Really? I haven't noticed more frequent regens in the heat and it's always humid in Tulsa. I feel it should be just the opposite, higher temps outside = higher EGT's so more passive regens.

Probably not as near humid where I'm at along the Gulf coast. You would think the higher temps would help like you say, but even the miles to complete a regen on my truck is ~10 miles whether it's cold or hot.

Wow... That's way shorter than mine, and I'm usually climbing hills at 65 mph during an active regen. Wish mine did them that quick. But mine have seemed to shorten up using the FBC.

I have ‘15 I’ve owned since new, currently at around 165,000 mi. I was going to start a thread on this very subject, my regens are down to roughly 300 mi. From previous years of almost every one going out to 500 mi.
I’m not buying the heat and humidity argument. My regen duration seems to be the same, roughly 24 mi., and for the most part they go down to 20%.

My truck regens between 200 miles and +250 miles depending on ambient temperatures, so it makes sense that my truck regens in about half the miles.

my unicorn would regen at a max of 10 miles (2013 drw F350). Would not regen when towing (passive regen only).
Regens (active) were only during unloaded miles.
My 2021 regens like clock work since new at 496 miles....always, towing or not.
I beleive higher HP and less EGR and more use of DEF and current factory tuning is different. As for the length of the regen, around the same 10 miles to get er done.

I was curious if weather/humidity would make a difference on regen but IMO 90+ and humid on a few 600 mile drives and only 1 regen. Fortunately on the highway and not pulling into my neighborhood lol.

My regens are always shorter when they happen in town as opposed to on the highway. My guess is that the increased air flow across the exhaust on the highway keeps the exhaust temp down. Higher temp = quicker regen.
