High iron and copper level in oil, next course of action

Being an Aerospace Engineer and and doing regular SOAP (oil analysis) on aircraft I'm surprised that anyone would be doing this trending on a car (and a $25-$30K one at that).
It seems a little nuts IMO, we do it on a/c due to the results of a failure costs lives and they do it in F1 as a 5 position grid penalty for an engine change is better that losing all the points in a race. Doing it at a periodicity of 3-5K miles on a car??????
Drive the damned thing or trade it in if your that nervous.

It's not the cost of the oil analysis that cost is immaterial - it's the driving an owner down a road of potential repairs that are both costly and potentially not required. It's incessant navel gazing that will more than likely direct you to undertake repairs that would have been fine if left alone - this is just my opinion you guys can do what you want but I don't believe it will save you a dime in the long run!!

Interesting. Any comment on the ratio of saves for the Guardian thus far? Just curious if people send you the car after getting an alert all the time or not, for inspection at least.

Unfortunately the system has turned into a "trade in alert". Not what we had hoped for or had expected.

Hi Jake, could you please clarify if you meant all those hundreds of engines all used UOAs and all of them failed except one was saved?

You guys misunderstood me. I was saying we have carried out hundreds of UOA and one engine saw elevated levels and was caught in time and saved before failure. That doesn't mean that the other engines have failed because the majority have not and some of those hundreds were multiple samples of the same engine.
Issues progress quickly. I use UOA an particulate evaluations during development more than anything.

Wow, I would've never expected that too.

Both valid points that many of us more honorable owners also never thought of, as we think about what it takes to keep our Porsche, but in hindsight, for the average Joe, it's obvious, isn't it? Bad consecutive oil reports, or IMS alert that metal is present, but it still runs fine, just change the oil and filter, and trade it in. I mean, in the used car market, that's almost the American way, isn't it?

Just got my UOA back
61,700 miles (4.5K on Mob 1 0W40)
Copper down from 23 to 14 (since last year with 4700 miles on Mob 1)
Iron down from 13 to10
Nothing else unusual ....
Looks like i might have spotted RMS or AOS leak however while I was under there - going to watch that carefully and then decide what to do ....
