Interesting -
Notice how the results group themselves? Higher 600's, lower 600's, mid 400's? What happpened to the 500's?
Notice how the comments (on TDR, TDI, and other forums) group themselves by gen? Sounds like the newer the gen the higher the need for lubricity. Maybe the first gen guys have us ALL beat. The P7100 might be the BEST IP yet? Should we be finding / rebuilding 1st gen engines to be put in 3rd gen frames?
Some (most) of the products (PF etc) also have secondary purposes (pour point etc).
Lastly, what is a BAD number? and for that matter, what is a GOOD number? I know the lower the better as stated. Lets say your company runs 400 Class 8 rigs, what are the companies that watch mileage and maintenance like a hawk finding? Those guys longevity and time = serious money. What are they doing / finding?
Just some thoughts,
