- The "Full" line indicates the ideal oil level.
- The "Add" line indicates the minimum oil level.
The oil level should be checked regularly, and topped up as needed to keep it between the "Full" and "Add" lines.
Note: If the oil level on the dipstick is above the 'Full' mark, it means that the engine is overfilled. This can cause damage to the engine, and should be corrected immediately.
