oil pressure

[Dave]

i have a 69 road runner with a 73 440 in it. when its cold the oil pressure is about 60 but when its warm and i come to a stop the pressure drops to about 15 does anybody know if this is normal?

 

[Basketcase]

sounds like normal range to me.

 

[Dave]

ok thanks basketcase

15 psi at warm idle is acceptable. I think the low oil pressure light comes on at 7 psi IIRC.

Yep your fine

that's ok

I wonder if my gauge is messed up. It's usually says 70. I just replumbed it to copper. Still says the same thing.

At what RPM

 

[Smokngun]

"Rule of thumb" for oil pressure is minimum 10 psi for every 1000 RPM of engine speed.

its the oil too! thicker oil more psi---the engine was made for sae 30 not muti- 10w--30wt it ok
