Blackstone Labs Oil Analysis

Got my latest oil analysis done on the 1500 ZR2. Pulled this sample just before I went in for the recall and 0W40 bandaid oil change. It was a short change, but the trend speaks for itself. As far as I can tell, this motor is perfect. Not sure why I'd fuck it up and run 0W40, but it's sloshing around now cause GM doesn't know what the fuck they put in these motors. Anyway, should be good for 200k miles with the range DFM module.

Good news brother!👍 We are planning a trip to Lake Tahoe this weekend to camp and hit some trails....I plan on doing my next oil change on Thursday and will send mine in for analysis also. I'll post the results when I get it back. After having the Range module for over 6 months now, I am feeling pretty confident about my engine also. They said there was 900,000 plus engines that were bad but that was a worldwide number not just the United States. I think the number for the United States was around 150,000 suspected bad engines, so the numbers are in our favor👍
 
Pulled another sample on the Tahoe at 1000 miles after the previous sample showed high iron particles. I had switched to Mobil 1 0W40 FS, but haven't completed the recall yet. This oil sample shows really good numbers and no further indication of iron particles like the previous. No real explanation for the previous test, but I'll trust what I see to be good.

I guess I'll now proceed with the recall and have them save the filter so can cut it open for inspection.

Interesting to note the oil additive package definitely looks better during early use compared to a 5k change where it's mostly used up!
