Maintenance and care
GS350_250_OM_OM30E16E_(EE)
Wipe the dipstick and reinsert it fully.
■Adding engine oil
If the oil level is below or near the
low level mark, add engine oil of
the same type as that already in
the engine.
Make sure to check the oil type and prepare the items needed before
adding oil.Remove the oil filler cap by turning it counterclockwise.
Add engine oil slowly, checking the dipstick.
Install the oil filler cap by turning it clockwise.
■Engine oil consumption
A certain amount of engine oil will be consumed while driving. In the following situa-
tions, 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

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.
However, 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, 5W-20 or
5W-30 engine oil is recom-
mended.
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.

“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus rec-
ommends the use of approved “Toyota Genuine 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 and 20W-50:
API grade SL, SM or SN multigrade engine oil
Recommended viscosity (SAE):
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.
Oil viscosity (10W-30 is explained here as an example): • The 10W in 10W-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 10W-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.
