Blackstone Labs - Oil Analysis Report

[fondupot]

Recently did an oil change on my 2021 GMC Yukon dubbed "Yukon Cornelius" 5.3L. I purchased this vehicle in October of 2024 with around 63,000 miles on it. This is my 2nd time changing the oil on it during my ownership. I sent off the oil to Blackstone for an analysis, and this is the report they sent me. Very positive and very pleased. I plan to keep this vehicle for a long time and this report is very encouraging about the health of the engine. Obviously, personal data has been removed.

Fingers crossed, looks like I have one of the "good ones" with no noticeable oil usage and sold wear metal numbers.

Nice! I should do this with mine.
Curious to see how healthy she is. I know the Driven DI30 5w30 is top notch oil, but seeing some lab results is a good idea.
Thanks for sharing

Never heard of this company. I've known of Blackstone as the go-to for oil analysis. Whats different about Speediagnostix.com
