Morphology
The meaning 'the pressure of oil circulating in engine parts' is directly and compositionally derived from 'oil' (a lubricating liquid) + 'pressure' (force exerted), forming a standard noun+noun technical compound. While the full technical implications (engine lubrication) require domain knowledge, the basic concept is transparent and cross-linguistically regular, so a B1 learner who knows both words will grasp the main meaning.
Etymology
Oil pressure names the force that pushes oil through an engine's moving parts, so imagine oil like the engine's blood being forced into tiny spaces to keep parts moving smoothly. That's why low oil pressure or a 'warning light' means the engine is not getting the 'lubrication' it needs and can be damaged.
