264 TECHNICAL SPECIFICATIONS
While operating on gasoline with an octane number of 87, hearing a light knocking sound from the engine is not a cause for concern. However, if the engine is heard making a heavy knocking sound, see your dealer immediately. Use of gasoline with an octane number lower than 87 can cause engine failure and may void or not be covered by the New Vehicle Limited Warranty. as hard starting, stalling, and hesitations. If you experience these symptoms, try another brand of gasoline before considering service for the vehicle. Reformulated Gasoline Many areas of the country require the use of cleaner burning gasoline referred to as “Refor- mulated Gasoline”. Reformulated gasoline contains oxygenates and are specifically blended to reduce vehicle emissions and improve air quality. mended. Properly blended reformulated gaso- line will provide improved performance and durability of engine and fuel system components. Materials Added To Fuel Besides using unleaded gasoline with the proper octane rating, gasolines that contain detergents, corrosion and stability additives are recommended. Using gasolines that have these additives will help improve fuel economy, reduce emissions, and maintain vehicle performance. Designated TOP TIER Detergent Gaso- line contains a higher level of deter- gents to further aide in minimizing engine and fuel system deposits. When available, the usage of TOP TIER Deter- gent Gasoline is recommended. Visit for a list of TOP TIER Deter- gent Gasoline Retailers. agents should be avoided. Many of these mate- rials intended for gum and varnish removal may contain active solvents or similar ingredients. These can harm fuel system gasket and diaphragm materials. Gasoline/Oxygenate Blends Some fuel suppliers blend unleaded gasoline with oxygenates such as ethanol. Problems that result from using gasoline containing more than 15% ethanol (E-15) or gasoline containing methanol are not the responsibility of the manufacturer and may void or not be covered under New Vehicle Limited Warranty. CAUTION! DO NOT use E-85, gasoline containing methanol, or gasoline containing more than 15% ethanol (E-15). Use of these blends may result in starting and driveability problems, damage critical fuel system components, cause emissions to exceed the applicable standard, and/or cause the Malfunction Indicator Light to illuminate. Please observe pump labels as they should clearly communicate if a fuel contains greater than 15% ethanol (E-15). |
