15psi idle oil pressure ok??
Searched, found varied responses dating back a couple years. Wanted to see if there had been some closure to this topic. Nissan dealership did my oil change, can't remember if this was the way I got it off the lot. Engine has 4500 miles on it.
Thanks
Thanks

Brand new synthetic oils [with brand new filter] will have the lowest idle pressure at warmest temperature.........conventional oil thickens with hours of use, as the lightest parts [molecules] evaporate 10-20% depending on brand.
Thus idle oil pressure will vary alot but shouldn't go below FSM minimum even after hours of hot idling in traffic, if it does you need somrthing thicker.

Low Oil pressure
So I just started to notice my oil pressure get a little low when at operating temperature when idling. It has been sitting around 15 psi. I checked the dipstick oil level and it is at the high mark (I checked after car was sitting for about 2 or 3 hours) Is this something I should be worried about?

I was just curious because for the first 3 weeks that I had the car...the oil pressure was always around 30 psi when idling and at operating temperature. Sorry if it is a stupid question...I'm just trying to understand and learn by researching and asking questions.

I have noticed that I just having same issue after changed oil.
I am also 15 psi at idle, and around 115 psi at pull hard.
The shop put the oil almost full, which is at the "H" line.
Is this can be cause the oil pressure problem?
