In any event, based on what I've read it seems to me that the amounts stated in the service invoices above seem too low. A Cummins diesel FAQ says the "DEF dose rate will vary slightly amongst engine manufacturers. While most engines will have a dose rate of 2% of diesel fuel consumed, the dose rate will range from 1% to 3%." Even at a low dose rate of just ~1% I'd be expecting to use 3-4 gallons of AdBlue over the 10K service interval... or, about 1/2 tank of DEF, not 1/2 gallon.

This is going to sound random but I've been looking around online for at other diesels and what not and people are deleting the DEF system. Has anyone thought of that?

yeah, but...

In the US, there is enforcement at both the federal and state levels, which would impose massive fines on companies providing EGR/DPF Delete services or the operators who have the work done to their trucks.

Need proof of enforcement? Look no further than a $500,000 fine levied by EPA in January against Edge Products, an American company that sold more than 9,000 devices allowing owners of model year 2007 or later diesel pick-up trucks to operate without their factory-installed diesel particulate filters.
