I've been using Opti-Lube Summer diesel additive in my 6.7L since my first fill up, and started combining it with AR6200 fuel additive at about 2000 miles with good results. At my first oil change at 5000 miles with 5W40, I added AR9100 to the oil.
When the cold finally got to Vermont this week, I started using the block heater and Opti-Lube Winter with morning temps between plus 5 and minus 10. I didn't bother last night thinking it would be warmer, but it was 5 degrees when I went to the truck this morning. I turned the key to on, waited for the glow plug light to cycle off and cranked it. It a second, it was idling smoothly at 1200 RPM. This stuff is working!
I started recording regens 1000 miles ago and went 600 miles between the last two and have 400 miles since the last one with soot gpl at 1.55. All three products claim soot reduction and I believe it.
I have a 76 mile daily round trip commute with speeds from 25 to 70 and do see some passive regen.
