Oil Pressure Warning Light
Urgency: CriticalThe oil pressure warning light indicates that oil pressure has dropped to a dangerously low level. This is one of the most critical dashboard warnings. Low oil pressure means the engine is not being properly lubricated, which can cause rapid engine wear or complete engine failure. Common causes include low oil level, a failing oil pump, or a clogged oil filter.

When to See a Mechanic
Stop driving immediately. Check oil level first — if low, add oil. If the light stays on after adding oil, have the vehicle towed to a mechanic. Running an engine with low oil pressure can cause catastrophic damage.
