Important fuel quality information


Only use fuel equal to or higher than specified. Never use a lower octane fuel. Always follow our fuel guide, especially with race fuel and Ethanol, where available. Dynos are for reference only. Results will vary. Contributing factors include the vehicle condition, vehicle setup, dyno type, dyno setup, environmental factors, fuel quality, and more. When describing fuels, the North American Region (NAR) uses the Anti-Knock Index (AKI), (RON+MON)/2, or (R+M)/2. The Rest of the World (ROW) uses RON. RON is Research Octane Number and MON is Motor Octane Number. Please Note: Each vehicle's year, make, and model may have multiple factory engine or transmission controller software part numbers, known as box codes, each with unique revisions. Manufacturers periodically release software updates that alter this information, which can only be determined by scanning the controller and is not publicly provided. Due to the variety of codes, some stages, octane levels, features, or options may not be available for specific codes. Therefore, our website provides a general guide based on general info such as Year, Make, and Model. Our system allows you to request unavailable software, and we offer a 30-day money-back guarantee if you're not satisfied.
