Basics

This page aims to go over the concept of “Fuel Stabalizers”, how they work, and inter-link with related subjects

Industry Standards

Red “Storage” Solution
- A Home Depot Listing for this Product ( ‘’’~8 USD for 236ml As of This Edit’’’ )
  - ( User: Eric here) Need to ask the Outboard Engine mechanic next time they are in town, but they use this stuff
Composition?
- Safety Data Sheets :
  - 2023 SDS
    - 95% Distillates (petroleum) , hydrotreated light
    - 5% Phenol, isopropylated
      - CAS Number : 90480-88-9

This has the added properties of a Fuel Injector Cleaner and Phase Separation Prevention (for better or for worse)
The Latter is largely irrelevant if using Ethanol Free Gasoline or Butanol etc
The Former (Probably) Can’t hurt, but is largely irrelevant if using TopTier Gasoline / Adding in your own Fuel Detergency Additives + Doing Regular Inspections/Maintenance
The Cost/Benefit ratio of that is debatable
An alternative Antioxidant is used, independent testing of this on an ingredient vs ingredient vs control test may be worthwhile
Composition:
- Safety Data Sheets
  - A 2019 Safety Data Sheet for K100G+
    - ”Ethylene Glycol Monobutyl Ether CAS Number 111-76-2, 30-45%”
    - ”n-Butyl Alcohol, CAS Number 71-36-3, 30-40%”
    - ”Primary Alkyl Alcohol, Proprietary, 15-20%
    - Cyclic Secondary Amine, Proprietary, 5-10%
    - Alkenoic Acid, Proprietary, 3-7%

More irrelevant due to Evaporation and Phase Separation being non-issues/diesel engines being less “picky” on fuels
Sludge Formation may be another oxidation issue, and thus short of ultra-refined fuels such as JP-5 / JP-8 etc, or Synthetic Fuels such as OMEx an Additive Package may be worthwhile

Shelf Life
- Ie it is an “Anti-Oxidant”, but will that ability gradually be diminished by Atmospheric Oxygen (especially in an opened but not fully used bottle) and/or from diffusion of atmospheric oxygen or water through the plastic bottle and/or from Storage Temperature (Swings) and/or from UV etc
- May be able to test this via Titration
- IF it happens, quantifying this behavior+predicting it could allow for evidence based “shelf life”, means to reduce it’s occurrence (Amber Bottles, Stable Temps, maybe even purge with CO2 or Nitrogen/Argon etc
Impact on Fuel Quality when the Issues of Long Term Fuel Storage are Removed
- IE can you “over dose” it and/or will it make the Engine Behave Differently (especially at higher doses) compared to “regular” Ethanol Free Gasoline etc)
- When not mixing into a Safety Can, but guessing what the volume of a small engine’s integrated tank is etc is when Over-Dosing is likely
Dry Empty Storage vs Full of Stabilized Gasoline Storage
Performance of the Diesel Version

A Video by the YouTube Channel “FortNine” Titled “Can Fuel Stabilizer Kill Your Motorcycle?” ( ‘’’~9 Minute Watch’’’ )
- While a bit stylized, this video does go over some of the myths on how they work, mentions their actual mechanism of action, and does SOME testing
  - Larger Sample Size / some experimental design aspects may be worth revisiting, but this is a free YouTube video after all!
A Video by the YouTube Channel “Project Farm” Titled “After 5 Years, I Found the Only Fuel Stabilizer that Works! ( ‘’’~14 Minute Watch’’’ )
- The Segment on Fuel Stabilizer is 14 minutes long, there is an additional section on headlight restoration which is irrelevant for this page
