oil for ford

my brother is wondering what kind of engine oil to put in his new to him motorhome. it is a 1993 ford 450 with the 460 motor gas. he has heard numerous suggestions but they all vary in the weights. does anyone know for sure?
thanking you in advance.
  • Per Ford:
    Engine oils with an SAE 10W-30 viscosity are
    PREFERRED for your vehicle which provide the
    best engine protection for all climates down to
    -5°F (-20°C). SAE 5W-30 enigne oils may also be
    used down to -15°F (-25°C).
    Synthetic engine oils which are CERTIFIED and
    of the preferred viscosity may be used in your
    engine. The engine oil and oil filter must still be
    changed according to the maintenance schedule.

    It takes 5 quarts. 6 if you change the filter.
  • If you don't know what has been used in it all these years, it really don't matter.I would use 10W/30 or 20W/40 myself of any brand probably Wal-Mart brand
  • A good quality oil like Pennzoil, Quaker State, Casteroil, Chevron.
    Main thing to keep it clean. Change the oil more often at first to make sure engine is clean.
    Good quality oil filter is a must.
    I run between 5000-6000 between changes less if we pull hard in the mountains.
  • Any of the quality name brand drno oils are acceptable. I am partial to Casteroil, but thats just me
