Recommended viscosity: SAE 0W-20
SAE 0W-20 is the best choice for
good fuel economy and good start-
ing 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.

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 easier 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 at high speeds, or
under extreme load conditions.

How to read oil container label:
The International Lubricant Specifi-
cation Advisory Committee
(ILSAC) Certification Mark is added
to some oil containers to help you
select the oil you should use.

Engine oil selection

“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-5 multigrade engine oil
Recommended viscosity: SAE 5W-30
SAE 5W-30 is the best choice for
good fuel economy and good start-
ing in cold weather.
If SAE 5W-30 is not available, SAE
10W-30 oil may be used. However,
it should be replaced with SAE 5W-
30 at the next oil change.

Oil viscosity (5W-30 is explained here as an example):

• The 5W in 5W-30 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 30 in 5W-30 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.

Fuel 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 informa-

tion on Top Tier Detergent Gasoline and a list of marketers, please go to the official

website www.toptiergas.com.

You must only use unleaded gasoline.
Select premium unleaded gasoline with an octane rating of 91 (Research
Octane Number 96) or higher required for optimum engine performance
and fuel economy.
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..

530

8-1. Specifications

■

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, pro-

viding they meet other fuel requirements.
Lexus recommends these fuels, since the formulations allow for reduced vehicle emis-

sions.

■

Non-recommendation of the use of blended gasoline

●

If you use gasohol in your vehicle, be sure that it has an octane rating no lower than 91.

●

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 driv-

ing uphill. This is normal and there is no need for concern.

●

Use only gasoline containing up to 15% etha-

nol.

DO NOT use any flex-fuel or gasoline that

could contain more than 15% ethanol, includ-

ing from any pump labeled E30, E50, E85

(which are only some examples of fuel con-

taining more than 15% ethanol).

DO NOT use gasoline con-
taining more than 15% ethanol.

(30% ethanol)

(50% ethanol)

(85% ethanol)

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 may cause persistent heavy knocking.

At worst, this may lead to engine damage and will void the vehicle warranty.

■

Fuel-related poor driveability

If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is encoun-

tered 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.
