Gasolines Containing Mtbe; Gasolines Containing Mmt; Gasolines Containing Alcohol; Fuel Tank Capacity - Lexus GS300 1998 Owner's Manual

ENGINE
Improved gasolines
The American Automobile Manufacturers Association
(AAMA) has developed a specification of improved
gasolines. The AAMA specification offers optimal fuel
information for better vehicle performance and better
protection of your engine.
Lexus recommends the use of gasolines that meet the AAMA
specification, if available, for improved drivability and
emission control system.

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 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
368
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.
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.
