My ISX's perform regular burns about every 400 miles while rolling. Many times that burn is interrupted by exiting freeways.I had to sit in a parking lot for like 30-40 mins until the tractor was done doing it's thing . and I was running an isx engine wich started to develop knocking nosies at 840 k miles. it was not a DEF truck. you would figure in todays world they would have the technology to do a regen while on the fly!! a Volvo for a local truck would def be a bad investment!!
New habits must be formed .... simply turning the truck off when it's nestled between a Prime and Swift is no longer done.
Always attempt to force a regen when stopped for your 10 or 30 minute govt required nappy nap.
Too many missed opportunities to regen will send the truck to the shop sooner than later.
