Call any authorized Lexus dealer or repairer, or another duly qualified and
equipped professional, service station or auto parts store for information con-
cerning recycling or disposal.
Do not leave used engine oil within the reach of children.

Engine oil selection
“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:
0W-20, 5W-20, 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):
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 avail-
able, 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.
