As long as you have enough pressure to keep the HPOP in oil then it will run.

The instrument cluster gauge sensor is behind the oil filter and is about useless, it only reads 7 psi. The hpoil system sensor is on the front passenger valve cover and can only be read by a monitor device or a scanner. 500 psi min. to start. The low pressure system can only be read accureately by a mechanical test gauge thru a port on the bottom front of the oil filter houseing. 45 psi min.

I had similar issue after switching to syn. 5W-40. No oil preasure reported sometimes going 75mph too. Replaced oil pressure sensor fixed it. My sensor
wire leads were covered in oil too.

I would verify (by a real gauge) your oil pressure.

Anything above 7psi and your idiot dash gauge will read in the mid normal range on the dash. Anything below 7psi will cause the dash gauge to read at the bottom of the scale and trigger a light.

I actually have a real Autometer Oil Pressure gauge and read it from the top of my billet aluminum cap.

My readings with oil temp at 190* are:

Idle = 20 PSI with 10W-30 and 22 with 15W-40 or 5W-40.

Running down the highway: 56 PSI 10W-30, and 58PSI with 15W-40 and 5W-40
