4558-1. Specifications
LS500_OM_(U)_1810 8
Vehicle specifications ■
Gasoline quality
In very few cases, driveability problems may
be caused by the brand of gasoline you are
using. If driveability problems persist, try
changing the brand of gasoline. If this does
not correct the problem, consult your Lexus
dealer. ■
Recommendation of the use of gasoline
containing detergent additives●
Lexus recommends the use of gasoline
that contains detergent additives to avoid
the build-up of engine deposits.●
All gasoline sold in the U.S.A. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA’s lowest additive s concentration pro-
gram.
●
Lexus strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent Gaso-
line and a list of marketers, please go to
the official websit e www.toptiergas.com.
■
Recommendation of the use of low
emissions gasoline
Gasolines containing oxygenates such as
ethers and ethanol, as well as reformulated gasolines, are available in some cities.
These fuels are typically acceptable for use,
providing they meet other fuel require-
ments.
Lexus recommends these fuels, since the
formulations allow for reduced vehicle
emissions. ■
Non-recommendation of the use of
blended gasoline ●
Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15% etha-
nol, including from any pump labeled
E30 (30% ethanol [ ]), E50 (50%
ethanol [ ]), E85 (85% ethanol [ ])
(which are only some examples of fuel
containing more than 15% ethanol).
●
If you use gasohol in your vehicle, be sure
that it has an octane rating no lower than
91. ●
Lexus does not recommend the use of
gasoline containing methanol. ■
Non-recommendation of the use of gas-
oline containing MMT
Some gasoline contains an octane enhanc-
ing additive called MMT (Methylcyclopen-
tadienyl Manganese Tricarbonyl).
Lexus does not recommend the use of gas-
oline 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 hap-
pens, contact your Lexus dealer for service.
■
If your engine knocks
●
Consult your Lexus dealer.
●
You may occasionally notice light knock-
ing for a short time wh ile accelerating or Fuel information You must only use unleaded gaso-
line.
Select premium unleaded gasoline
with an octane rating of 91
(Research Octane Number 96) or
higher required for optimum
engine performance and fuel econ-
omy.
If the octane rating is less than 91,
damage to the engine may occur
and may void the vehicle warranty.
At minimum, the gasoline you use
should meet the specifications of
ASTM D4814 in the U.S.A. A
B C

no need for concern.
NOTICE■
Notice on fuel quality●
Do not use improper fuels. If improper
fuels are used, the engine will be dam-
aged.●
Do not use leaded gasoline.
Leaded gasoline can cause damage to
your vehicle’s three-way catalytic con-
verters causing the emission control
system to malfunction.●
Do not use gasohol other than the type
previously stated.
Other gasohol may cause fuel system
damage or vehicle performance prob-
lems.●
Using unleaded gasoline with an
octane number or rating lower than
the level previously stated may cause
persistent he avy knocking.
At worst, this may lead to engine dam-
age and will void the vehicle warranty.■
When refueling with gasohol
Take care not to spill gasohol. It can dam-
age your vehicle’s paint.
■
Fuel-related poor driveability
If poor driveability is encountered after
using a different type of fuel (poor hot
starting, vaporization, engine knocking,
etc.), discontinue the use of that type of
fuel.
