    he DID answer 1 of your questions MIL
    Doesn't matter about brands of oil or filter.
    Hook up a mechanical guage and see what kind of pressure you have. Not sure where the sending unit is but try asking at www.ford-trucks.com

    What if he put 20w50 oil then decided switch back to 5w20 then tell us I have oil pressure issues.

    We been though this with several threads. If you check Ford Truck Enthusiast Forum. First people ask what oil weight and oil filter brand then use mechanical gauge.
