Here is my first Blackstone using Valvoline Premium Blue Heavy Duty Diesel 15W40. May be showing more wear than the previous 10W30 that was in it.

So I used the Valvoline Premium Blue Heavy Duty Diesel 15W40. It has higher than typical wear metals at ~7,500 interval. Then from some discussions on the org, I realized it was not FoMoCo "approved". The VPB Extreme 5W-40 Synthetic, and the "Heavy Duty" 15W-40 are, and I conflated the two together...

Just changed out the VPB (with all of 844 miles on it) for T6 Synthetic 5W-40 on the approved list. We'll see how this one does.
