■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following situations,
oil consumption may increase, and engine oil may need to be refilled in between oil
maintenance intervals.
●When the engine is new, for example directly after purchasing the vehicle or after
replacing the engine
●If low quality oil or oil of an inappropriate viscosity is used
●When driving at high engine speeds or with a heavy load, when towing, or when driving
while accelerating or decelerating frequently
●When leaving the engine idling for a long time, or when driving frequently through
heavy traffic
■After changing the engine oil (GS350/GS200t)
The engine oil maintenance data should be reset. Perform the following procedures:
Press or of the meter control switch and select .
Press or of the meter control switch and select “Vehicle Settings”. Then press .
Press or of the meter control switch and select “Oil Maintenance”. Then press
.
Select the “Yes” and press .
A message is displayed on the multi-informa-
tion display.

Recommended viscosity (SAE):
SAE 0W-20 is filled into your Lexus
vehicle at manufacturing, and the
best choice for good fuel economy
and good starting in cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used. How-
ever, it should be replaced with SAE
0W-20 at the next oil change.
If you use SAE 10W-30 or a higher
viscosity engine oil in extremely low
temperatures, the engine may
become difficult to start, so SAE
0W-20 or 5W-30 engine oil is rec-
ommended.

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 viscosit y 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 labels:
Either or both API registered marks are added to some oil containers to help
you select the oil you should use.
API Service Symbol
Top portion: “API SERVICE SN”
means the oil quality designation by
American Petroleum Institute (API).
Center portion: “SAE 0W-20”
means the SAE viscosity grade.
Lower portion: “Resource-Conserv-
ing” means that the oil has fuel-saving
and environmental protection capa-
bilities.

tion Mark is displayed on the front of the container.

■Engine oil selection
“Toyota Genuine Motor Oil SAE 0W-20 for Downsized Turbo Gasoline
Engines” is used in your Lexus vehicle. Use Lexus approved “Toyota Genuine
Motor Oil SAE 0W-20 for Downsized Turbo Gasoline Engines” or equiva-
lent to satisfy the following grade and viscosity.
Oil grade:
“Toyota Genuine Motor Oil SAE 0W-20 for Downsized Turbo Gasoline
Engines” or API grade SL “Energy-Co nserving”, SM “Energy-Conserving” or
SN “Resource-Conserving”; or ILSAC multigrade engine oil
Viscosity grade:
SAE 0W-20 and 5W-30
Recommended viscosity (SAE):
“Toyota Genuine Motor Oil SAE
0W-20 for Downsized Turbo Gaso-
line Engines” is filled into your Lexus
vehicle at manufacturing, and SAE
0W-20 is the best choice for good

cold weather.
If SAE 0W-20 oil is not available,
SAE 5W-30 oil may be used. How-
ever, it should be replaced with SAE
0W-20 at the next oil change.

■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus recom-
mends the use of approved “Toyota Ge nuine Motor Oil”. Another motor oil of
matching quality can also be used.
Oil grade:
5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving” or SN
“Resource-Conserving”; or ILSAC multigrade engine oil
15W-40:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
SAE 5W-30 is filled into your Lexus
vehicle at manufacturing, and the
best choice for good fuel economy
and good starting in cold weather.
If you use SAE 10W-30 or a higher
viscosity engine oil in extremely low
temperatures, the engine may
become difficult to start, so SAE
5W-30 engine oil is recommended.
