Oil pressure real low, common problem with pressure gauges?
I got the FD back out of storage, and the oil pressure is real low at idle (like not at zero, but below the first tick mark above zero at idle. It'll go near 60 if I just rev it to 3500 or so though.. really weird.

The sender has a metal part that holds a small spring . that part wears out ,thus sending a low signal to the gauge . First clean the wire connector on the sender , if that does not work replace the sender unit .

It's southwest of the oil filter (if the 3rd gens are anything like 2nd gens). And if they're similar design, it looks like a big bell sticking out of the side of your engine.
It's funny, I never had any problems with my FC's oil sending unit, it worked like a charm.

South west of the oil filter, yes find the oil filter on thedrivers side of the engine toward the bacs . the sender is 3-4 inches below and 1-2 inches forward. It may have a black rubber cover and has a one wire connector . It is about 2 - 2.5 inches in diameter .That means look down from the oil filter Southwest .

lol, oil change won't work. It's just the sender.
Just clean it and it should be ok, if not, then just replace.
Sometimes I just hate mazda for the half *** jobs they did when adding parts to the car.

Hey,
Just want to thank you all for the answer. I just got my car running and have the same concern. My only other concern is that cold, the pressure is 60+ psi but after warming up, it drops considerably.

I had the same/similar problem: oil pressure was fine when the revs were up, but at idle the pressure was very low or sometimes zero on the gauge, it seemed to be worse on hot days. I cleaned the connection on the oil pressure sender unit and it helped a little, temporarily. Finally put in a new OEM sender unit and the oil pressure reading has been normal - very comforting.
Bought my oil pressure sender from Mazdaformance (http://www.mazdaformance.com) for $71 - p.n. N3A1-14-820.
(Yes it is a late post, just contributing my 2 cents.)
