Oil analysis sample - should I be concerned

[GJax]

Well I got my oil sample analysis back. Not sure if I should be too concerned. Here are the results. 3 items of possible concern, everything else is normal readings. If anyone has any comments please respond.

1999 Winnebago 35c, 6.8l V-10 67500 miles
Iron 40ppm
Chromium 3ppm **just above normal, indicates possible piston ring wear
Nickel 1ppm
Aluminum 9ppm
Copper 3ppm
Lead 0ppm
Tin 0ppm
Cadmium 0ppm
Silver 0ppm
Vanadium 0ppm
Silicon 34ppm ** indicates dirt, silica sand (understandable in south Texas) ingestion of dirt possible air filter debris.
Sodium 355ppm ** indicates possible oil defoaming agent, also dirt ingestion
Potassium 9ppm
Titanium 0ppm
Molybdenum 20ppm
Antimony 0ppm
Manganese 0ppm
Lithium 0ppm
No water present
Soot <.1
All other items are normal. What I understand if there is piston wear or valve wear other metals, such as iron and nickel would be present or above normal. Ring wear could be from the dirt ingestion, thus the elevated silicon and sodium levels.
The analysis indicates that flagged data ** does not indicate an immediate need for maintenance action. Abrasives (silicon/dirt) are at moderate level sodium is at moderate level, source oil additives or supplement, chromium is at moderate level possible source piston ring plating.
If anyone has input, it would be greatly appreciated. I trust your wealth in knowledge and experince

Here's a good article about what metals indicate what kind of wear. Copper and tin are bad.

It this is your first test and you don't have trend data then there isn't much that can be said on what to do next or if the high numbers are a concern.

Even though I would check your air filter, filter box and the plumen leading to the throttle body looking for possible openings that could ingest dirt. My intake system is fully intact with no leaks and my average is silicon 12 PPM. Sodium is averaging at 6 PPM using Mobile 1 and Chromium is at 1 PPM on a 2006 V10 withy 66,000 miles.
