Recommended to use premium unleaded gasoline with octane rating of 91 (Re-
search OctaneNumber of 96) or higher for optimum engine performance. You
may use unleaded gasoline with octane rating as low as 87 (Research Octane
Number of 91). In this case, engine performance may be decreased.

in the U.S.A.
INFORMATION
■
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 additives concentration program.
●
Lexus strongly recommends the use of Top Tier Detergent Gasoline. For more infor-
mation on Top Tier Detergent Gasoline and a list of marketers, please go to the official

■
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 requirements.
Lexus recommends these fuels, since the formulations allow for reduced vehicle emis-
sions.
