öljymäärää
Öljymäärää refers to the quantity of oil present in a system, most commonly within an engine. This is a critical parameter for the proper functioning and longevity of mechanical components. The correct oil level ensures that moving parts are adequately lubricated, preventing excessive friction and wear. Too little oil can lead to overheating and severe damage due to insufficient lubrication. Conversely, an overfilled engine can also cause problems, such as increased internal pressure, foaming of the oil which reduces its lubricating properties, and potential damage to seals and gaskets.
In most vehicles, the oil level is checked using a dipstick. This is a metal rod, usually
