E15 fuel is safe for cars from 2001 onwards
E15 fuel, also known as Unleaded 88, contains 15% ethanol and 85% gasoline. Ethanol is a biofuel derived from fermented corn, wheat, grain sorghum, barley, potatoes, sugar cane, or sweet sorghum. It has been added to gasoline in the US fuel supply for decades, mostly at 10% and now at 15%.
The advantages of using E15 fuel include its sustainability and cleaner-burning properties compared to pure petroleum-based fuels. Ethanol burns with almost no visible smoke, reducing carbon emissions and displacing toxic and carcinogenic fuel additives. Additionally, E15 fuel is typically cheaper than regular unleaded gas, with prices up to 10 cents lower per gallon.
While E15 fuel is generally safe for newer vehicles, it is always recommended to check the vehicle's manual for specific fuel requirements. Some newer vehicles may still recommend using a maximum of 10% ethanol, and using E15 fuel may result in slightly lower fuel economy. Overall, E15 fuel is a safe and cost-effective option for most drivers of 2001 and newer model vehicles.

E15 fuel is not suitable for motorcycles or other small engines
E15 fuel, also known as unleaded 88 octane gas, contains 15% ethanol and 85% gasoline. It has been certified for use in any gasoline-powered car with a U.S.-certified emissions system from 2001 or newer, including flexible-fuel vehicles. The Environmental Protection Agency (EPA) and Department of Energy have tested and approved its use in newer models, but not older ones due to variability and age. E15 fuel offers cost savings compared to E10 and non-ethanol fuel, and it burns cleaner, reducing carbon emissions and displacing toxic fuel additives.
However, E15 fuel is not suitable for motorcycles or other small engines. The American Motorcyclist Association (AMA) has expressed concerns about the risks of E15 fuel for motorcycle riders, all-terrain vehicle (ATV) owners, and boat owners. Using E15 in these vehicles can void warranties. The primary issue is that motorcycles and ATVs are not approved by the U.S. for E15 fuel, and using it could damage their engines and fuel systems. Additionally, the AMA worries that the increased availability of E15 fuel could reduce the supply of E0 fuel (gasoline containing zero ethanol), which is preferred by many motorcyclists and required for older machines.
The EPA has misfuelling mitigation regulations in place to ensure that E15 is only used in vehicles that can accept this fuel. These regulations were finalized in 2011 and have not undergone any significant changes affecting motorcyclists or motorcycles. It is important to note that motorcycles and other small engines require E10 fuel or lower, which contains a maximum of 10% ethanol. Dispensing E10 in volumes less than 4 gallons from a dedicated pump is not a violation of EPA requirements, ensuring that motorcyclists can access the appropriate fuel for their vehicles.
When considering the use of E15 fuel, it is crucial to refer to the vehicle's owner's manual to determine the recommended fuel type. For older cars from 2001 or earlier, the recommendation is typically no more than 10% ethanol. While a single tank of E15 may not cause immediate damage, prolonged use can negatively affect the vehicle's performance over time. Therefore, it is essential to follow the manufacturer's guidelines and use the specified fuel type to maintain the optimal condition of motorcycles, small engines, and other incompatible vehicles.
