I could swear my oil pressure is very slowly dropping over time, now at ~35psi cruising where it used to barley be over 40psi. Should I be worried? I'm hoping I'm just being paranoid, its a stock 96k mile bottom end. I got it up to 4k rpm's to to see the oil pressure and it was still under 40psi.

 

add in some lucas oil on your next change, i have a 145k stock bottom end, and the oil pressure had increased with the stabalizer added

 

i wouldnt use lucas. heres why http://www.bobistheoilguy.com/images/lucas/lucas.htm

 

Could be your oil is a bit too thin---switch to 10W-40 Dino Oil (good quality) and see if it brings your pressure up a bit.JMHO

 

Whenever I get my oil (and filter) changed, the pressure goes back up by a few PSI. Maybe that's all you need?

 

What was the ending to this story? Rebuild or just new oil?

Cars still running, its actually running stronger than ever. I guess I just got the oil hot somehow and thats why the pressure showed lower than normal. Its about ~20-22 idle, and 38-40 cruising hot.

 

Mine runs about that hot, but what about WOT? Thats when mine seems to stay the same, I'm thinking its the cheap oil I'm using the break in the cam..

I haven't looked at the oil pressure at 6k+ rpm's Ill try to next time I drive it. I'm running 5w30 Mobil 1 btw.

 

I get 18 at idle when its warmed up. I went to a little thicker oil and it helped some.
