Engine Oil: Testing and Inspection
INSPECTION
1. Park the vehicle on a level surface.
2. Remove the oil level gauge and wipe it clean.
3. Reinsert the level gauge all the way. Be sure that the level gauge is correctly inserted and properly orientated.
4. Remove it again and check the engine oil level. If the engine oil level is below "L" line, add oil to bring the level up to "F" line.
5. After turning off the engine, wait a few minutes for the oil to return to the oil pan before checking the level.
6. Just after driving or while the engine is warm, engine oil level show in the range between "F" line and the notch mark. This is caused by thermal
expansion of the engine oil.
NOTE: To prevent overfilling the engine oil, do not add oil above "F" line when the engine is cold.
