Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Toyota
recommends the use of approved “Toyota Genuine Motor Oil”.
Another motor oil of matching quality can also be used.
Oil grade:
0W-16:
API grade SN “Resource-Conserving”, SN PLUS “Resource-Con-
serving” or SP “Resource-Conserving”; or ILSAC GF-6B multigrade
engine oil
0W-20 and 5W-30:
API grade SM “Energy-Conserving”, SN “Resource-Conserving”,
SN PLUS “Resource-Conserving” or SP “Resource-Conserving”; or
ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-16 is filled into your
Toyota vehicle at manufactur-
ing, and the best choice for
good fuel economy and good
starting in cold weather.
If SAE 0W-16 oil is not avail-
able, SAE 0W-20 oil may be
used. However, it should be
replaced with SAE 0W-16 at the
next oil change.

Engine oil selection
“Toyota Genuine Motor Oil” is used in your Toyota vehicle. Use
Toyota approved “Toyota Genuine Motor Oil” or equivalent to satisfy
the following grade and viscosity.
Oil grade:
0W-20, 5W-20, 5W-30 and 10W-30:
API grade SL “Energy-Conserving”, SM “Energy-Conserving”, SN
“Resource-Conserving”, SN PLUS “Resource-Conserving” or SP
“Resource-Conserving”; or ILSAC GF-6A multigrade engine oil
Recommended viscosity (SAE):
SAE 0W-20 is filled into your
Toyota vehicle at manufactur-
ing, 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 0W-20, 5W-20
or 5W-30 engine oil is recom-
mended.
