Gasoline For proper operation of your car's emission controls, your engine is designed to use unleaded fuel only. CAUTION: Using leaded or even low-lead gasoline could damage some of your emission controls, and also void their coverage under the emission controls warranty. Use gasoline from pumps labeled unleaded, with a pump octane number of 86 or higher. Use of a lower octane gasoline can cause persistent, heavy "spark knock" (a metallic rapping noise), which can lead to engine damage if severe. CAUTION: If you notice steady spark knock while holding a steady speed on a level road, try changing brands of gasoline. If the spark knock persists, consult your Honda dealer. Failure to do so is considered misuse, and misuse is not covered under the New Car Warranty. Occasionally you may notice light spark knock while accelerating or driving up hills. This is no cause for concern, it simply means your engine is running at its most economical. Oxygenated Fuels Some conventional gasolines are being blended with alcohol or an ether compound to increase the gasoline's octane. These gasolines are collectively referred to as oxygenated fuels. Some areas of the United States and Canada use oxygenated fuels to help meet clean air standards. If you use an oxygenated fuel, be sure it meets the minimum octane rating requirement as recommended. ETHANOL (ethyl or grain alcohol) - Gasoline containing more than 10% ethanol by volume may cause starting and/or performance problems. Gasoline containing ethanol may be marketed under the name "Gasohol." METHANOL (methyl or wood alcohol) - Gasoline containing methanol must contain cosolvents and corrosion inhibitors to protect the fuel system. Gasoline containing more than 5% methanol by volume may cause starting and/or performance problems and may damage metal, rubber and plastic parts of your fuel system. MTBE (Methyl Tertiary Butyl Ether) - You may use gasoline containing up to 15% MTBE by volume.
