Low oil pressure?

Low oil pressure?
Just picked up a 89 t2 and noticed that the oil pressure on the hwy hangs around 30psi. Haven't been in the scene in a few years just curious what could cause this issue. I will check the sending unit tomorrow but if it is gd that's too low as I recall. No problems from car.

Will look into it. Just went out and sprayed carb cleaner on the sender and clip. Coated in oil. 30 psi warm at idle. I don't know why I bought another rx7?! lol I know the oil cooler lines are leaking a lil. Not bad but they are leaking. Ordered a new set of mazdatrix lines. Car was tuned at rotary performance before I bought it 2 months ago.

For kinda reference or comparison, I hooked up an AEM oil pressure gauge and my pressure is typically around 70 psi; factory cluster gauge indicates around 40 psi. I thought 70 psi seemed high and checked the FSM. Going by memory the FSM indicated something like 68-73 psi is typical for a NA (I have a 90 convertible).

Well I notice that while the car is warming up the pressure is a solid 40-60 and fluctuates with any throtlle input. Its when driving down the hwy it resorts back to showing 30 psi-40 psi. Really weird. I think the diaphram on the Oil sender is shot.
