1st off I would say your not hijacking the thread , your just sharing info about the subject , which in my mind is what we are here for , Thanks John .
I have not seen an Amsoil report , so am not familiar with how they lay it out , I have had Blackstone , the TBN was extra and the cost was 3 times what Cummins charged .
On reports that I have seen ,they give what they call normal readings , take a closer look , maybe on the back .
Your wording is confusing / contradicting , overall severity was normal , its either severe or normal ?
Data flagged for observation only lead normal , this seems like the same , flagged / minor .
Give some of the numbers for the things in question ? I would need to look at one of my reports to tell if 10. is questionable .
TBN 8.4 is good , from what I have seen , 3 or less is starting to be bad .
If 10 is a high number , then dropping the oil pan & putting in a new set of rods & main bearings & seals , may be a good idea .
That is the other part of getting oil analysis's , so get us to do minor repair / maintainance , before components get beyond losing core value .

 

Here is my report...

 

I still do have my reports to compare to , but from memory , 2 things stick out a high iron number and high oxidation = much like mine , I forgot how many miles you had on the oil , as for the lead , my guessing is any double digit is high .
You may want to do like me and look for reasons for high oxidation .
It also looks like there is more info , lower on the page I can not see .
I went back and looked at your last post , 12,000 , again about the same , I had 14,000 .
Other wise it looks OK , just some questions , iron , lead and oxidation .

 

From my guide from Oil Analyzers Lead can come from Gas Additives, Journal Bearings, Bushings, Oil Pump Bushings, Thrush Washers and Wrist Pin Bushings.

Being have used WEO, 2 cycle oil, clean oil and other additives I would do the following. Change the oil and stop using every thing you have and see what the next 3 oil reports show. One other thing I would do is run a short oil change of say 2,500 miles with Dino oil, like Valvoline or Mobil Delvac and use the Fleetguard LF16035 oil filter to clean out the engine before you go back to Amsoil and Ea oil filters.

After the short oil run I would sample the oil at 3, 6 and 9 months or 3K, 6K or 9K what ever comes first. It could be the lead is from the used oil or additives an or the Bio and not the engine its self. But if the Lead count keeps going up after you no longer you the WEO additives etc then you have a problem. As for the TBN of 8.40 that's good with all your burning in your fuel, you don't want it to go below 2 as below that is not good for the engine and why I would change mine if it gets to 3.

BTW my Amsoil reports does not look like yours was it sent to you by Email or snail mail?

 

Neither. I had to sign into an account I made with OilAnalyzers and typed in my sample number and it brought up the report.
