Can anyone give me an idea how many miles you get to a tank of this stuff? also how bis is the tank? This has been a deal breaker for me on the cummins ever sense the government crack down on after market delete kits.

It's really not a big deal. The tank is 5.5 gallons and is designed to last 10K-ish. If my 2013 Cummins is any indication, this estimate is accurate as long as you're running empty. Once you start towing it goes through it at a much quicker rate.

You can buy the 2.5 gallon containers at Wal-Mart for about $12, or fill up at many truck stops for $2.79 a gallon. I wasn't a fan of it at first, but it's much less of an issue than I originally thought.

Buy Terracair Diesel Exhaust Fluid | Buy DEF in bulk at Keller-Heartt

55 gallon drum $198 or $3.6 a gallon enough for your first 60k of mileage on your truck.

DEF has a shelf life, so buying in bulk for personal use is not abgood idea.

That's what I've read, and that is the tank size on the HD trucks. The cab & chassis comes with an 8 gal.

No looking to make the truck last. everyone knows the fastest way to kill a diesel is put a bunch of emissions garbage on it.

I guess thats alot longer than I figured it would. My old boss's duramax seemed to drink the stuff like crazy.

Yup after reading that. NO thanks. I guess ill find a pre def 6.7. I hope someone comes out with tuning a delete kits for the 3.0 soon.

Good thing I'm not everyone!

Why?

Genuinely curious, not very experienced with diesels at ALL...

What diesels have you owned in the past if any?

saw on autozone had 2.5 gallons for like 15 bucks but states good to 12 degrees F.

so what you do below that temp in the 1500?

They did write this:
"the freezing and unthawing of DEF will not cause degradation of the product"

They (Cummins) obviously thought about this issue and I would wager they allow the engine functions to operate normally and I have read that they add a heating element in the DEF tank for temperatures below the freezing point. I do not know if we have a heating element in the EcoD DEF tank?

Those 6.7 are awesome, too bad the 3.0 is really what works for me.

I would say... was the case with the systems placed on the 6.7 before SCR/DEF.

It was the 4th injection on the exhaust stroke to regenerate the NOx filter (and DPF) that is the culprit of the issues that plagued the earlier generation of emission controls. This created a 'wet' soot, that clogged the EGR cooler, fouled up the EGR valve, and added copious amount of diesel in our oil (at least a quart of diesel), not to mention wasted a ton of fuel in the process. Every morning the NOx regeneration occurred when I started to work and again coming home from work. (Monitored on my Insight gauge). Since the delete, my mileage went up 4mpg, and my oil changes went from 3,000 miles to 10,000 miles (even at 10K miles, the oil is still the color of dark maple syrup).

This is no longer the case with SCR, the only time when injection is made during the exhaust stroke is for regenerating the DPF, at which time the EGR valve is closed, so you dont get 'wet' soot back thru the egr cooler, egr valve and back into the intake. Moreover the DPF regeneration time is probably 300-400 miles (not sure yet on the frequency with the EcoD, however, that's what it was on my 08 not towing). Like with early emission on gasoline engines in the 70's, the diesel emission issues eventually get ironed out. In the EU, they have been using SCR much longer than we have, and believe that this system will be much less problematic than on the first generation 6.7's
