Question: Oil pressure goes back up after oil/filter change?

[ALLY Fox]

The last time I changed my oil I used Mobil Delvac and a genuine Delco oil filter (I think I had a Fram filter on it before I changed it) I noticed my oil pressure was lower while driving, about 45 at highway speed vs 55-60 prior to changing. I didn't worry too much about it but it seemed strange. Yesterday when I changed oil and filter, I used Mobil Delvac and a Mobil M1-303 filter and my oil pressure is back to where it was, 60 at highway speed and engine is definitely quieter. Can anybody tell me why the Delco filter would seem to cause lower oil pressure? Anybody else experience this?

Crappy filter? Or better filter element?

I know delco stuff is not the level it used to be, I run wix/napa gold on my truck.

How do you know? I usually run the Delco but sometimes Fram.

Mobil M1-303 is supposed to be one of the best filters you can use on a Duramax, I think I would have to agree although I'm not entirely convinced that higher oil pressure means it's a better filter.

I wouldn't trust a fram on a weed eater!

I agree and wouldn't use a fram filter.

I would have to say that 99.9% of us on this forum go over board on filtration. Cheap insurance.

What made you guys hate Fram…is there an article to read about them?

Fram uses paper ends on their elements I have cut a few open and found the ends separated from the element providing no filtration what so ever...

Wow. What are the best filters to run now days if the Delcos are getting worse? The Mobile M1-303 like Ally Fox said?

Just from what mechanic friend has mentioned to me, and of course, the all knowing internet forum jockeys. Apparently ACDelco was prior to bankruptcy and now the AC-Delco is not the same quality of original stuff prior. Do I have proof? No, but again, I run Wix/Napa gold stuff anywho.

Anyone have experience with the Baldwin oil filters? I usually run those.

I run Baldwin Oil and fuel filters on both my Duramax.

I'd rather use a sock than a fram "filter"
