How can you check the engine oil level?

To check the engine oil level, you should use both the sight-glass and the oil dipstick. The sight-glass provides a quick visual indication of the oil level, allowing you to see if it is within the acceptable range. The oil dipstick, on the other hand, offers a more accurate reading and can help you assess both the quantity and condition of the oil.

In Germany, it is important to regularly check the engine oil level as part of vehicle maintenance to ensure optimal engine performance and to prevent potential damage. Not using both methods might lead to an inaccurate assessment of the oil level, which can have legal implications in case of a vehicle malfunction caused by insufficient oil. Proper vehicle maintenance is outlined in the German Straßenverkehrs-Zulassungs-Ordnung, which mandates that vehicles must be maintained to a roadworthy standard.
