Title: Oil Change-Higher Oil Pressure
Post by: Cyclone03 on June 25, 2018, 05:20:55 PM

I change the oil in my 433in FE yesterday,on start up leak check I noticed the oil pressure about 5psi higher.
I used a WIX filter for the first time,I usually use a K&N. Today after a complete warm up the pressure is higher ,about the same 5psi even at idle.
Is the filter restrictive and causing the pressure to indicate higher?
The other oddity was the water temp also running hotter,I have had stability at 215 at idle at 100*f air temp,today it went to 222*f. BTW that is AC on. With that I wonder if oil FLOW is suffering?

Last Friday it was just as hot,same drive,same long lights only the oil filter,with new oil was changed.

Well, I think you know what to do. Put on your K&N filter, pre-filled, and see what happens. And yes, a restriction can cause the pressure to change.

I went with the WIX because that seems to be the brand named here as very good.

I always see higher pressure after a change. That just means you filter is working at taking dirt out of the oil. If you are concerned, cut your k&N open & look at the pleats to see what is in there.
