Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace the oil.
Check engine oil level.
After warming up the engine and then 5 minutes after the engine stops, oil level should be between the "L" and "F" marks on the dipstick.
If low, check for leakage and add oil up to the "F" mark.
Do not fill with engine oil above the "F" mark.
Recommendation (except Middle East) : 5W-20/GF4&SM (If not available, refer to the recommended API or ILSAC classification and SAE viscosity number.)
API classification : SL, SM or above
ILSAC classification : GF3, GF4 or above
SAE viscosity grade : Refer to the recommended SAE viscosity number.
For best performance and maximum protection of all types of operation, select only those lubricants which :
Satisfy the requirement of the API or ILSAC classification.
Have proper SAE grade number for expected ambient temperature range.
Lubricants that do not have both an SAE grade number and API or ILSAC service classification on the container should not be used.
