So to update: (I’m commenting in multiple “frequent regen threads)
I added power service silver to the previous tank of fuel once I started seeing the soot load register more. After all the driving and burning down 7/8 of that tank, it doesn’t appear that the power service did anything significant to help passive regeneration or keep soot load down. I was able to make it until this morning, where my truck initiated an active regeneration based on soot, not time. 524 miles and 11 hours since the previous regeneration. Previous regeneration was 502 miles and 14 hours. So I’d call that fairly consistent so far, and nearly half of the 950 or so miles and 24 hours of the preceding 7 regen cycles. I filled my tank the night before the truck went into regeneration. This time, I tried hotshots extreme in the tank. Full bottle dose (treats 40 gallons and I have a 50 gallon tank). Drove the truck home about 15 minutes and then shut it down. The next morning (this morning) it went into regen about 1/4 of the way to work. I was able to let it run for about 14 minutes and then had to park for work. On the way home it completed. 30 minutes worth of regen total between before and after work. All highway speed at 75-77 mph. DPF gauge reading 0% upon completing. I had to make a couple trips this evening so the truck got an additional 58 miles (all at highway speed 70-77mph) and the gauge is still reading “0%”. Some things to point out:
The previous regeneration cycle was completed on the highway, uninterrupted, unloaded, and took 25 minutes to complete. Conditions were 70-75°F and very rainy with high humidity. Soot load reading of 12.5% (one bar on the gauge) returned 31 miles after Regen finished.
Today’s Regen was completed on the highway, but interrupted once. Unloaded, at 70-77mph. Conditions were 60°F for the first 14 minutes this morning and 85°F for the remaining 16 minutes this afternoon, with hot dry conditions. Soot load reading has remained at 0% currently after 58 miles of travel.
Weather conditions during regeneration definitely can impact their effectiveness, as well as alter the overall performance of the truck. Could also be a difference between the Power Service and the Hotshots in terms of performance. Time will tell as I continue through this learning process. Regardless, the one thing I can certainly say is that the overall performance of this system and the truck as a whole, seems to be very consistent. It’s just very interesting how there’s been a roughly 50% reduction in performance in warm weather. We’ll see where the data goes as time moves forward, but two regen cycles back to back at roughly 500 miles each and about the same number of hours tells me that my drive cycles are indeed consistent (as was also demonstrated over the previous 7 months)
