Here's what you can expect when you do a sample. Blackstone gives a good commentary based on what they see and any input you give them. The reports also show what they call "universal averages", which are the normal readings for that model engine as measured across all of them that get sampled. So in my case, the universal averages shown are for all 24 Valve 5.9L Cummins. So you get a good baseline to compare your results to.

Here is my latest report, sent in on my last oil change. Sometime before that oil change, the UNI filter in my Scotty Air II tore, so I had no idea if my engine had sucked in any unfiltered air, or for how long. Based on the results of this analysis, turns out the filter tear did not affect my engine.

 

Hopefully this helps

 

How are those breather covers working for you?

 

They are awesome! I have had a small leak in the front timing case area since I have owned the truck. Left a quarter sized puddle everywhere I parked and kept the chassis lubed up. Well since I installed these and washed the oil off, not one drop of oil has touched the ground! Should have done it a long time ago!
