Blackstone Labs Oil Report

Tip, unless you enjoy waiting weeks upon weeks. Spend an extra couple bucks and put the sample container in an actual box when you mail it. You can mail the sample container as-is with the free shipping label but in my experience the post office must quarantine the damn things or something cause they take weeks longer than just putting the thing in a priority mail box. The sample containers are somewhat sketchy looking black plastic viles that say "test samples" on them. If I worked at the post office I probably wouldn't wanna touch it either.

Yup. All there is to it. I'm sending another in as soon as I change oil, then the change after that. Don't know if it was worth it yet, but is something cool to have. Definitely would do this before buying/selling a vehicle.

Neither would I, especially if it had your return address on it.
