Low oil pressure

[Duduglanza]

Hi , im getting low oil pressure on idle.. 15/18psi when fully warm. Im a bit worried and i don't know much was this problem going on as i installed the aem oil pressure gauge few months ago and was always like this since then.

Changed the oil relief valve but still same readings.

Should I replace the pump for safety or can i add some washers in the oil relief valve just to increase the pressure by few psi?

Anyone did this procedure?

The main thing that affects oil pressure is the bearings and large oil clearances.id drop the sump and look at the bearings. If okay change the pump. Shinning valve is a bit of a bodge

Think your car has cought the same bug as mine haha

Wouldn't I be right in saying the hotter the oil temp, the Lower the oil pressure goes? When I been sitting in heavy traffic in the past on hot days, and the oil temp go above 90 degrees I find my oil pressure goes down aswell, but normal all other times.

That pressure is fine for idle.

That's not low oil pressure.

Tought that below 20psi is a bit risky :/

Someone before said Toyota recommend no lower than 7psi on warm idle

[patman]

That's what they recommend yes Craig although 7psi I think is living a bit on the edge, and I think yours if fine duduglanza, just keep an eye on it 👍🏻

1 bar / 14.5 psi is the lowest I'd like to see, any lower and really there's an issue.
