I still used Ceratec since they work differently. I sent my last sample in. Unfortunately I almost forgot to collect it and got the end of the stream. I indicated that on the sample. Not sure how that will play out.

For the OP, the driven oil is fantastic. It also has a fantastic price! Take a look at LM Molygen. It's a similar formulation but less costly. It's a new formula for LM, however, so I don't think there are UOA's posted for that oil (yet).

Look at tapcon's numbers in post #695 for example (picking a random recent DI40 report posted here) and compare them to yours in post #500 (what you are referring to I believe). The LM is ~2-3x higher wear metals.... Your aluminum is 4-5ppm and Iron 6-7ppm vs tapcon's 2 ppm for both.

Oil analysis looks good for 104k miles. Driven seems to show better than Motul I think. Experts feel free to chime in.

Assuming that's FR50 5w50 you're using? I like that oil and had great results with it as well.

@cannonball05 the fuel dilution went down significantly. Did you start using the Driven Injector Defender?

The fuel dilution only dropped significantly when switched to Driven. The Driven oils will inherently hold less fuel in suspension.

Or… (i) you idled less and (ii) got the engine oil hot enough to evaporate H2O and gas.

Only thing I don't like in that report is the increased Copper and not sure where that would be coming from. Everything else looks great.

There are an infinite number of factors that were not controlled for. It could be winter blend fuel contributing too, I can think of a bunch of things. But when I switched to DI40 I did the exact same test at the exact same day of the year one year later with everything as close to the same as you could be, and my fuel dilution dropped almost in half.

I am assuming that is from the bearings?

Says copper if for bushings and bearings. I wonder what would be the cause? Sounds scary...bearings. What would be a number to be concerned about?
From the legend:
"an alloy combined with tin to make bronze, which is a common material used to make bushings. Also, copper is used to make Babbitt bearings.
Typically indicates bearing, bushing or distributor gear wear. Check filter for wear debris."

I will see what the copper is in my next report. It is one point down from my last one.

Not to sound like @Mr.Moose , but copper / mile is bascially the same between all these samples. And even less concerning considering the measurement precision is 1 ppm.
