Looking for suggestions for oil analysis

[JamesGames]

So I have been with blackstone for quite some time now but it seems like many are saying to try something else, is there anything you guys prefer? I have a sample of 8500 mile 5w40 Xcess Gen 2 that I want to analyze but before sending out to blackstone just wanted to see what you guys think. Here are the previous results that I want to continue adding to the blackstone but willing to jump ship if you guys suggest otherwise.

Decided to stretch this interval out longer this time - looks to be decent still. But I probably will keep it at 8k-9k intervals here on out. Car sees a lot of stop and go and short cold starts from moving the car out of garage daily. It also does see a few road trips as well, so overall, mixed use.

I have also since switched to M1 0w40 FS so if I do make the switch out of blackstone, I will likely stay switched out to keep things consistent. I have taken xcessgen 2 results multiple times in a row with blackstone already.

Thanks!

If members are telling you to find another Oil Analysis Company, follow their advice, PM Pablo the Amsoil Guy here and he will set you up!

I use the Amsoil ones now which gets done through Oil Analyzers. Most of the testing from Blackstone is OK when I compared mine except fuel dilution. Blackstone estimates somehow while Oil Analyzers does by gas chromatograph.

I sent 2 samples and BS said slight fuel dilution nothing to worry about. OA said look for fuel leak at like 3.5%. I was able to smell fuel in the samples and bottom of oil filter was separating.
