Can anyone calculate insolubles from this info?
No can do. Simply not possible. Why was that data not measured? It's so important in cases like this.
This was my first UOA, so I'm not sure why it wasn't part of the test. I can say that I saw a good deal of metallic sheen when the same was first taken.
Why is it important when you have more accurate measures of Oxidation, Nitration, Soot ... etc, which many labs do not provide.
I've caused enough irritation already. I'll try to not post in this forum for at least a while but I didn't want you to think I ignored your question.

Who tested your sample? Gwood's UOA is in the same format as yours. I wish I had those numbers from you guys.
gwood and I are both Dyson customers.
RI_RS4,
If your last post was refered to me....well, I don't know what the limits are for nitration and oxidation. With Blackstone, even though they may not be as accurate, they at least give you a limit, which would be 0.6% insolubles max. That at least tells me I should do everything in my power to stay as far away from that number as I can.
I wish I knew how to read oxidation and nitration.

If you're one of Terry's customers, you can ask the question about Nitration and Oxidation.
Oxidation needs to be read in conjunction with a VOA of the oil, since some oils naturally read higher on oxidation than others.
Nitration should be as low as possible. I believe 12 is a good upper limit though.
In my simple way of thinking, oxidation and soot are indicators of the bad things in your oil. Gas engines should not have soot. If you read any, then oil is not burning cleanly, which means that deposits are forming. Oxidation is the precursor to acid and sludge formation in oil. As oxidation climbs, TAN increase follows.
Hopefully Terry will chime in, since these are his screens.

Terry provided comments on Oxidation & Nitration, but it is part of the comments & analysis that is considered intellectual property of Dyson Analysis. Maybe he will explain, but the fact that the majority don't know how to "read" the numbers seems to reinforce why he would ask us to not post the information.
I think JAG and I are on the same page and here is why:
The vast majority of reports posted here are from Blackstone, hence most people here can "read" the fairly easy warning signs (Fuel, Insolubles, Potasium, etc) from such reports. Now, I have been Terry's customer about 2-3 times and he has always read my reports from blackstones and has been able to give me a course of action.
My point is, the format seen on this report might be more accurate than Blackstone's, but a qualified tribologist such as Terry can still make recommendations based on the latter......and to a much lesser extent, so can I! Blackstone's reports are thus far the easiest to read for the average joe, hence my dissapointment in the lack of insolubles and I assume JAG's too.

A quick update...
I pulled the dipstick tonight and the oil appears to be less dark that it was about the same mileage with the Mobil 1. The color isn't really a good indicator of the condition of the oil, but whatever reaction is causing the color change seems to be sligly less with the Pennzoil Platinum. The UOA in a few thousand miles will be interesting. I'm working enough overtime right now to justify "wasting" another $50 for some oil entertainment.

5/30 or 10/30 ?

5w-30 per the warranty requirement. I'll probably continue with the 5w-30 pending the next UOA and see how it's doing. Based on a couple of other cars UOA results, I expect things to look better on this UOA.
Id go with the 5w too. Flows quicker at startup

not entirely true - look at andy's chart

Even for a young engine that Iron number looks mighty high. Our V-6 Honda was at 10 ppm by the same point in it's life.

Seems to be the trend with this motor.
