15W-40:
API grade SL, SM, SN or SN PLUS
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
0W-20, 5W-20 or 5W-30 engine oil
is recommended.
A Temperature range anticipated
before next oil change
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 tempera-
ture. An oil with a higher viscos-
ity (one with a higher value) may
9-1. Specifications
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.
A
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-Conserving"
means that the oil has fuel-saving and
environmental protection capabilities.
B ILSAC Certification Mark
The International Lubricant Specifica-
tion Advisory Committee (ILSAC) Certi-
fication Mark is displayed on the front of
the container.
