I got high marks on wear rate averages. Here's a copy:BlackStone Engine Oil Analysis my 7.3L.pdf

 

Good news! Glad to hear it

I just got mine back yesterday with similar comments. I paid extra for the oil viscosity test and they want me to go to 7000 miles on my next change. I normally change oil every 4 or 5 k so I am not sure I want to try and extend the intervals. Maybe I'll try for 6k...

 

yep, I hear you man. I have an old saying you can never change your oil too often or early. Just costs more money. What cost more though is a crate motor in the long run from not properly changing oil.

 

Looks good and you could keep going on that same oil.

 

Yes sir, Thanks guys.

 

I wish mine could look like that... My truck just turned 234k miles and it looks much worse on a 5k oil change, but oh well. I get to live with knowing my engine has accelerated ware on just about everything... UNTILL.... that is, it gets replaced when I feel like spending the money! ... It's gonna have to or be damn close before that ever happens.
