jGENERAL INFORMATION 49 NOTICE Engine "knocking" or "pinging" can lead to severe engine damage. If engine "knocking" or "pinging" occurs, use a different brand of gasoline of a higher octane rating. Gasoline quality is important. Fuels of low quality or not meeting standard industry specifications may result in unsatisfactory performance. Operating problems that result from the use of poor quality or nonrecommended fuel may not be covered under your warranty. Fuels Containing Oxygenates Gasoline frequently contains oxygenates (alcohols and ethers) especially in areas of the U.S. and Canada which are required to sell such reformulated fuels as part of a strategy to reduce exhaust emissions. The types and volume of fuel oxygenates approved for use in unleaded gasoline by the U.S. Environmental Protection Agency include a broad range of alcohols and ethers, but only two components have seen any significant level of commercial use. Gasoline/Alcohol Blends - Gasoline containing up to 10% ethanol (alcohol produced from agricultural products such as corn), also known as "gasohol" is approved for use. NOTICE Using blends of unleaded gasoline and methanol (wood alcohol) can damage the fuel system and result in poor engine performance. Avoid using methanol whenever possible, and never use "gasohol" containing more than 5% methanol. Gasoline/Ether Blends - The most common ether is methyl tertiary butyl ether (MTBE). You may use gasoline containing up to 15% MTBE. j ○Other oxygenates approved for use in unleaded gasoline include TAME (up to 16.7%) and ETBE (up to 17.2%). Fuel containing these oxygenates can also be used in your Kawasaki. NOTE
