2011 Superduty is making a statement!

What kind of mileage interval / price for the DEF? I wouldn't imagine it's as bad as the BMW set up.

They say 7500 miles depending on driving habits. It's going to be very inexpensive compared to the fuel savings.

Oops. I guess I should have explained that.

What happens if the DEF runs out and you don't have any on hand? Then what?

According to the link I was watching, manufacturers will most likely force the vehicle into limp mode to enforce compliance.

DEF It should say piss here --->

well seeing as how piss has urea in it then LOL.

according to Cummins:
DEF is
32.5% automotive grade UREA
67.5% Deionized water.


That truck is BA though.

is it better than this years Motor Trend Truck of the Year?

We had training today and everything across the board is improved

So in your training today is where these improvements were made?

A year ago I was working in Ford's engine dyno lab working on the DEF systems. |Then, worked at JMT testing doing catalyst development. It is exactly that, Diluted Pig urine is what is going to be used. It doesn't increase fuel economy, it removes emissions from the exhaust. The system injects urea after the DPF and removes almost all the NOX and THC. But, then you now have to have an ASC, (ammonia slip catalyst) to remove the ammonia caused by the urea. You are correct about the vehicle going into a type of limp mode until you fill it. BUT, like every other system before it, it can be eliminated and turned off in the calibration.
On a side note, now that ALL diesel vehicles(semi's, construction machinery, and anything else with a diesel), I would expect the price of pork products to increase as it benefits the pig farms to not slaughter their pigs and have them continue to produce urine that the government is requiring vehicles to now use. I have been waiting for these systems to reach vehicle production and see what happens.
Something else I just remembered about the urea injection........the urea solution leaves a really shitty mess if you spill it. It creates a white film of crystallized residue on everything.

A few years back I worked at Chrysler in Impact Testing and we were involved with some of the early development of UREA tank/system packaging on a few vehicles. Imagine the joy a person will feel when not only do they get into an accident, but if the tank is ruptured and it spills that sh*t everywhere as well. And the tanks have to be of a decent size, so you can't just squeeze them in anywhere.

As far as I know, it only has to do with emissions, not fuel economy (as previously stated).

And the 5.4 isn't horrible, but they're really tight when they're brand new. After about 15,000 miles they get significantly better and almost feel like a completely different motor. Certainly not as good as the 6.2 is reported to be, but not horrible.

I drove the King Ranch version of this earlier this week. BIG truck for sure
