Wow that was awesome! I called the phone number, I got a PERSON not a computer, and that person was able to not only help me, but I got what I asked for via email within 30 seconds of asking. That’s customer service!

The service that you perform is a most anticipated report that I look forward to yearly. As an owner of a 30 year old classic car that I drive the %$#&^ out of, it’s always good to get your report. Kinda like a yearly check-up – am I going to live, what’s wrong, how much to fix it, how long, is it worth fixing!

Thank you for the report. Look like I am ready for a transmission rebuild. Probably will wait until we get ready to leave for the winter. You guys are a great help. Highly recommend you to my diesel truck friends.

You guys were dead on. A day before the trackday I did a boost leak test and since my methanol controller is boost actuated it triggered the pump and dumped quite a bit of methanol into the intercooler. So the car ran rich for about 5 minutes until it burnt off. Thank you guys again!

I wanted to say thank you for your prompt testing of the samples I recently sent in. I actually pulled the samples for a friend that is contemplating buying a boat and this helped him make an informed decision. You noted the difference between the two engines. Well you hit the nail on the head as this engine had been taken apart for inspection. It was determined that is was in good shape and reassembled and they decided not to open the other engine. I as well as my buddy and the seller are all impressed with your abilities. I will continue to advocate for your services. Best Regards.

I just wanted to thank you again for rushing the oil analysis on our 450 ISM Cummins engine. We brought our motorhome into a cummins shop and discovered we had a cracked cylinder head. Your analysis is what convinced the Cummins folks to dig deeper. They had told us for 2 years there was perhaps a sticky injector. We took it upon ourselves after visiting your booth at Oshkosh to get the analysis done. So kudos to you guys for helping us figure out what the manufacturers would not.

In 2009, I purchased a new Ford F-250 pickup as a company vehicle.  I change the oil regularly and periodically send a sample in. Several weeks ago, I traded that vehicle in, which had 175,000 miles on it, and took a copy of the latest results with me. The sales manager initially said they do not take vehicles with that many miles in on trade, but after driving it and reading the oil sample report, not only did he take it on trade, he gave me more than I was expecting and said he was going to call his brother, who owns a construction business, to sell it to him. He mentioned that he’s never seen anyone bring in an oil sample report and was very impressed, stating that I obviously take very good care of my vehicles.

Bottom line is that the few dollars paid for the oil analysis has more than paid off in multiple ways. First, having the oil analyzed has helped me find the “sweet spot” for the oil change interval, which I believe, has saved a substantial amount of money over the life of the vehicle. Second, the increase in the residual value of the vehicle was dramatic simply due to taking that one piece of paper with me. My new vehicle is a Ford F-150 with the twin turbo Ecoboost engine and I’ve already had to change oil for the first time. Needless to say, the sample is on its way. Thanks again for the great service and I look forward to a continuing the relationship for a very long time.

Greetings Blackstone Team, This aircraft had the induction filter blow out of position during a start up, and continued for one flight that way.  We suspect that this is where the high silicone came from. It’s a great confidence builder in your service that such a limited event can be seen in the analysis. Thanks for the continuing great reports.

The oil analysis on the AEIO-360-B2F engine in my aircraft showed high levels of aluminum, iron, and chromium. I went back and pulled the oil screen again. We did find some ferrous metal that I had at first taken to be carbon. We found enough to suspect the camshaft so I opted to pull a jug and inspect the cam. The cam was pitted and starting to spall. The high level of aluminum was coming from the piston skirts that were severely scuffed and scored. Wrist pins and rocker shafts showed pitting as well. I believe this engine was headed for a catastrophic failure in the not-too-distant future. The engine is now getting a major overhaul to be sure we got everything. Your oil analysis may have saved my ass. Thank you. You can be sure that you will be getting a sample from me at every oil change from every airplane I own as well as those of my neighbors from now on.

Dear Blackstone Staff, Thanks for the analysis. for once I don’t have any questions. At dealer prices, for every 10K I can extend the transmission service I save about 70 dollars. I think I am going for 60K next time. Thanks again.
