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-
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 ra ting is less than 
91, damage to the engine may 
occur and may void the vehicle war-
ranty.
At minimum, the gasoline you use 
should meet the specifications of 
ASTM D4814 in the U.S.A..
