Second Blackstone Labs Oil Analysis.

I just recieved my second oil change analysis from Blackstone labs.

History on the engine..

From the dealer, I broke the motor in hard...real hard. I did not follow any of the GM mandated "break in" procedures.

Changed first at 890 miles, then again at 3984. The oil still had high levels of copper and silicon. I have the file on pdf. format if someone knows how to post it. Yes, they are higher than "average" yet not uncommon for a newly assembled engine.

Here is an excerpt from the analysis..

TOM: High copper and silicon are both common finds in new engines such as yours. The copper is from brass or bronze parts, while silicon is from sealers and sand-casted parts. Both should settle down nicely next time, and silicon should read at or below averages next time, but copper may take a while longer. Universal averages show normal wear levels from the GM LS-3 engine after about 3,500 miles use on the oil. No fuel or anti-freeze was present and all wear other than copper looks great. We see no reason this
won't be a nice engine for you at 3,984 total miles.

Copper was 188, average 56
Silicon was 28, average was 24

So as you can see, this was the end of the second oil change. All other wear items were within normal parameters. So with that, The first oil change analysis was 18 aluminum, average 5, Copper 290 average 56, silicon 57 average 24. I would recommend an oil change before, at or around 500-1000 miles and again at 2500-3000.

So for those of you who are on the fence about oil changes...here is the proof. The analysis does not mean those high numbers would cause harm or issues, but silicon can be an issue if not changed out. Silicon content in oil is similar to running a car without an air filter on a dirt road. Copper I am not so worried about.

Yes I do...and my LS engines have over 550k with no issues or engine failures.

And I change out oil at 1000k, 3000k and after that, 8000-9000 miles on synthetic, sometimes longer depending on what Blackstone Labs reports back.
