solid report. really low AL and iron and the flashpoint is really really high which is great.
i wouldn't sweat the copper one bit. on a lot of the UOA's i've seen for these trucks it doesn't truly level out into the single digits until around 35-40k miles sometimes. its on a downward trend and that's all that matters.
stayed in grade fairly well too. i'd just keep doing what you're doing, all your reports are showing great numbers.
