About Kristin Huff

Kristin deviated from the family flock by attending Indiana University, earning an English degree. She worked as an editor and writer in Colorado and Michigan before the siren call of Blackstone brought her back to Indiana. Kristin started at Blackstone in 2002 and has since learned to love the intoxicating world of oil analysis. When she’s not working on the website, creating newsletters, doing HR stuff, or writing reports, Kristin enjoys running, swimming, gardening, and working on visiting all 50 states with her husband and kids.

As a longtime customer of your engine oil reports, I really appreciate your work. I especially appreciate your Comments section where you take a moment to review and comment on the report specifics. The light humor is the cherry on top.
Please keep up your great service and the personalized touch!

Chrissie

Chrissie came to Blackstone from a racing family. She grew up at local race tracks watching her Dad race and work with cars, so joining Blackstone was clearly written in the stars. Besides racing,  Chrissie enjoys gardening and, oddly enough, cleaning. Het two teenagers are her whole world, though working at Blackstone might give them a run for their money in terms of mom love.

Emily

Emily spends her days slinging oil in the lab, but when she’s not working, she spends her time outdoors with her kid or building (and hopefully not stepping on) something with Legos. And when she’s not doing that, she’s playing video games with friends. She has a puppy named Finley and a cat named Timmy, and is planning on growing her family with a few reptiles or possibly an arachnid or two.

Amy worked in the printing world for almost 23 years before deciding it was time for a change, landing her here at Blackstone. She is a Tampa Bay Buccaneers fan and loves to make the trip to Raymond James Stadium with her husband to watch them play.

Beck

Beck brings his data entry and receiving skills to Blackstone from a life in merchandising.

Savannah

When Savannah is off the clock, she enjoys the simple things in life – loving on her three precious cats, listening to a podcast, or spending quality time with friends and family. During the summertime, you can find her kayaking out on a lake or taking a long walk through the woods. For as long as she can remember, she’s always been passionate about traveling and attending live events. Savannah enjoys learning new things, meeting great people, and making the most of every experience life has to offer.

Normal vs. Abnormal Results

How can we tell if something’s not right? We compare to averages and compare to the trends you’ve established.

For example, we do a lot of BMW M3 samples from owners who are concerned about bearing wear. Below are side-by-side samples of a normal M3 and one with poor bearing wear.

Image of two BMW M3 samples, one with normal lead, one with abnormal lead

Both are 2003 M3’s with the S54 engine. Both have 5,000 miles on the oil, and both are running 10W/60 oil. Lead is just 8 ppm in the sample on the left, and 37 ppm in the one on the right. The engine on the right is suffering from poor bearing wear.

We have averages for most types of systems, and even if we’re seeing something new, we probably have a pretty good idea of how it should be wearing. We take into account things like shorter or longer oil changes, hard use, inactivity, contamination, make-up oil, and the zillion other factors you tell us about. Sometimes we’re stumped about whether something’s out of line…but usually we’re not.
