■Adding the engine oil
If the oil level is below or near the low
level mark, add engine oil of the same
type as already in the engine.
Make sure to check the oil type and prepare the items needed before adding.
Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Return the filler cap and turn the ca
p clockwise until you hear a
click.
It takes about 1.6 qt. (1.5 L, 1.3 lmp.qt.) to raise the oil level from low to full on the
dipstick.
■ Recommended viscosity
Temperature range anticipated before next oil change.
SAE 5W-30 is the best choice for
goo
d fuel economy, and good starting
in cold weather.
If SAE 5W-30 is not available, SAE
1
0W-30 may be used. However, it
should be replaced with 5W-30 at
the next oil change.

*5W-30 is an oil that provides optimal levels of fuel efficiency
Oil viscosity
• “5W” oils are for use in ar
eas where the ambient temperature is -13 F (-
25 C) or above. “10W” oils are fo r areas where the ambient tempera -
ture is -4 F (-
20C) or above. Oils with smaller figures are better for
engine starting in cold we ather and fuel efficiency.
• “XX-30” indicates oil viscosity. O ils with lar
ger figures have better ther-
mostability and are good for high-speed driving.
