Recommended viscosity (SAE):
If you use SAE 10W-30 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.
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 vis-
cosity 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 con-
ditions.
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.
API Service Symbol
Top portion: “API SERVICE SN” means the

Lower portion: “Resource-Conserving”
means that the oil has fuel-saving and envi-
ronmental protection capabilities.
