Urea injection is a misnomer. Urea is a solid and cannot be injected. The trucks that use urea injection use an aqueous solution of urea, usually 32.5% urea the rest water. DEF (Diesel Exhaust Fluid or Diesel Emissions Fluid) is also a solution of urea and water, usually 32.5% urea known as AUS32. As far as I can tell "DEF injection" is just the new more correct term for "urea injection".
OK since they are making a built in tank in 2010 for the new solution ( which will probably be very expensive from dodge) I wonder if you will be able to substitute water-meth in this !!
