8-1. Specifications

Fuel information

You must only use unleaded gasoline.
Select octane rating 87 (Research Octane
Number 91) or higher. Use of unleaded
gasoline with an octane rating lower than
87 may result in engine knocking.
Persistent knocking can lead to engine
damage.
At minimum, the gasoline you use should
meet the specifications of ASTM D4814 in
the U.S.A.
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 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. contains
minimum detergent additives to clean
and/or keep clean intake systems, per
EPA's lowest additives concentration
program.
• Toyota strongly recommends the use of
Top Tier Detergent Gasoline. For more
information on Top Tier Detergent
Gasoline and a list of marketers, please
go to the official 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 available in
some cities. These fuels are typically
acceptable for use, providing they meet
other fuel requirements.
394
Toyota recommends these fuels, since the
formulations allow for reduced vehicle
emissions.
Use of ethanol blended gasoline in a
gasoline engine
• Use only gasoline containing up to 15%
ethanol.
DO NOT use any flex-fuel or gasoline
that could contain more than 15%
ethanol, including from any pump
labeled E30 (30% ethanol [
(50% ethanol [ B ]), E85 (85% ethanol
[ ]) (which are only some examples of
C
fuel containing more than 15%
ethanol).
• If you use gasohol in your vehicle, be
sure that it has an octane rating no
lower than 87.
• Toyota does not recommend the use of
gasoline containing methanol.
Non-recommendation of the use of
gasoline containing MMT
Some gasoline contains an octane
enhancing additive called MMT
(Methylcyclopentadienyl Manganese
Tricarbonyl).
Toyota 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 Toyota dealer for
service.
