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!
