I frequently use fuel stabilizer in my lawn tractors when storing them over winter, and have found it actually fairly effective. I have also remarked that I am able to store gas much longer and have it usable in string trimmers, lawn mowers, etc. if I have stored it with a fuel stabilizer in it.

However, I fail to see how fuel stabilizer actually works. I understand that it prevents moisture content increases, and prevents the evaporation of the volatile components of gas? Is this the case, and if so, how does that actually work?

The fuel stabilizer actually separates from the gasoline after you let it sit for a while and forms a film on top separating the air from the gas, preventing the gas from oxidizing and picking up moisture from the air.

  • Huh, fascinating, and welcome to mechanics.stackexchange.com! Do you have any references you could link to? – anonymous2 Jul 21 '17 at 9:40
