Features and Benefits

Performs well in virtually all gasoline enginesBlends of 10% ethanol (E10) can be used in virtually any engine on or off the road today. In fact, more than 98% of all U.S. gasoline contains up to 10% ethanol. A 15% blend (E15) can be safely used in any vehicle made in model year 2001 or later. 1
Reduced tailpipe emissionsEthanol blends reduce total toxic tailpipe emissions, which include greenhouse gasses, by up to 50% compared to 100% gasoline.2
Good for farmers and the economyAccording to studies, in 2017 the U.S. ethanol industry helped support nearly 36,000 jobs, contributed more than $45 billion to the Gross Domestic Product and generated $10 billion in tax revenue at all levels.3
Non-toxic octane boosterPure ethanol (E100) is often used as an organic additive in conventional gasoline to raise octane ratings for optimum engine performance. Using a fuel with an octane rating that matches the engine specification ensures maximum combustion and, therefore, power efficiency.
