"Extended Oil Interval" isn't your typical Thanksgiving staple, but we've got a good recipe to share regardless. No actual food-based recipes included in this one; some people got a bit touchy about that last time.

We get samples from a lot of different unit types. Trucks, boats, planes -- if it uses oil, chances are we've seen it at least once. In this episode, Blackstone Joe breaks down three reports from three different systems, detailing how we approach analysis for each one.

Some samples leave us with more questions than answers, such as: How does an air-cooled engine develop a coolant leak? Blackstone Joe invites you to send us your answers to that, and other questions raised by today's doozy of a report.

You had questions, and Blackstone Joe has answers. Topics include: can you sample even if you've added fresh oil over an oil interval? Is fuel dilution or oil consumption factored into the universal averages? What constitutes a "known problem" anyhow?

We're often asked by potential customers what good oil analysis can serve for someone who's just a regular person trying to take care of their normal old car. To that, we have an answer: early detection of a problem. In this episode, Blackstone Joe relates a case of oil analysis catching a Range Rover's coolant problem before it became an expensive nightmare.

Blackstone Labs aren't the only oil analyzers out there, and sometimes customers come to us with reports from other labs (which we will always accept and add to your file, for free)! In this episode, Joe goes through how we handle those reports, what we can do with the info, and what Blackstone offers that other labs don't.

Oil analysis is a complicated topic, and no one knows that better than a freshly hired Blackstone writer. Helping new analysts master the nuances of the various engines, industrial applications, fuels, and other samples we see on a daily basis is one of the most important responsibilities senior analysts have. Teaching new writers how to communicate that info is a whole other beast. This episode explores how we at Blackstone go about training the analysts that go on to provide you vital info with every sample.
