Good afternoon. I’m planning on sending an oil sample off to see what I can learn from it, If anything. Who has done this, and who would you recommend using for this? Thanks.

It has been a while since I did it but I am considering it again. I will send in a virgin sample of my oil, then a sample from the engine at however many runs you like to put on it. That way you can see what is contaminating the oil without a question of if it were there before. Titanium is something that comes to mind. Was it there or are your retainers/valves putting it in the oil.

I plan to use these guys.

I use Blackstone Laboratories. They send you a test kit/s free. Put your sample in the test bottle, place in the pre-addressed envelope and my USPS carrier picks it up (scans) package at the mailbox. Blackstone gets sample and process within 2 weeks. $40 total charge to the CC. If using Blackstone fill out the included information ticket in “Pencil”.

Here’s what they e-mail back (the red print is mine not Blackstone)



I’m interested in what oil looks like 50+ runs compared to other oils I’ve used. I’m considering trying Driven GP-1 semi-synthetic 10w30 this year only because it’s listed as being Pennsylvania grade base like Penn Grade (Brad Penn).
