Re: Oil Cap and Dip Stick

Come to think of it, the minimum oil level is determined by the airframe manufacturer.

TMI:
The minimum usable quantity is calculated by combining the absolute safe operational minimum* with the engine's maximum allowable oil consumption rate multiplied by the aircraft's total fuel endurance.

*The absolute safe operational minimum is the minimum amount of oil needed for proper lubrication and cooling without causing oil pressure loss, air ingestion, or temperature spikes.
