"Toyota Genuine Motor Oil" is used in your Lexus vehicle. Use Lexus approved
"Toyota Genuine Motor Oil" or equivalent to satisfy the following grade and
viscosity.

Oil grade: ILSAC GF-6B multigrade engine oil
Recommended viscosity: SAE 0W-16

Outside temperature

SAE 0W-16 is the best choise for good fuel economy and good starting in cold
wheather. If SAE 0W-16 is not available, SAE 0W-20 oil may be used. However, it
must be replaced with SAE 0W-16 at the next oil change.

■

How to read oil container label

API registered mark is added to some oil con-
tainers to help you select the oil you should use.
Oil viscosity (0W-16 is explained here as an ex-
ample):

●

The 0W in 0W-16 indicates the characteristic of the oil which allows cold
startability.
Oils with a lower value before the W allow for easier starting of the engine in
cold weather.

●

The 16 in 0W-16 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 at high speeds, or under extreme load conditions.

Cooling system

*1 :

The engine oil capacity is a reference quantity to be used when changing the engine

oil. Warm up the engine and turn off the hybrid system, wait more than 5 minutes, and

check the oil level on the dipstick.

Fuel information

You must only use unleaded gasoline in your vehicle.
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.
Use of octane rating 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.

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

10-1. Specifications

748

■

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% ethanol, 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 87.

●

Lexus 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 (Methylcyclopenta-
dienyl Manganese Tricarbonyl).
Lexus 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 Lexus dealer for service.

■

If your engine knocks

●

Consult your Lexus dealer.

●

You may occasionally notice light knocking for a short time while accelerating or
driving uphill. This is normal and there is no need for concern.

NOTICE

■

Notice on fuel quality

●

Do not use improper fuels. If improper fuels are used, the engine will be damaged.

●

Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle's three-way catalytic converters
causing the emission control system to malfunction.

●

Do not use gasohol other than the type previously stated.
Other gasohol may cause fuel system damage or vehicle performance problems.

●

Using unleaded gasoline with an octane number or rating lower than the level previ-
ously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.

■

Fuel-related poor driveability

If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encountered
after using a different type of fuel, discontinue the use of that type of fuel.

When refueling with gasohol

Take care not to spill gasohol. It can damage your vehicle's paint.

Tire ply composition and materials

Plies are layers of rubber-coated parallel cords. Cords are the strands which form the
plies in a tire.

Radial tires or bias-ply tires

A radial tire has [RADIAL] on the sidewall. A tire not marked [RADIAL] is a bias-ply
tire.

TUBELESS or TUBE TYPE

A tubeless tire does not have a tube and air is directly put into the tire. A tube type tire
has a tube inside the tire and the tube maintains the air pressure.

Load limit at maximum cold tire inflation pressure

Maximum cold tire inflation pressure

This means the pressure to which a tire may be inflated.
