Ethanol-Free Reformulated Gasoline
Product Offering
Ethanol-Free Gasoline for Specialty Engines & Premium Performance
When it comes to protecting and powering specialty engines, additives can only go so far. Sprague delivers performance right at the pump — no extra treatments, no compensating for ethanol-related issues.
Formulated with isobutanol instead of ethanol, Sprague’s 93-octane ethanol-free oxygenated and reformulated gasoline (RFG) delivers more energy per gallon than E10 blends, resists moisture, and prevents damaging phase separation. It’s built for engines that demand the best, from high-performance boats and race cars to classic vehicles and essential work equipment.
From the Dock: A Customer’s Perspective
Sprague partnered with East Moriches Boat and Motor to bring the first 93-octane RFG to the Northeast.
About the partnership, East Moriches Marina owner Conrad Kreuter said, "Our customers have been asking for this, and we're excited to provide them with high-quality fuel that will help protect their boats for years to come.”
Only the Best Fuel for Your Engine
Ethanol-blended fuels can attract moisture, leading to phase separation, corrosion, and degraded performance, especially in vented fuel systems. Ethanol-free gasoline eliminates these risks and gives you:
More reliable starts and consistent
engine performance
Longer equipment life by protecting
hoses, gaskets, and tanks
Better fuel stability for
seasonal or infrequent use
Who benefits most from ethanol-free gasoline?
- Boaters and marinas
- Race cars and motorsport teams
- Classic and collector vehicle owners
- Landscapers and grounds crews
- Small engine users (generators, chainsaws, snowmobiles, etc.)
Use A Cleaner Option
In many metropolitan areas with higher levels of air pollution, the EPA requires RFGs to help reduce smog-forming emissions and toxic air pollutants. Many ethanol-free fuels available today are simply “pure gas” without added oxygenates and are not compliant with EPA’s RFG standards—meaning they cannot be legally sold in certain markets.
Sprague’s ethanol-free RFG uses isobutanol as its oxygenate, meeting RFG requirements in markets like New York, New Jersey, and Connecticut while providing:
- Cleaner-burning performance that supports improved air quality
- Lower evaporative emissions and reduced greenhouse gas output compared to non-reformulated fuels
- Strong performance per gallon with compatibility for a wide range of specialty engines
