Octane rating Octane rating indicates a gasoline's ability to resist engine-damaging “knock” caused by pre-ignition. Using the correct grade of gasoline is very important to help prevent engine damage and loss of engine performance. The recommended gasoline octane rating for your engine is listed on a label inside of the fuel filler flap. This rating may be specified according to AKI (CLC) or RON (ROZ) standards. If unleaded Premium grade gasoline is specified for your vehicle, then Volkswagen recommends using TOP TIER Detergent Gasoline with a minimum octane rating of 91 AKI (95 RON). For more infor- mation on TOP TIER Detergent Gasoline, please go to the official Web site, http://www.toptiergas.com. The gasoline grades most commonly sold in the United States and Canada have the following octane ratings, which can usually be found on the filler pump: x Premium grade: 91 to 96 AKI x Regular grade: 87 to 90 AKI Unleaded gasoline Unleaded gasoline is available throughout the USA and Canada. Volkswagen recommends that you do not take your vehicle to places where unleaded gasoline may not be available. Gasoline containing alcohol or MTBE You may use unleaded gasoline blended with alcohol or MTBE (methyl tertiary butyl ether), commonly referred to as oxygenated fuels, if the blended mixture meets the following criteria: Blends of gasoline and methanol (wood alcohol or methyl alcohol): x Anti-Knock Index (AKI) must be 87 or higher. x Blend must contain no more than 3% methanol. x Blend must contain more than 2% co-solvents.
