Ok

So, your reason to not replace every change is what, again? Cost? Convenience? Cleanliness? Effectiveness? Efficiency?

Nope. Get something OEM spec, compare prices with local vendor, and make your decision based on your needs.

Good stuff in can or bottle. Easy to apply and easy to remove. Twice a year all she needs.

NAPA

Why would you? Cost? Desire to continually conduct repair/replacement? Be afraid to take the vehicle on a road trip? I can understand “driving the wheels off” a newly purchased car that has the options you want and is what you want to be in. Own three vehicles each with well over 120k and...

I’m thinking I’d let the shop keep digging. They sound honest and competent.

Defaulting to a bad analogy - it’s like taking a good long shower then putting on your same old stinky underwear. Just don’t. Not doing it is false economy.

Blackstone Labs tested and provided baseline markers along with the actual measured. I’m not a chemE so I’m at a loss to provide additional to you. Maybe a query of the various labs would be appropriate for your interest in the test protocol.

Amalie states that it does.

Ditto.

I use Amalie Elixir 5W40 in my 15 E250 Bluetec (diesel). The oil is spec'd for MB 229.51 and I have had no problems at all. 5k oil change is my baseline and I have taken it up to almost 9k with subsequent lab analysis showing about 40% of additive package remains with no measurable metals or...

15 K is well past any manufacturer's change interval. Get out your owner's manual and study it. As far as "Fram oil", any brand that attains your manufacturer's specifications (again, read the manual), is fine. I use whatever synthetic I can find on sale that attains those specs along with a...

Last several vehicles have had well in excess of 150 k miles, one over 250 k. I change oil with whatever fully synthetic I find on sale that meets manufacturer's specifications for the vehicle. I typically stay with a 5 k change interval as the vehicles all get driven at least 15-20 K annually...

Not a good idea. Unless you wash and oil them properly it’s not an effective or efficient way to go. Just do the maintenance on time and as needed. Air filter is about every 30 k on a MB.
