Engine Oil: Testing and Inspection
Inspection
1. Check the engine oil quality. Check the oil deterioration, entry of water, discoloring of thinning. If the quality is visibly poor, replace the oil.
2. Check the 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 in 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.
