and doing so can potentially cause problems.
