this is after my 2nd oil change. I had changed my OEM oil at 5215 miles. at 7401 miles I added 225mL of Mr. Moly break-in fluid. I added 0.5 qt of make-up oil at 9410 (my S has never really consumed too much oil between changes). then changed oil at 10323 miles and sent it in for analysis.

from what Blackstone says, it looks like my #s are fine. I'm a little concerned that the silicon is above normal however. your thoughts?

sorry if it's hard to read, I'm having a hard time uploading a version that is small enough to display but large enough that the text doesn't get over-shrunk.

thanks in advance for any input. if any text is unclear, I'l be happy to clarify.

I think it looks fine, actually very good for 5K minoil, Chevron makes a fine oil. Honda's are known to show high silicon and copper readings - one of the tribologists at BITOG believes esters like Red Line actually "pull" resident copper into the oil more readily than regular oils, due to their polar affinity for metals. I think the silicon is likely the result of sealers, assembly lubes, and the residual sand casting material. This confirms my belief that an oil change out at 1K miles is a good idea, provided the Valvoline MaxLife Engine Protector or My. Moly break-in is added.

The metal of most interest to me is lead, which shows higher if the oil is breaking down or too thin for your engine. Yours looks fine.

The oil only thinned down to 57 SUS, which is good vis retention.
All in all, a very solid performance, proving by the way, that a quality mineral oil can do fine beyond 3K in this engine.

Where do you buy your Chevron Supreme engine oil?

thanks RR.

I swear to god, my shoulders actually relaxed after I read your posting. it's truly great to have an expert such as yourself as part of this community. nothing like a clean bill of health from our resident tribologist!

I bought my Chevron Supreme at Costco-- a big box of it. and yes, I store the bottles upside down, once again at your suggestion. ya know, I added Mr. Moly when you mentioned it in another thread. and when I change my diff oil, it'll be the LE-607 you have recommended.

thank you very much for your reply and your continuing contributions to our community, sir.

Glad to be of service.

What is this Mr.Moly that you speak of?

RazorV3

it replenishes the molybdenum(after the initial oil change) that is found in the factory breakin fluid. this is what makes the breakin oil so "special".

from the recommendation of RR in thread some time ago.

That's a pretty nice looking UOA, Tritium_Pie.

It would have been nice to see what the TBN was on this oil, just to see how much longer the oil could have held up. Since they didn't include it, I assume they didn't run it.
