FUEL RECOMMENDATION (except Supercharger) Your vehicle is designed to operate on unleaded gasoline with an octane rating of at least 87 AKI (Anti-Knock Index) (Research octane number 91). (Supercharger) Unleaded premium gasoline with an octane rating of at least 91 AKI (Anti-Knock Index) number (Research octane number 96). If unleaded premium gasoline is not available, unleaded regular gasoline with an octane rating of at least 87 AKI (Research octane number 91) can be used, but only under the following precautions: ● Have the fuel tank filled only partially with unleaded regular gasoline, and fill up with unleaded premium as soon as possible. ● Avoid full throttle driving and abrupt acceleration. CAUTION ● Using a fuel other than that specified could adversely affect the emission control system, and may also affect the warranty coverage. ● Under no circumstances should a leaded gasoline be used, since this will damage the three-way catalyst. If you use oxygenate-blend gasoline, please take the following precautions as the usage of such fuels may cause vehicle performance problems and/or fuel system damage. ● The fuel should be unleaded and have an octane rating no lower than that recommended for unleaded gasoline. ● If an oxygenate-blend, excepting a methanol blend, is used, it should contain no more than 10% oxygenate. (MTBE may, however, be added up to 15%.) ● If a methanol blend is used, it should contain no more than 5% methanol (methyl alcohol, wood alcohol). It should also contain a suitable amount of appropriate cosolvents and corrosion inhibitors. If not properly formulated with appropriate cosolvents and corrosion inhibitors, such methanol blends may cause fuel system damage and/or vehicle performance problems. At this time, sufficient data is not available to ensure that all methanol blends are suitable for use in NISSAN vehicles. Reformulated Gasoline Some fuel suppliers are now producing reformulated gasolines. These gasolines are specially designed to reduce vehicle emissions. NISSAN supports efforts towards cleaner air and suggests that you use reformulated gasoline when available. Gasoline containing oxygenates Some fuel suppliers sell gasoline containing oxygenates such as ethanol, MTBE and methanol with or without advertising their presence. Nissan does not recommend the use of fuels of which the oxygenate content and the fuel compatibility for your NISSAN cannot be readily determined. If in doubt, ask your service station manager. 10-4 Technical and consumer information
