ENGINE Gasolines containing MTBE Gasolines that contain MTBE (Methyl Tertiary-Butyl Ether) are available in the market. If you use a gasoline mixed with MTBE, make certain that it does not contain more than 15% of MTBE. If the use of gasolines containing MTBE causes poor drivability and/or poor fuel economy, you should stop using them. Gasolines containing alcohol Gasohol is a mixture of gasoline and ethanol. If you use gasohol in your Lexus, be sure that it is unleaded, has an octane rating no lower than 87 and does not contain more than 10% ethanol. Lexus does not recommend the use of gasolines containing methanol. If you use gasoline containing methanol, use only gasoline meeting the requirements above and also containing less than 5% methanol with cosolvents and corrosion inhibitors for methanol. Gasolines containing MMT Some gasolines contain an octane-enhancing additive called MMT (methylcyclopentadienyl manganese tricarbonyl). Lexus does not recommend the use of gasolines that contain MMT. If fuels containing MMT are used, your emission control system may be adversely affected. The Malfunction Indicator Lamp on the instrument cluster may come on. If this happens, contact your Lexus dealer for service. NOTICE D Do not use gasohol other than stated above. It will cause fuel system damage or vehicle performance problems. D If drivability problems are encountered (poor hot starting, vaporizing, engine knock, etc.), discontinue its use. D Take care not to spill gasohol during refueling. Gasohol may cause paint damage. Fuel tank capacity 78 L (20.6 gal., 17.2 lmp.gal.)
