How did the oil look before you changed it?
How many miles on the last oil change?
How many miles on the last oil change?
Not sure how it looked before the last change and it had ~6k miles on it.
Up to 25k, OCI was 5k using whatever dealer used.
Since then, OCI was 10-14k using Amsoil SS and Amsoil filter.
Last OCI was 6k just before the most recent oil change.
Yes, it is direct inj.

Sounds like some Members here who have vehicles with Direct Injection need to chime in.
Have you ever had an Induction Cleaning on this Vehicle?
When you change the oil, you only get 90-95% of the old oil out. If the old oil hasn't been changed in a while, it's so dirty that the the 5-10% remaining in the engine will turn the new oil fairly dark. Solution is more frequent oil changes if the dark color bothers you.
Looks like the Amsoil is cleaning what was left with the dealer used oil.

What's it taste like?
It's a silly question, but no more so than looking at the color of engine oil and expecting to know anything about it's condition.
I'll give the OP a pass since he's new here.
The rest of you ought to know better.

Looks like engine oil
On contrare, the darker the oil the more fine wear particles or contaminants it contains.

Certain additives, when exposed to heat, get quite dark. Colour is a very poor metric by which to judge a lubricant.

Not true in any manner that can be objectively measured.
Oils have dyes; that's what gives them color.
Particulates alter the color, but the insolubles and soot cannot be measured via the naked eye with any credibility.
Moisture alters the color, as does fuel content, etc.
Further, even if the oil is "darker", there's ZERO indication if the oil is suitable for use or not. You cannot ascertain fuel dilution, soot loading, insoluble counts, silica, etc from a naked eye analysis of color. And, even if you could quantify the color (which you can't), how would you know which contributors were present or absent?
Wanna know if the oil is suitable for use? Get a Used Oil Analysis, not a paper towel analysis.
