Attached. - This is the 2nd time I have now sent in a sample of my used oil to the same lab (for continuity purposes) for anylization and a report. Just thought I'd attach it and see if there are any comments.
The 1st (baseline) report was done right at the first 1k miles. That test showed "abnormal" for high silicone content, but commented upon as to be expected from new engine (assembly materials bi-product) break-in.
This next (2nd report) is being done at 10k miles, and is the 3rd oil change since that initial report (changes being done within 3k miles apiece), the cars 4th change now, over all. The first report done 3 changes prior showed ZERO lead and nickel, where this one now shows trace amounts of each, but apparently, still within "acceptable" / normal limits. Lead and nickel early indicates wear of bearings and valves - no? :shrug:
I guess I am just paranoid about the cam-lobe & valve wear issue that seems somewhat prevalent, in our marquis. I have absolutely no evidence or indication to give me concern however, in any other way.
What do you guys think of my zinc level in the latest sampling? I know that zinc is one of those additives that for sake of catalytic converters, is being cut back on. Are my #'s high enough? Within good range? I'm just not sure what a "good" # is to have there. Anyway - again, just posted to get some hopefully good insight, and commentary, as I personally know next to NOTHING about all this stuff, and am doing it anyway, although - so far, it is all pretty much greek to me! - Any translators out there?
TIA!
Cheers,
