Title: Oil pressure
Post by: Shimy87 on April 17 2021, 07:59:34 PM

Just curious, what pressure do you guys see at warm idle and cruise?

Depends on what oil, which car, ambient temperature... but I see 15 on one car and 20 on the other in the summer time at idle.  Idle pressure is not very important because there is no load on the engine so I would say anything above 10 is fine as long as it comes up quickly with increased throttle.

At cruise, it varies as well, but,  40-45 on really hot days after I have been driving 30 minutes or so at cruise (75mph).
