Good morning my beloved nerd-powered, hard-charging, dedicated & motivated Blackstone “Lab Geeks”! Say no more fam! I’m a recently retired United States Marine Gunnery Sergeant. Did my 21 years for the Country & Corps, and fought in three ground-combat tours both in Fallujah, Iraq, and Sangin, Afghanistan! I absolutely LOVE dealing with professionals like You folks! Daggone, y’all made my day with my first report for Marta’s (my lovely wife) 2015 Acura RDX. Hot damn son! Love the details, absolutely enjoyed seeing those comments written by a real professional, and the way they are written. Folks, like I said in my first e-mail few months ago…y’all got a dog-loyal customer for life. Today I’m sending you an oil sample from my 2015 Audi Q7 TDI 3.0 V6 Turbo Diesel. I got 7,000 miles on it, and I’m starting now to keep track of it as miles pile on. I’m a lab rat myself, so I’m sending each and every one of You a huge THANK YOU and what we Marines call “BRAVO ZULU (BZ)” for doing an immensely important service to your community and our fellow ‘Mericans. Keep it up you Indiana gangsters! Semper Fidelis & God Bless! P.S. Travis, as a decorated ground-combat veteran I wholeheartedly thank YOU for being a life saver brother. If you’re ever having a bad day, remember that YOU help save lives!  One of the most, if not the most, Honorable professions in this crazy world. God bless You!  MOTIVATE!!

Having this information both saves our family money in oil and transmission changes AND saves me sleepless nights worrying about what might be happening in our engines. I recommend you to everyone I know who drives a vehicle that’s worth taking care of. Happy Spring and have a great week!

I’d like to update you all on my 01 Mustang Bullitt. The lab technician stated I had very high levels of aluminum and other metals in the engine. He even took the time to call me with his concerns and provided a more detailed analysis along with suggestions based on your oil database. At this time the engine made no noticeable noises and ran great. I ran compression checks on all cylinders and every cylinder held for 30mins+ between 200-207 psi across the cylinders. Digital scope suggested that cylinders were clean and still had cross hatches after 125k miles. This led me to disassembly for further diagnosis. After pulling timing chain cover, I found chain had deeply wore into the guide on the passenger side.

I am now a complete believer in oil reports, as I would have never known about this issue until it was too late. I have now replaced the timing chain with Ford motorsport replacement and all new gaskets. I look forward to sending my oil in for analysis later this year but wanted to update you for your database and thank you for the invaluable information that saved me a motor!

Thank you for your outstanding oil analysis. Once again, you predicted engine failure. As devastating as this past week has been, your oil analysis led me to my tuner who discovered my engine was in the beginning stages of failure. Within 3 days, my car was at a local shop getting its engine pulled, then rebuilt. It was found that when the already built motor was assembled, a mere 29k miles ago, the clearance in the rod bearings were too tight. I’m thankful that I was able to have the motor pulled and torn down before it actually failed (unlike last time). And thanks you all, it saved me lots of money. I constantly refer you all to the car community. And this is an added reason I vouch and recommend you all.

Hello Blackstone Labs! Just wanted to say thank you for the excellent service you provide. I have just received the readout on my second oil change and first diff/transmission flush on my 2013 G37 coupe. The info that you folks provide has helped me to navigate the maintenance schedule on my car, and I feel much more comfortable knowing that there is data to inform any decisions I make about maintenance and how I drive.

My father also sends his (motor) oil to you folks for his 2003 Tundra, which is where I heard about you folks. We have also recently purchased a 2015 VW GTI which will be due for its first oil change in a few thousand miles, and I will also be sending my first sample from my rebuilt 2006 ZX6R soon.

In short, my family and I love your service and will continue to send you our business for each and every vehicle we own. Thanks so much for your hard work, we value the service you provide! Aloha and big mahalo!

Thank you!!! I have been happy with everything you’ve done for us over the years but you went above and beyond on this one. I received a call from Joe (I think I remember his name correctly) telling me the paperwork hadn’t been filled out and would I be able to give him info on the engine the sample came out of. I did, but only realized much later how amazingly kind it was of him to track me down! I guess it must have been through the pre-paid testers I bought – thank you for taking the time! Next time I’ll fill out the paperwork!

Thanks to the oil analysis before this one I was able to detect 3 bad exhaust valves and a broken piston ring and had the 3 cylinders overhauled. The plane was flying great so if it wasn’t for the oil analysis I would not have known anything was wrong until it could have been a disaster. In my case I was able to get things fixed before they got much worse. Thanks!

I have been using your company for a few years and greatly appreciate your services. Your reports help me monitor my collection of military vehicles and the truck I use daily. I find your comments on the reports very informative and easy to understand. So far your company has helped me save money in my F350, by not having to change the oil every 3000 miles. Being that the motor is a 7.3L, it is not cheap to change the oil if it does not require it. Also I wanted to note that the deciding factor for me to use your company was your FAQ. I must admit that I found that to be quite hilarious and it shows that you have a great company and a great staff.

Hi, This is my first oil report ever with you guys (well, ever, ever). I’ve read sample reports posted online, but the feeling I had reading words from a human about my sample was, just, unexpectedly awesome. I dunno why, but it just was. Anyway, I just wanted to say thanks for being awesome. Also, I put no tape on my sample bottle. Thanks!

Thank you for sending that report again. I like your service and am glad I found you guys. I have severe ptsd which means I’m paranoid and my truck is my baby. I try to keep it in tip top condition and never intend to sell it. Hopefully I will pass this amazing machine onto my son as they’re (7.3L) said to reach 1,000,000 miles regularly. Please volunteer any information regarding the longevity and health of my engine. One of my favorite parts of this whole process is that it’s not just a numbers game. Someone is on the other end hand typing additional info.
