How can you check the engine oil level?

You answered correctly. To check the engine oil level, you can use either the sight-glass or the oil dipstick. The sight-glass is a transparent window on some engines, allowing you to visually check the oil level. The oil dipstick is a marked stick that you pull out, wipe, reinsert, and then pull out again to see the oil level between the minimum and maximum markers. The instant fuel consumption display, however, only provides information about how much fuel the car is currently using and has nothing to do with measuring oil level. Knowing how to correctly check oil is important for engine health and to prevent engine damage.
