Lately, I have been noticing my oil pressure has been running about 3/4 gauge. That just seems awful high. Runs alittle higher cold. I'm pretty sure there is no coolant getting in there since I have not found any traces in my oil changes.

 

Not sure but I am farily certian mine reads about 3/4 most of the time when driving. At idle it is about half or so. In my Vette is is 40psi idle and 60 or so.

My T/A usually ran about lil over half gauge but after the better oil pump it ran at 3/4 cruising all the time.

 

My Tahoe sits about 3/4 most of the time and a little over when I'm hard on it. My truck is more in the typical just past 1/2 range.

 

Well I remember it use to sit at about 1/2 all the time. Hmmmm guess the engine is getting better. LOL!!

 

Or it's time for an oil change. LOL

 

did you change to a thicker oil?

 

Never seen anything but Mobil1 10w30. Less than 2k on this change.

 

mine went higher when my rings blew out. i guess the added pressure being added into the crankcase didnt help

 

Mine has always ran about 60 psi, but has been a little higher than that. On the 2000 Z-71 it runs about 40-50 psi (110k miles on it).
