What lights will show if oil pressure remains between 15-40 psi at IDLE for 5 seconds or more?

When oil pressure falls between 15-40 psi while the engine is at idle for a duration of 5 seconds or more, it triggers both the red and amber "OIL PX" lights to illuminate. The amber light serves as a warning that the oil pressure is lower than the optimal operational range, indicating a potential issue that requires attention but may not be immediately dangerous. The red light, on the other hand, signifies a more critical condition, indicating that the oil pressure is unsafe and may lead to engine damage if not addressed immediately.

This dual-light indicator system is designed to alert the operator to escalating concerns regarding oil pressure. The presence of both lights reflects the severity of the situation and stresses the importance of checking and addressing oil pressure issues promptly to ensure the continued safe operation of the vehicle or aircraft.
