Yes, you may conclude that as a cynical statement but it's just years of experience that draws me to that conclusion.

I do have all the numbers with percent power and computer claimed fuel usage, etc. All in all the UREA unit uses less fuel but it seems to be offset by the use of DEF. The way the power is placed in the engines is different though, the UREA eng would pull harder at higher percentage load hanging in longer before dropping off. My unit would pull down sooner at the higher loads but the speeds didn't seem to differ a whole lot between combines. The UREA engine gave the impression it pulled harder at higher load rates, but it didn't reflect in the speed or throughput of the machine.
As the NA combine has a smaller fuel tank (150 l ) I'm sure they will get the same running time out of both when you add the UREA into the equation.
