Default What's your Oil Psi after warming up (idle/driving)?

Trying to see if my 2.3L in my Ranger is getting good oil psi.


When I first crank it up (without it being warm) it goes to 50+ or so psi and then after it warms up it drops (oil gets warmed up) and it goes to 25 psi +/- when idling. I guess that's good?

Just got a new oil pump.


What's yall oil psi idling and driving?

That sounds about right

My Jeep 4.0L runs at 18psi at idle (warm) and 40-60 when under load


My ranger doesn't have #'s on the gauge, but it goes up to 3/4 when cold, at idle warm its around 1/4 up the gauge, and cruising its in the middlee-to 3/4 up

As long as the motion of the gauge is right I would call it good

Well I'm going to see if I can make it to alignment shop tomorrow so they can align my steering on it. All of my tires are badly dryrotted. Front tires are really worn but showing no wires. The two rear ones leak air and one needs air in it maybe it won't be flat in the morning. Maybe I can drive 38 miles to the alignment shop and drive back.

Wish the best for me.

I don't feel like breaking down on the way to work...

Engine seems fine, can't check the oil cause I need a new dipstick tube, had to use the old dipstick tube that came with this 2.3 (but can't let me check the oil cause of the rear sump). Just did an oil change on it so it should have enough oil. Just pour some coolant in the radiator too.

my 4.0 runs around 60-65 when cold. after warm up it runs around 30-32, driving in 5th gear at 65 it runs around 40.

Mechanic told me that Ford pioneered the "idiot gage" on the Ranger. Not sure what model(s). They got tired of customers complaining about oil pressure readings and switched to a sender that was simply a pressure switch coupled to a gage that read 2/3 scale when the switch was closed. End of complaints.

Hmm.. That would make sense. On my '95 Ranger the oil pressure on the gauge doesn't seem to change whether it's warm or cold. Just at the half way mark. Which wouldn't seem to make sense - since a hot motor at idle should have fairly low pressure.
