Default Oil analysis vendor

Who is the best oil analysis company to send my oil sample to?
I tried Black stone, but they take months to send me the results. I’m looking for something quicker

I've had good luck with Blackstone ... about 10-14 days turn around on average. YMMV.

I think Blackstone is the best. I like the fact there's an actual person that break things down for ya.

Months seem like a long time. I live a little closer to them than you, but it usually only takes them 1-2 weeks. With their prelabeled kits I can track the sample via USPS and most of the time is spent in "first class" mail. Once it's deliver to them, I have analysis emailed to me in a couple days.

If you want a quicker turnaround at Blackstone, send your sample in via FedEx or UPS, with accelerated delivery. Blackstone treats them as urgent, and puts them ahead in the que.

Of course you have to pay extra for shipping if you do this.

Blackstone. Turnaround is a couple of weeks in my experience, but I can’t recall ever being in a rush to get those results.

This is who I have used with seemingly good results. I do not have experience with any other company.

I have been using these guys for many years.

Very quick turn around (week or less) and great to deal with.

My guess, especially if the slow response from Blackstone is a recent development, is that the delay is on the USPS side, on not the side of Blackstone. It would be easy to tell; just copy down the USPS tracking number and watch the journey it took, and the dates of each record.

I recently had a problem getting electronic results from Blackstone. After a few weeks, I called to ask about them. I was assurred they had been sent, but they sent them again immediately. No joy, again. After a couple of calls, the rep. sent them to me from her personal account and I received them immediately. She commented they must ‘still be having an e-mail problem’ and would pass that along. So, if you are missing results, give them a call. Great service, otherwise.

Default results

Just sent a sample to Blackstone and got results back in about 5 days by email. Seems to me that's pretty fast.
Never had one take more than a week or so.
