How fuel stabilizer helps:
* Slows down oxidation: Gas breaks down over time, forming gums and varnishes. Stabilizer slows this process, preventing these harmful deposits from forming.
* Maintains fuel volatility: Old gas can lose its ability to evaporate properly, leading to poor combustion and engine issues. Stabilizer helps preserve the gas's volatility.
Limitations:
* Can't fix severely aged gas: If the gas is extremely old (think years, not months), it might be too far gone for stabilizer to fully salvage.
* Doesn't address all issues: While stabilizer can help prevent gum and varnish, it doesn't eliminate other issues like water contamination or phase separation.
* Doesn't improve performance: Stabilizer prevents degradation but doesn't improve the gas's quality beyond its original state.
The Bottom Line:
* If your small engine fuel is a few months old and you're concerned, adding stabilizer is a good idea.
* If the fuel is significantly older (over a year), it's probably best to drain it and use fresh gas.
* Always refer to your engine's manual for specific recommendations on fuel storage and stabilizer use.
In addition to fuel stabilizer, consider these factors:
* Fuel quality: Use high-quality, ethanol-free gas whenever possible, especially for storage.
* Storage conditions: Store gas in sealed containers in a cool, dark place.
* Regular maintenance: Regularly cleaning your small engine's fuel system can help prevent issues related to old gas.
