Oil Supply/Oil Level Measurement

Oil Supply/Oil Level Measurement







The oil supply system as a whole has been adopted from the previous model. A change was made in the area of oil level measurement. Continuing with positive experiences with electrical oil level measurement and a changing trend in measuring engine oil levels; away from manual checking via the oil dipstick to electrical oil level measurement, the new 3.6 and 3.8 liter engines do not have an oil dipstick.

In order to speed up the process of measuring the oil level in certain operating states and in the interests of measuring convenience, map compensation has been introduced. Previously, all of the engine oil had to return to the oil pan after the engine was shut off before the oil level could be measured. To enable accurate measurement of the oil level, the necessary time required to achieve this state was ensured by means of a waiting time for oil level measurement, determined according to the oil temperature and the length of time the engine has been off.

With map compensation, the actual measured oil level in the oil pan is compensated to take in account the oil temperature and the length of time the engine has been off. The oil that has not yet returned to the oil pan is electronically calculated and duly added, and the real oil level is displayed as quickly as possible in the instrument cluster. This results in a substantial reduction in measuring times compared with the previous system.
