Blackstone labs report, compared to Speediagnostix, is not as detailed or thorough. Blackstone is less expensive though. I think by $15. My neighbor across the street has an F150 5.4 that me and my shop owner friend put an engine in about 1.5 years ago. Speediagnostix oil analysis reports for that engine is 4 pages of info. IIRC, Blackstone reports are 2 pages. I have never compared line by line though. You can visit the Speediagnostix web site to compare.
