Observed Oil Pressure with a gauge

40 to 332

Here's my input:

Gauge: Defi Red Racer 0 - 1,000 kPa (0 - 140 psi)
Sensor Location: On oil filter sandwich adapter plate (non-thermostatic)
Oil Cooler: None
Oil: Nissan Genuine Ester Oil 5W-30

Cold start - ambient temp. 27C (80F)
Initial reading: 760 kPa (108 psi)
After 1 minute: 500 kPa (71 psi)
After 2 minutes: 390 kPa (56 psi)
After 3 minutes: 340 kPa (49 psi)

Oil temp. 80C (180F)
Idle (no load): 190 kPa (27 psi)
1000 rpm (no load): 270 kPa (39 psi)
2000 rpm (no load): 440 kPa (63 psi)
3000 rpm (no load): 700 kPa (100 psi)

Oil temp. 92C (198F)
Idle (no load): 140 kPa (20 psi)
2000 rpm (3rd gear): 380 kPa (54 psi)
3000 rpm (3rd gear): 600 kPa (86 psi)

FYI: FSM lists oil pressure specs as follows:
Oil temp. 80C (180F)
Idle (no load): more than 98 kPa (14 psi)
2000 rpm (no load): more than 294 kPa (42 psi)
