Portable fuel tanks can store fuel for extended periods, but several critical factors influence fuel stability and tank integrity:
- Fuel Type: Gasoline contains volatile components that degrade through oxidation when exposed to air, forming gums and varnishes. Diesel is more stable but susceptible to microbial growth if moisture is present.
- Tank Material: High-quality, fuel-resistant materials are essential. Metal tanks resist oxygen and moisture but can corrode. Plastic tanks offer chemical resistance but may degrade from sunlight or physical damage.
- Storage Conditions: Store in a cool, dry, dark place. Heat accelerates fuel degradation, sunlight causes chemical changes, and moisture promotes rust and microbial growth.
- Proper Sealing: Well-sealed tanks prevent air entry, reducing oxidation and evaporation. Fill tanks completely before storage to minimize air space.
- Fuel Quality Assessment: Inspect for cloudiness, discoloration, or unpleasant odors which indicate degradation. Stabilizers can extend fuel life but don't replace proper storage practices.
Successful long-term fuel storage in portable tanks requires careful attention to fuel type, tank material, storage conditions, and proper sealing techniques.
