■Engine oil selection
“Toyota Genuine Motor Oil” is used in your Lexus vehicle. Lexus recom-
mends the use of approved “Toyota Genuine Motor Oil”. Another motor oil of
matching quality can also be used.
Oil grade:
0W-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:
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 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.
