Make sure to check the oil type and prepare the items needed before
adding oil. Remove the oil filler cap.
Add engine oil slowly, checking the dipstick.
Install the filler cap, turning it clockwise.
The approximate quantity of oil needed to raise the level from low to full on
the dipstick is indicated as follows:
1.6 qt. (1.5 L, 1.3 lmp. qt.)
■ Recommended viscosity
SAE 5W-20 or 0W-20
SAE 5W-20 or 0W-20 engine oil
may be used. However, SAE 0W-
20 is the best choice for good fuel
economy, and good starting in
cold weather.
