Mine is up that high, I haven't had any issues and nobody really ever says anything about it.

The stock gauges aren't exactly good at measuring things though either.

at idle upon start up my 00 sits at around 60 psi. Once warm or once i start driving it's idle pressure is around 30-40 and driving is steady 60. If it suddenly jumped up to that after not being there before i would worry. Otherwise I would just check to see if your sending unit is giving you the right readings.

I would not worry too much about it because they have relief valve set to 75 psi, so it should be fine...

You're fine. Oil pressure is good, NO oil pressure is bad.


I'm told if the oil pressure spikes, and by spikes I mean SPIKES, that you might have a clogged, clogging oil filter. Dunno for sure, maybe someone else can explain that one.

But you're fine where you are.
