Morphology
The meaning 'oil used to lubricate an engine' is directly derivable from combining 'motor' (engine) and 'oil' (lubricant); the compound simply names the oil associated with a motor. This noun‑noun composition is a common, compositional pattern found across languages, so a B1 learner who knows both constituents will readily understand it.
Etymology
Motor oil is a simple name: it is the oil used in a motor, or 'engine', to keep metal parts from rubbing together and to help them move smoothly. That's why the phrase means the oil that helps a vehicle's engine run well.
