Oil pressure is at 65 to 70 psi at start up then drops to about 20 psi when it gets hot.

That is kind of normal for an engine they will all drop when the oil is heated up. Unless your low oil pressure light comes on or the pressure drops to under 10 psi at idle do not worry about it. The brand of oil filter can make a difference some times as well.
