2009 LMM regen frequency = every 357 miles

I admit I can get confused, but I'm not sure I understand the math on the urea. $50 for 6000 miles, that would be 16.6 changes in 100,000 miles. that would make $833 for 100,000 miles, not sure what it costs to do yourself I would think less. Am I missing something here? Merry Christmas to all............

Add cost of additional fuel consumed for regens. Results will vary on vehicle use. I guessed at some average consumption, well below my heavily loaded towing average...

I suspect that low cost urea sources will appear on the market, and anyone willing to buy 50gallons at a time will be doing these refills in their garage for $10 pretty soon.

We traded our 07 classic LBZ for a 2011 LML.same type 3500 CC DRW's. We get better milage towing and empty on our LML than we did with our LBZ including regens. I have only had 3 regens in 2200 miles. So the DEF is a plus in my book. Don't panic guy's, bottom line I'm getting 1.5 mpg towing and 3 mpg better empty on this new truck. And our LBZ only had the Cat and EGR. And this new truck blows our LBZ away with power while towing. And I thought our LBZ pulled great and it did. So go figure?
