Engine Oil: Testing and Inspection
INSPECTION1. Check engine oil quality.
Check the oil for deterioration, entry of water, discoloring or thinning.
If the quality is visibly poor, replace the oil.
2. Check engine oil level.
After warming up the engine and then 5 minutes after the engine stop, 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.
NOTE: Do not fill with engine oil above the F mark.
SELECTION OF ENGINE OIL
Recommended API classification: Above SJ or SL Recommended SAE viscosity grades: 5W-20
If 5W-20 engine oil is not available, 5W-30 or secondary recommended engine oil for corresponding temperature range can be used.
NOTE:
For best performance and maximum protection of all types of operation, select only those lubricants which
- Satisfy the requirement of the API classification.
- Have proper SAE grade number 1 expected ambient temperature range.
Lubricants that do not have both an SAE grade number and API service classification on the container should not be used.
