IR P185WIR & XP185WIR Troubleshooting: Engine Oil Pressure Lamp Stays On
If the oil pressure warning lamp stays on in your Ingersoll Rand P185WIR or XP185WIR, stop and investigate immediately. Low oil pressure is one of the fastest ways to cause serious engine damage—and catching it early can save you from a major overhaul. Here's where to start troubleshooting.
Common Causes of Oil Pressure Lamp Staying On
- Low oil level: If oil levels are too low, the system can’t maintain proper pressure, triggering the warning light.
- Compressor out of level (>15 degrees): When your unit isn't level, oil pickup may be compromised, leading to false low-pressure signals.
- Wrong lube oil: Using oil with the wrong viscosity or type can prevent the oil pump from building enough pressure, especially in extreme temperatures.
- Engine malfunctioning: Internal wear, failing oil pumps, or bearing problems inside the engine can cause genuine low-pressure conditions.
Recommended Fixes
- Check oil level and top off with the correct compressor oil if low.
- Verify that the compressor is operating on level ground within 15 degrees side-to-side and front-to-back.
- Drain and refill with proper oil if incorrect lube oil was used.
- If oil level and type are correct, and the unit is level, a deeper engine inspection is needed to check for worn components or a failing oil pump.
Wrap-Up
The oil pressure lamp isn’t something to ignore. Quick action can mean the difference between a simple fix and catastrophic engine failure. Stay on top of oil checks and maintenance to keep your P185WIR or XP185WIR running strong for years to come.
