Oil Filters?
 

Can different oil filters change oil pressure? I've been using Mobil One 10 W 30 all along
I've been running regular Neon oil filters (napa gold). Someone gave me a case of Mopar perfomance V 10 Viper oil filters. (Yes they fit fine).
The neon filter is tiny holds less than a pint. The Viper filter is normal car sized.
I've noticed a drop in oil pressure with the motor hot. Changed oil pumps and rod bearings. Started it up today and it still seems low for the motor temp.
I'm probably going to go out tomorrow and buy a neon filter to see if it makes a difference.
I'm also going to change to Valvoline racing oil 10 w 30 (after I try the little filter)
I'm just wondering if the Viper filter is filtering the oil better. Thus lowering the pressure at an idle. I still have plenty, but I just don't like the drop without knowing why it dropped.
I know that some of the filters come with paper elements. But I doubt Mopar Performance would be using them.

Yes.

Agree completely had a 68 GTX 50 pounds oil pressure wix filter changed oil and filter fram 5 days later 0 oil pressure filter paper in oil pump and passages DO NOT USE FRAM!

Wix Racing filter the BEST !!!

My filter is positioned after the pump.

Art, yes a filter can affect oil pressure. The differance's in the filtering elements can either cause more or less of a restriction and in turn drop or raise oil pressure. I have seen over 10 psi change from differant filters

Artie,
The Viper filter is one of the best, has a low restriction element with a high burst canister. It will result in a lower pressure reading at idle but it has a higher flow rate cause at high rpm's.
There are several part numbers available and one of them had some issues, will have to check.

Not positive but I seem to think that the P4529190 filter has a bypass of like 8-10 PSI and a flow rate of 28-30 GPM vs. the "stock type " Neon filter which has a bypass of like 25-30 PSI and a flow rate of only 7-9 GPM--probably why the pressure is coming up so low----less restricton and more oil flowing(volume) ---put a wix 51515R on it and see what happens they are really the way to go---otherwise put a Peterson in line filter on the inner fender but then you hafta run braided line and all----FED387

Hi John the part number is 05281090

I just found out what the problem was with my "lower" oil pressure.
I updated the firmware in my ECU yesterday. And wanted to check the functions, datalogging ETC. I dataloged it for about 5 minutes. And when I went over the data I found that my idle was almost 200 rpms lower (850 rpms opposed to 1,050).
This didn't show on the tach. I had worked hard to get the idle smoother over the winter, but the tach didn't show the difference.
When I raise the rpms to 1050 it's the same as last year. The oil filter didn't make a difference (tried a regular filter just to be sure)
