■Gasoline quality
In very few cases, driveability prob-
lems 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 Toyota dealer.
■Recommendation of the use of
gasoline containing detergent
additives
●Toyota 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. con-
tains minimum detergent additives
to clean and/or keep clean intake
systems, per EPA’s lowest addi-
tives concentration program.
●Toyota strongly recommends the
use of Top Tier Detergent Gaso-
line. For more information on Top
Tier Detergent Gas
oline and a list
of marketers, pleas e go to the offi-
cial website 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 avail-
able in some cities. These fuels are
typically acceptable for use, provid-
ing they meet other fuel require-
ments.
Toyota 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 gas-
oline that could contain more than
15% ethanol, including from any
pump labeled E30 (30% ethanol
[ ]), E50 (50% ethanol [ ]), E85
(85% ethanol [ ]) (which are only
some examples of f uel containing
more than 15% ethanol).
Fuel infor mation
You must only use unleaded
gasoline.
The engine is designed to
operate at maximum perfor-
mance using unleaded gas-
oline with an octane rating
of 93 (98 RON) or higher. If
an octane rating of 93 (98
RON) fuel is not readily
available in your area,
unleaded gasoline with an
octane rating of 91 (95 RON)
may be used with no detri-
ment to engine durability or
driveability. However, you
may notice a slight
decrease in maximum
engine performance and
you may hear some knock-
ing (pinging) of an engine
while using an octane rating
of 91 (95 RON) fuel.
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..
