In most cases, nothingshould have to be added to the fuel.However, some gasolines containonly the minimum amount ofadditive required to meet U.S.Environmental Protection Agencyregulations. To help keep fuelinjectors and intake valves cleanand avoid problems due to dirtyinjectors or valves, look for gasolinethat is advertised as TOP TIERDetergent Gasoline. Look for theTOP TIER label on the fuel pump toensure gasoline meets enhanceddetergency standards developed bythe auto companies. A list ofmarketers providing TOP TIERDetergent Gasoline can be found atwww.toptiergas.com.For customers who do not use TOPTIER Detergent Gasoline regularly,one bottle of GM Fuel SystemTreatment PLUS, added to the fueltank at every engine oil change, canhelp clean deposits from fuelinjectors and intake valves. GM FuelSystem Treatment PLUS is the onlygasoline additive recommended byGeneral Motors. It is available atyour dealer.Gasolines containing oxygenates,such as ethers and ethanol, andreformulated gasolines might beavailable in your area. Werecommend that you use thesegasolines, if they comply with thespecifications described earlier.However, E85 (85% ethanol) andother fuels containing more than15% ethanol must not be used invehicles that were not designed forthose fuels.Notice: This vehicle was notdesigned for fuel that containsmethanol. Do not use fuelcontaining methanol. It cancorrode metal parts in the fuelsystem and also damage plasticand rubber parts. That damagewould not be covered under thevehicle warranty.Some gasolines that arenot reformulated for lowemissions can contain anoctane-enhancing additive calledmethylcyclopentadienyl manganesetricarbonyl (MMT); ask the attendantwhere you buy gasoline whether thefuel contains MMT. We recommendagainst the use of such gasolines.Fuels containing MMT can reducespark plug life and affect emissioncontrol system performance. Themalfunction indicator lamp mightturn on.
