[DeTomaso] Oil pressure drop

My car was doing this last month.  I checked the oil pressure directly at the block and the pressure was 65 idle and 70 WOT and never dropped.  It turned out to be a failing oil pressure sending unit.
A week or so later it went out and read zero on the dash gauge as I had not gotten around to installing the new sending unit which is 9 bucks at Advance auto.

Have you checked the oil pressure with a direct gauge on the back of the block?

> Funny thing I noticed...... Oil pressure drops while driving at higher rpm ... I wind the Cleveland up in rpm as it gets to 4500 the oil pressure gauge drops low ..like to 10. No noises or rattle. It has been running around 45- 70. I am using multi weight Rotilla with a quart of Moray's oil conditioner, kinda like high tach. I checked the oil and it is even with the low mark. I added a quart and have not been back out. NO way I'm pumping 5 1/2 quarts up and lowering the pan level?  Could it be too thick?
