Okay stupid question but a 5.0 holds 5qts. Of oil right? I always empty both drain plugs and the oil filter completely and add 5 qts. And I always seem to have high oil pressure

Maybe that will help?

 

What viscosity oil are you running?

The volume of oil in the pan shouldn't effect oil pressure unless its low. The oil pump ultimately determines oil pressure which can be effected by the state of the engine (worn engine components, quality of of oil system, et al).

Another component that can effect oil pressure is the bypass in the system. If the bypass doesn't open at the correct pressure then the oil system will operate at a higher pressure.

Beyond that, all I can think of is a faulty sensor.

 

I run 10W 30 Royal Purple and I think when I bought her the previous owner may have mentioned a high volume oil pump

 

Sounds like it was on purpose but from what I read, high oil pressure is very bad!

 

It's not crazy high, it reads between the 'm' and the 'a' on 'normal' I was just wondering about it. Thank you for the link, it really explained a lot

 

Something like that?
Np glad it helped.
