Urea cost and consumption

[gbb]

I see some of the 2011 6.7 tests claim some pretty good fuel mileage. Sweet!

 

They also say the reason is no more re-gen using diesel, its urea injected.

 

All well and good, how much urea does the tank hold, what is the cost of the stuff and how much per mile will these engines consume?

 

Anyone have some numbers?

According to Fords info, it should last at least 7500 miles between fill ups - basically your oil change intervals.

 

So I know all kinds of companies offer dpf delete kits, so does/will any one make a urea bypass kit? Not that I would do so, just curious.

The motorcraft def goes for about 10 bucks a gallon. You can get def at napa for around 6 bucks a gallon. Its called "blue def" there. I think the tank holds about 5 gallons but like sportscraft said, it should last an entire oil change. The message center will let you know when its getting low. At first it warns you when there are 800 miles worth left. After it has only 300 miles of def left it starts limiting top speed to 55 mph. It will give you several more messages, start de-rating the engine until all it will do is idle. Aint the feds a bitch.
