Ethanol is a renewable, oxygenated fuel known for increasing knock resistance and promoting cooler combustion temperatures. These properties allow tuners to push more timing, boost, and compression safely, making ethanol blends a top choice for performance enthusiasts looking to extract every bit of horsepower from their builds.
Ethanol not only improves performance but also supports cleaner combustion, especially when the fuel is consistent and properly matched to the engine’s setup.
Pump E30 can be inconsistent in both ethanol content and quality. E30-R is a purpose-blended ethanol fuel that delivers predictable performance, making it ideal for tuners who rely on precise fueling. Whether you’re running a flex-fuel build or a weekend track car, E30-R offers the reliability pump gas cannot.
Pump E85 often varies by season and geography. E85-R provides consistent, high ethanol content, allowing for more aggressive ignition timing, higher boost pressure, and cooler intake temps. It’s a trusted option for high-output turbocharged, supercharged, or naturally aspirated engines built for serious performance.
For the highest ethanol content available, E98 offers nearly pure ethanol designed for drag, circuit, and other extreme racing applications. It requires compatible fuel systems and tuning to match, but delivers maximum cooling and detonation resistance under high stress.
Green E15 is a lower ethanol, renewable blend suitable for modern vehicles approved for E15 use. It adds oxygen for more complete combustion while supporting environmental performance standards.
