High oil pressure
I just switched my oil to Royal Purple 10w-30 with a Mobil 1 filter. With the engine up to temp at idle the oil pressure is 25-30psi. Under boost it creeps up to about halfway between the 60-90psi marks.
Is this high of sustained pressure going to hurt anything? I tried searching around but I couldn't find much on high oil pressure, mostly low.

The stock OP gauge is known to be rather optimistic. Probably 20% high if you're looking for hard values.
Super's right. Watch for trends and only be alarmed if there is a sudden, large difference between expected trend values and actual values.

Ok good to hear. It is acting exactly the same just at a higher pressure. Usually right after an oil change the pressure is 5psi or so higher than the old oil, but with the Royal Purple it's near 10-15 so I was freaking out. Thanks.
(Also, Royal Purple is actually purple oil...I was not expecting that.)

Everyone seems to love the OEM filters, so if you have low pressure I would run that. I tried to get some OEM filters but my local Mazda dealer isn't interested in helping me. I run Mobil 1 filters because it's either Fram or Mobil 1...easy choice.
