We got some new trucks at work and I've been driving one this week. On the dash panel there is a digital display and when it goes into regen it tells you "regen in prgress". Just like the latest flash was supposed to do for us. I noticed that it goes into regen about every 500 miles or so and lasts for about 20 minutes or so. You can also select from a menu to do a parked regen, and this also takes about 20 minutes. My question is for those of you that have an Edge w/Attitude, how often do these things go into regen, and how long does it last? Also it's strange, but these new trucks get better mileage than the previous ones. And when it goes into regen the fuel mileage according to the display only drops about .1 mpg, from about 4.6 to 4.5. Sorry about the long post, just trying to figure these things out. I don't really think the dpf is the main reason for the lower fuel economy. Thanks.
