KATHMANDU; The US Environmental Protection Agency (EPA) has approved the temporary nationwide sale of E15 fuel. The move aims to ease rising fuel prices and increase supply.
The waiver allows E15 sales from May 1 to May 20, 2026. Officials may extend the period if market pressure continues.
E15 is a gasoline blend with 15% ethanol. It is commonly sold as “Unleaded 88.” It is cheaper than regular fuel but offers slightly lower fuel economy due to lower energy content.
Most cars made after the early 2000s can run on E15 without issues. However, older vehicles may face long-term damage. Ethanol can affect rubber and plastic components in older fuel systems.
Small engines in motorcycles, boats, and lawn equipment are not recommended to use E15. These engines are more sensitive to ethanol blends.
Ethanol also absorbs moisture from the air. This can lead to fuel separation if stored for a long time. As a result, E15 has a shorter shelf life.
Fuel pumps may not always clearly label E15. Some stations display only the octane rating. Drivers are advised to check vehicle manuals before use.
The waiver also removes summer restrictions linked to smog concerns. This allows wider availability of E15 for a limited time.
The policy comes as average fuel prices in the US cross $4 per gallon. Ethanol is cheaper than gasoline, but higher production may impact corn supply and related markets.
The US imports less than 10% of its oil from the Middle East. The decision supports domestic energy use and aims to reduce fuel costs for consumers.
