Gasoline SpecificationsAt a minimum, gasoline should meet ASTMspecification D 4814 in the United States orCAN/CGSB-3.5 or 3.511 in Canada. Some gasolinescontain an octane-enhancing additive calledmethylcyclopentadienyl manganese tricarbonyl (MMT).We recommend against the use of gasolinescontaining MMT. See Additives on page 5-6 foradditional information.California FuelIf your vehicle is certified to meet California EmissionsStandards, it is designed to operate on fuels thatmeet California specifications. See the underhoodemission control label. If this fuel is not availablein states adopting California emissions standards, yourvehicle will operate satisfactorily on fuels meetingfederal specifications, but emission control systemperformance might be affected. The malfunctionindicator lamp could turn on and your vehicle might faila smog-check test. See Malfunction Indicator Lampon page 3-63. If this occurs, return to your authorizeddealer/retailer for diagnosis. If it is determined thatthe condition is caused by the type of fuel used,repairs might not be covered by your warranty.AdditivesTo provide cleaner air, all gasolines in the United Statesare now required to contain additives that help preventengine and fuel system deposits from forming, allowingthe emission control system to work properly. In mostcases, you should not have to add anything to the fuel.However, some gasolines contain only the minimumamount of additive required to meet U.S. EnvironmentalProtection Agency regulations. To help keep fuel injectorsand intake valves clean, or if your vehicle experiencesproblems due to dirty injectors or valves, look for gasolinethat is advertised as TOP TIER Detergent Gasoline.Also, your dealer/retailer has additives that will helpcorrect and prevent most deposit-related problems.Gasolines containing oxygenates, such as ethers andethanol, and reformulated gasolines might be available inyour area. We recommend that you use these gasolines,if they comply with the specifications described earlier.However, E85 (85% ethanol) and other fuels containingmore than 10% ethanol must not be used in vehicles thatwere not designed for those fuels.5-6
