Help Needed Reading Oil Analysis

I can't make much of an educated guess without knowing the amount of time/miles on the oil, the type of oil and of course the starting viscosity is important.

The wear metals are very low, but without knowing if the oil was in for 100 miles or 10,000 miles.....

I can guess by the TBN, oxidation (% or number?), nitration(% or number?) that maybe the oil has over 5,000 miles if those are %'s then for sure 7500 miles + (making the wear number very good)

If the oil started at 10W-30 it has thickened - but is it a 15W-40, or???

Funny but the additive package numbers look like Amsoil.
