How can you check the engine oil level?

You correctly chose the sight-glass and the oil dipstick as ways to check the engine oil level. According to German traffic rules and vehicle maintenance guidelines, the engine oil level is typically checked using a dipstick or, in some vehicles, a sight-glass. The dipstick is a metal rod you pull out from the engine, wipe clean, reinsert, and then check the oil level against marked indicators. The sight-glass is a transparent window on the engine casing that shows the oil level directly. The instant fuel consumption display, on the other hand, relates to fuel efficiency and does not provide information about the engine oil level. Regularly checking the oil level ensures your engine runs smoothly and helps prevent damage.
