    Default Oil Pressure issue?

    Good evening folks, my first post related to my first Duramax engine.
    Information:

    2007 2500HD with the duramax engine
    6.6L engine says it on top of engine cover
    Original 26,000 miles on it
    On my way home I notice the oil pressure was low I think but don't know?
    Cold start 50/55PSI
    warm idle 30PSI
    30-60mph 35PSI
    60-70mph 35-40PSI
    80mph 40PSI

    Current history:
    The oil needs to be changed, the truck sat for months at a time only used in summer to pull large camper.
    Any advice related to proper oil pressure will be really appreciated. One last question, what brand oil and filter is a good one to stay with?
    Thanks to all, Steve
