Fuel Requirements:

Each map lists the minimum required octane. A higher octane fuel can be used safely on a map designed for lower octane. DO NOT use maps designed for higher octane with lower octane fuels. Top Tier gasoline should be used where available.

• Maps designated with "91 OCT or 95 RON " are for use with 91 and 92 octane/95 RON fuel or better.

• Maps designated with "93 OCT or 98 RON" are for use with 93 octane/98 RON fuel or better.

  • 94 octane with 0% Ethanol should run the ACN91 Map.
