While driving my 05 in 65 degree temp at legal speeds I noticed my oil pressure was sitting @ 35 lbs...normally its at 40 lbs. The car has 22,000+ miles showing and runs like a new car.
Is this normal? Just had an oil change, Mobil 1 5-30 two weeks ago.

Any comments will be appreciated.

What was the outside temperature when you were seeing 40 lbs (i.e., warmer , colder, or about the same)? All other things being equal, cooler temps should result in higher oil pressure. That said, I don't think 35 lbs is cause for concern on a warmed-up engine.

You don't have a Problem!! Oil pressure should run 22-45 lb's!!! The old timers clam,8-10 lb per 1000 rpm's!!! Some of the older engines need at least 10-14 just to keep the Hydraulic lifters pumped up!!! I've seen my C-5 as low as 28-32 Idling on a Hot,Hot day in heavy stop and go traffic!! It has 34,000 on it!!:upthumbs

Thanks guys. I recently built a very stout 383 stroker for my adult son and we put it in an El Camino. It runs about 65 PSI consistently (also runs low 12s) I am always comparing the El Camino to my other cars.
