Engine Oil and Filter

Checking
Check the engine oil a couple of minutes after shutting the engine
off, with the car parked on level ground. Remove the dipstick and wipe it clean. Re-insert it all the way down, then pull it out and read
the level. The level should be between the upper and lower marks.

Adding
If the level has dropped close to the lower mark, add oil until it is
even with the upper mark.
1.Turn the oil filler cap counterclockwise to remove. Add oil, then check the level again. Do not overfill.
2. Reinstall the cap and twist clockwise until it stops.

CAUTION:
Be sure the oil filler cap is correctly replaced before starting the

engine.
Engine oil is a major factor affecting the performance and
service life of the engine, you should use only a premium quality
detergent oil labeled SG grade.
Some oil labels may also include additional designations of quality
such as CC or CD. However, these are acceptable only when used

together with SG.
