Thanks guys.

Something I want to add. I know in the report it explained about getting oil mid-stream which is what I did. I marked on the paper I did too so I'm not sure why they spoke about it in the summary.

Maybe because you didn't specify about longer change intervals. Also you only have about 3k on the oil. Also you did specify that you pulled the sample that way so they followed up on that. That procedure is normal unless you pulled the sample by other means like dumping it out of your oil filter. 0w20 is a synthetic as well. I doubt they had that much to say. It wasn't an extended drain interval and they didn't find anything out of the ordinary.

Both Leo’s and Steelers results have one thing Bklabs does well. Insolubles. 
In a modern ecotec 5.3 in 3000 miles 0.2 is terrible. 
Leo’s has the Amsoil bypass and full flow and has same insolubles level. Any detectable insolubles IN TODAYS engines is not acceptable.  Especially if you can filter them out or run a short interval. Suggests both aren’t tuned well or ideally.

Having said that above getting a ISO Certified oil analysis from @Black02Silverado really opens up the diagnostics and you support Nick and this site.

Oil analysts is probably good for peace of mind. And does provide good conversation. It’s been made as evidence that if you pay attention you do get warnings when your ride isn’t happy. Vehicles have been rehabilitated by flushing different oils and increasing OCIs. Turning around potential failures and restoring longevity.

I run the engine hard which is no excuse. They labeled the engine as an ecotec but it's a Gen 4 5.3l with 190k+ on the clock. I haven't had issues with the tune and my fuels trims are running within the 3% +/- mark. With a 10k OCI I don't think 0.2 insolubles is bad.

Also what's probably causing the insolubles is before I change my oil I perform a intake plenum and valve cleaning service via the dirty air pcv entrance on top of the intake plenum. 1 whole bottle of BG platinum air intake, valve and combustion chamber cleaner. Maybe that's the cause from carbon getting past the piston rings?

Maybe Leo,  but the filters set up you have you should see a lower insolubles unless its fuel related. After 45 years of oil analysis work at a OEM R&D level I am saying  that the pentane insolubles 0.2% levels is high.  Bklabs analysts don't have that level of testing experience of engines, fuels, lubes, including emission calibrations of modern engines.

Well hopefully my next sample will change. I'll skip the cleaner and try a sample then. Won't be till next year unless I magically win the lottery to afford a cam swap.

This Pennzoil 0w40 stinks BTW. At least in this application. No wonder it was so cheap!

Same thing with that oil analysis. Thats a generic industrial lab analysis. Not a good ISO Certified automotive one from @Black02Silverado. Get what ya pay for.  TESTOIL cannot compete with Nicks work by design.  12,000 miles and that wear is still terrible.
