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.
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.
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.
