Ford v10 engine, near end of life?

This 2002 has 190k miles. When I talked to a mechanic he said the v10 usually only goes 100k. I take off the oil cap, and it was covered in oil. The oil though was white, and had slivers of metal. I then pull out the dipstick, but that oil was light brown. What's going on? Is this the end of the road for my f250, or an expensive repair ? The odd thing is, it makes no more noise than usual squeak. I also haven't driven the truck for 10 months. But I do start it once a week
