Oil pressure: Don't trust your dash light!
The AEM Digital 0-100PSI Oil Pressure Gauge allows you to monitor pressure to 100PSI on an easy to read gauge.
Aside from air/fuel, oil pressure is one of the most critical things to know in an engine. At high RPM, lower than acceptable oil pressures won’t trip the low oil pressure light on the dash, resulting in damage to bearings – or worse!
Now you can know if your pressure has started to drop before real damage can occur. The needle style gauge is easy to read at a glance and also makes it easy to see when oil pressure changes out of the corner of your eye.
- Comes with white and black faceplates and silver and black bezels
- Analog display ranges from 0-100PSI in 2 PSI increments
- 0-5v output for engine management/data logging
- Standard 52mm (2 1/16”) size for easy installation
- 100 PSIg brass sensor included
The top three gauges for a BMW are Water Temp, Oil Temp and Oil Pressure.
Some BMWs have a Temp Gauge; while Oil pressure is usually left to an “idiot light” on the dash that warns when oil pressure drops below a certain threshold, but one that at high rpm can still allow damage to the bearings, or much worse.We have seen slight over-revs result in a stretched rod bolt that allowed the bearing to rotate, and this dropped the oil pressure by a few PSI the following lap. That difference did not set off anything other than some curiosity in the driver as to why the car was making 10PSI less oil pressure than the previous laps, causing him to pull in and thus save the motor from windowing the block. Enough said on an expensive BMW motor.
