I know, not very scientific, but that's all the info on our DEF usage I have right now. I will say we are getting decidedly better mileage than our previous MH (2009 Fleetwood Providence 40X) with the 8.3L engine. Also, noticeably better performance with a much heavier coach, and I'll go on to say, ride difference, WOW!

I forgot to mention that part; the Winnebago tech did mention that there would be an increase in power and that owners would notice the difference. It is nice to know that he was correct. Joe

Within a few years not any of the major diesel engine makers will be using after treatment for their engines. Navistar will overtake the market due to not needing all that extra garbage and crap on their engines. From the reports, the Maxxforce engines get better fuel mileage than the others. I have said before you really have to be a super salesman to sell what people don't want. $30,000 extra for the new urea using engines is outrageous. You can buy a new engine for less than that. Much less that much added on. The trucking industry will run as hard as they can from Cummins engines if they stay with the present technology. Money is KING! Truck Fleets can add and subtract and what they will be subtracting are engines that need urea.

Navistar Asking Regulators for SCR Recall

August 31, 2010 by RV Business

Navistar Inc. has urged U.S. and California environmental regulators to recall 2010-compliant heavy-duty truck engines using selective catalytic reduction (SRC) emissions technology that the company claims can be defeated by drivers, Transport Topics reported.

In its attack on competitors’ solutions to the 2010 EPA emissions regulations, Navistar said all 2010 SCR engines are “programmed to run without diesel emissions fluid, with the wrong fluid, with slush or frozen DEF or with the system disconnected.”

The recall request was made in a 41-page comment letter to the U.S. Environmental Protection Agency in response to the agency’s plan to conduct a “thorough review” of its SCR guidance.
