*: The engine oil capacity is a reference quantity to be used when changing
the engine oil. Warm up and turn off the engine, wait more than 5 minutes,
and check the oil level on the dipstick.

Engine oil selection
“Toyota Genuine Motor Oil” is us ed in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to sat -
isfy the following grade and viscosity.
Oil grade: ILSAC GF-5 multigrade engine oil
Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice
for good fuel economy and
good starting in cold weather.
If SAE 0W-20 is not available,
SAE 5W-20 oil may be used.
However, it must be replaced
with SAE 0W-20 at the next oil
change.

5428-1. Specifications
Oil viscosity (0W-20 is explained here as an example):• The 0W in 0W-20 indicates the characteristic of the oil which allows cold
startability. Oils with a lower value before the W allow for ea sier starting
of the engine in cold weather.
• The 20 in 0W-20 indicates the viscosity characteristic of the oil when the
oil is at high temperature. An oil with a higher viscosity (one with a
higher value) may be better suited if the vehicle is operated a t high
speeds, or under extreme load conditions.
How to read oil container label:
The International Lubricant
Specification Advisory Commit-
tee (ILSAC) Certification Mark
is added to some oil containers
to help you select the oil you
should use.

Fuel information
■Gasoline quality
In very few cases, driveability problems may be caused by the b rand of gaso-
line you are using. If driveability problems persist, try changing the brand of
gasoline. If this does not correct the problem, consult your To yota dealer.
■ Recommendation of the use of gaso line containing detergent additives
● Toyota recommends the use of gasoline that contains detergent a dditives to
avoid build-up of engine deposits.
● All gasoline sold in the U.S.A. contains minimum detergent addi tives to
clean and/or keep clean intake systems, per EPA’s lowest additi ves concen-
tration program.
● Toyota strongly recommends the use of Top Tier Detergent Gasoli ne. For
more information on Top Tier Detergent Gasoline and a list of m arketers,
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 fue ls are typically
acceptable for use, providing they meet other fuel requirements .
Toyota recommends these fuels, since the formulations allow for reduced
vehicle emissions.
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.

5508-1. Specifications
■Non-recommendation of the use of blended gasoline
●If you use gasohol in your vehicle, be sure that it has an octa ne rating no
lower than 87.
● Toyota does not recommend the use of gasoline containing methan ol.
■ Non-recommendation of the use of gasoline containing MMT
Some gasoline contains an octane enhancing additive called MMT (Methylcy-
clopentadienyl 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 adv ersely
affected.
The malfunction indicator lamp on the instrument cluster may come on. If this
happens, contact your Toyota dealer for service.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time whi le accelerat-
ing or driving uphill. This is normal and there is no need for concern.
●
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, E50, E85 (which are only some
examples of fuel containing more than
15% ethanol).
DO NOT use gasoline contain-
ing more than 15% ethanol.
(30% ethanol)
(50% ethanol)
(85% ethanol)
