To understand oil level dropping between services, compare it under normal, safe conditions: cold versus warm, idle versus steady speed, and light versus higher load. Measure on level ground using the maker’s specified waiting period and log each reading. Change one condition at a time so the result stays useful.
Do not create a risky test just to reproduce it. Look for external leaks and note smoke or recent oil work; consumption rates vary by engine.
