The oil pressure of my '90 Miata (96kmiles) at idle is 15. The highest pressure I see is around 30. Does this seem low to you?

Is that when the engine is warm or cold? If warm, that's on the low end of normal. If cold, that's a problem. My '90 used to run near 90 when cold and under acceleration, but near 20 or just above when warm at an idle.
When did you last change or check your oil?

When cold, it runs about 30psi at idle and 45 at rev.

First, clean the electrical connections at the oil pressure sender.

They are easy to get at, right next to the oil filter.

Leon, I hope that hole in your cheek heals quickly (you know, the one poked by your tongue).

No.
Mazda spec is 15-30psi (or 1-2 bar, if you have the Jap gauge) at

If that doesn't work, I'd change the sender unit or temporarily hook up a good mech. gauge.
