Cleaner Burning Gasoline; Oxygenates In Gasoline; Sulfur In Gasoline; Gasoline Containing Mmt - Lexus RX300 2001 Owner's Manual

Cleaner burning gasoline

Cleaner burning gasoline, including reformulated
gasoline that contains oxygenates such as ethanol or
MTBE is available in many areas.
Lexus recommends the use of cleaner burning gasoline and
appropriately blended reformulated gasoline. These types of
gasoline provide excellent vehicle performance, reduce
vehicle emissions, and improve air quality.

Oxygenates in gasoline

Lexus allows the use of oxygenate blended gasoline
where the oxygenate content is up to 10% ethanol or 15%
MTBE. If you use gasohol in your Lexus, be sure that it has
an octane rating no lower than 87.
Lexus does not recommend the use of gasoline containing
methanol.

Sulfur in gasoline

If your vehicle is certified to California Emission
Regulation, the vehicle is designed to operate on
California cleaner burning gasoline (CBG) that contains
lower sulfur. If you cannot use California CBG, your
emission control system may suffer damage and turn on
the Malfunction Indicator Lamp.
If the malfunction is caused by the type of fuel used, repairs
may not be covered by your warranty.

Gasoline containing MMT

Some gasoline contain an octane enhancing additive
called MMT (Methylcyclopentadienyl Manganese
Tricarbonyl).
Lexus does not recommend the use of gasoline that contains
MMT. If fuel containing MMT is 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.
Gasoline quality
In a very few cases, you may experience driveability problems
caused by the particular gasoline that you are using. If you
continue to have unacceptable driveability, try changing
gasoline brands. If this does not rectify your problem, then
consult your Lexus dealer.
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.
