What pressures are you seeing?
5 to 10 at hot idle
about 30 at 3000 rpm or so
motor "only" has 123k and runs fine
Recent oil change?
Fram filters have been known to do that.
Yep... that is low. Have you done an oil and filter change since first noticing it? I have seen significant differences in pressure when using different brands of filters... perhaps a bad filter would cause the really low reading?Quote:

no haven't changed oil
thinking of trying a WIX filter (have used them for years on other cars) and maybe 20-50
but don't think that will make any difference
92 58k miles, 626 wix filter, and a mix of greddy turbo oil and mobile 1. i see 30 - 32 hot idle and 50 - 55 at 3000rpm
That's what I used to see but after getting my motor back from John Day, my oil psi is normally around 15 at hot idle and only 30-40 max at 3k rpm when hot. Around 30 cold idle and 60 at 3k rpm when cold. I understand the oil sending units were not always calibrated the same making different Miatas read different but not the same unit changing after rebuild.:confused: Still using the same oil and such.Quote:

changed out sender and no change
installed mechanical gauge and it reads well within Mazda normal specs
dash gauge bad :D
Does that mean you have an extra, working sender? Cheap? ;) You have PMQuote:

You guys are lucky, my 96 has the stupid telltale. Only know of pressure problem after piston has gone into orbit.
Retrofit. I have a real OPG from a 94 on my car. Just swapped out the sender and gauge.Quote:
