Additives
To 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, nothing should have to be added to the fuel.However, some gasolines contain only the minimumamount of additive required to meet U.S. EnvironmentalProtection Agency regulations. To help keep fuelinjectors and intake valves clean, or if the vehicleexperiences problems due to dirty injectors or valves,look for gasoline that is advertised as TOP TIERDetergent Gasoline.
For customers who do not use TOP TIER DetergentGasoline regularly, one bottle of GM Fuel SystemTreatment PLUS, added to the fuel tank at every engineoil change, can help clean deposits from fuel injectorsand intake valves. GM Fuel System Treatment PLUS isthe only gasoline additive recommended by GeneralMotors.
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 availablein your area. We recommend that you use thesegasolines, if they comply with the specifications
described earlier. However, E85 (85% ethanol) andother fuels containing more than 10% ethanol mustnot be used in vehicles that were not designed forthose fuels.
Notice:This vehicle was not designed for fuel thatcontains methanol. Do not use fuel containingmethanol. It can corrode metal parts in the fuelsystem and also damage plastic and rubber parts.That damage would not be covered under thevehicle warranty.
Some gasolines that are not reformulated for lowemissions can contain an octane-enhancing additivecalled methylcyclopentadienyl manganese tricarbonyl(MMT); ask the attendant where you buy gasolinewhether the fuel contains MMT. We recommend againstthe use of such gasolines. Fuels containing MMT canreduce the life of spark plugs and the performance ofthe emission control system could be affected. Themalfunction indicator lamp might turn on. If this occurs,return to your dealer/retailer for service.
Fuel E85 (85% Ethanol)
This vehicle can use either unleaded gasoline or85% ethanol fuel (E85). We encourage the use ofE85 in vehicles that are designed to use it. The ethanolin E85 is a“renewable”fuel, meaning it is made fromrenewable sources such as corn and other crops.
