The ability to agree/disagree helps others see where we all come from on our trucks. I commend @NIsaacs and @AH64ID for being gentlemen in the differences and would love to be able to be at the table for the discussions. I long said that if you'd like to learn something, find out where the "ol' timers" hang out in the morning and pour the coffee, sit, listen and learn! There has always been a grey area in the maintenance schedules that they provide. It's almost like a hidden gotcha moment! Follow till out of warranty and then do your own thing as you wish. Just enjoy and you these trucks for why we got them!

Truck fleets track gallons consumed against engine hours

The OCI these days is 50-60k miles on a 13 or 15L .
No one sweats this angle. It won’t pay to do so. .
(Warranty specifies interval and oil brand/spec).

— Engines last X-hours and/or have burned Y-gallons.

There’s your “grey area”.

On my early HPCR it’s 350k B50, or (more importantly), 10k hours or 20k gallons.
(OCI 7.5k hard use, or 15k light use; or annually).

17.5/mpg lifetime average and 35-mph lifetime average. This is the trend to watch.

Do the figures fit your CTD spec.
