whats with my oil pressure

ok I just changed the oil in my car and for some reason the oil pressure gauge will come close to maxing out at anything above 3000 rpms
at 2000 it will stay near 60 psi usually just right at or a tad below at 2000 rpms also it is slower to come down now that I changed the oil
this is the first time it did this in the two years I owned the car.

once I had it go past the 110 marking on the gague by prolly a 1/8 inch or so


I am using 10w-30 oil right now
was using 20w-50
also using a fram oil filter

the oil is a little high right now though
I think it is at the top of the F on the dipstick and that is the only thing I am thinking of as to why the pressure reads so high

is there any harm that could come from the oil pressure reading so high and any ideas as to what is causing this and how to fix it?

Well, unless it stays cool (always below 80 degrees F) where you live, I would recommend keeping your car full of 20w-40 or 50 as 10w-30 is a little thin for a rotary engine. Secondly, Fram filters aren't what they used to be, you might want to look into a better filter if you can find one. You might want to avoid driving the car until the problem is resolved, you don't want to risk breaking something expensive, so i suggest filling it back up with 20w-40 or 50 and seeing what happens from there.

well it does get hot here I admit that... well hotter then normal
I have used 10w-30 most the time I owned the car as well as the previous owner with no problems in . I went to 20w-50 just out of curiousity and I honestly think I am going to switch back on the new oil change.

fram well I heard they are not like what they used to be but I needed to get the oil changed bad and fram was only thing there and was cheap enough for me with my unemployed *** to get.

what oil filter would you say I should get for my car?


it is still drivable I just keep the revs down so the oil pressure doesn´t go up

Mobil 1 oil filter or OEM filter. This was brought up yesterday. I also used fram but did some research and found it isn't what it used to be. Good luck to ya!

Verify oil pressure with a mechanical guage. The stock sender and guage is not that great. Also, use a thicker oil. The rotary heats up (and thus thins) oil much more than a piston engine.

don´t have access to a mech oil gauge

though a gauge shouldn´t be that far out of wack just by one oil change and maybe 15 min should it?

you can have oil and engine failure using 10W30 in temps above 80F. Viscosity breakdown could be the reason for the high reading.
