RED oil pressure light = ENGINE EMERGENCY. PULL OVER IMMEDIATELY AND SHUT OFF ENGINE. Do not drive even one more mile. Why: no oil pressure means bearings and journals are dry. Within 30-60 seconds of no oil pressure, severe engine damage occurs. 1) Check oil level — add oil if low. 2) If level fine: oil pump failure, oil passage blockage, pressure sensor failure. 3) Start engine for 5 seconds — if light goes out, may be faulty sensor. 4) If light stays on with full oil: tow to shop. Running an engine with no oil pressure = guaranteed engine rebuild.
