Greetings again, BITOG'rs!
Lubricatus Obsessus returning from a 4+ year hiatus, although lurking from outside the forum.
I can now reveal I was employed by Cummins Inc. for decades, and was let go in a massive purge in Dec. 2015. I have since retired, mostly, but of course you can't take the engineer out of the boy. I still need you guys (& gals) to keep up with the times, not being dead yet. With a shop full of machinery, friends with shops full of machinery, and now two grown boys with a bunch of machinery, I need you to advise me!
My history as a Commercial Lubrication Engineer with Mobil Oil Corporation still serves me well, but in the diesel world I've fallen behind with the reformulations for API CK-4, especially. I'll get into details in the appropriate sub-forum.
Thanks to Administrator Wayne for helping my return. I missed this site!
