How Plastic Can Contaminate Gas:
* Leaking Additives: Some plastics contain additives that can leach into the gasoline over time. These additives can affect the fuel's performance, causing problems like engine knocking, stalling, or decreased fuel efficiency.
* Vapor Permeation: Some plastics are more permeable to gasoline vapors than others. This means that gasoline vapor can escape from the can, potentially leading to a loss of fuel and potential safety hazards.
* Static Electricity: Filling a gas can can generate static electricity, which can cause sparks and potentially ignite gasoline vapors. This is a serious safety concern.
* UV Degradation: Exposure to sunlight (ultraviolet radiation) can degrade some plastics, potentially causing them to break down and contaminate the gasoline.
Important Considerations:
* Type of Plastic: Not all plastics are created equal. Some plastics are specifically designed for fuel storage and are less likely to contaminate gasoline. Look for gas cans made from HDPE (high-density polyethylene) or other materials designed for fuel storage.
* Age and Condition: Older or damaged gas cans are more likely to leak additives or allow permeation. Inspect your gas can regularly for cracks, leaks, or discoloration.
* Storage: Storing gas in a hot environment can accelerate the breakdown of plastic and increase the risk of contamination.
Recommendations:
* Use Approved Cans: Use only gas cans that are certified by the National Fire Protection Association (NFPA) or meet the requirements of the U.S. Department of Transportation (DOT).
* Inspect Regularly: Check your gas can for any damage or signs of wear before each use.
* Store Properly: Store your gas can in a cool, dry, and well-ventilated area, away from direct sunlight.
* Consider Alternatives: For long-term storage, metal gas cans are generally considered safer and less prone to contamination.
In Summary: While not all plastic gas cans will contaminate your gas, it's essential to use approved cans and follow proper handling and storage practices to minimize the risk. If you have concerns about the safety of your gas can, consult with a qualified professional.
