    Normal oil pressure after pulls?

    Just wanted to know, I have an 04 2.0L. I put redline 5w-30 about 400mi ago and when at normal idle I would run about 26-29 psi and after a couple pulls with my friends f250 I was sitting at 18-23 psi. Just wanting to know if it's normal to drop that low or if it isn't.

    Also 98k and pretty much stock, just an aftermarket topmount.

    I'd expect that to be OK. As the oil heats, the pressure will drop slightly. Idle pressure should be between 15 and 30 PSI. 30 PSI at cold start, and around 20 PSI fully warm. Remember that oil takes a lot longer than coolant to reach operating temps.

    EDIT: Some good info, >14 PSI at idle (fully warm) with the pressure relief at 85 PSI. Granted, this is an EJ257.

    yeah I see what you're saying. Also the oil temp hasn't gotten past 219 and the coolants highest temp was at 220. I just wasn't sure if it was a normal thing for the oil to become so thin that the pressure would drop that much lol thanks man! 👍

    Cold start can easily be as high as 90 psi+.

    Cold start in my car has always been over 100psi. When the oil is hot, 15-20psi is pretty normal. That was with 5w-40 T6, and an 11mm oil pump.

    Yeah cold is at 90-100 then after the oil temp gets to 200 (where it usually settles) then the pressure goes from 20-26psi and after running hard it goes to 16-20. Just wasn't sure but thanks for the replies guys! Helped out a bunch!
