What would be the impact if you accidentally did put a couple of gallons of water in the DEF tank? Is there a sensor/warning or is major engine damage possible?

FYI
For every 50gal of diesel, you will use 1 gal of DEF.

We average 2.5 - 3% DEF usage. I.e. 2.5 - 3 gallons for every 100 gallons of diesel.

Walmart DEF is a bother. Get a pilot RV charge card so it's fast and easy to fill up at the pump. We carry a 5 gallon blue jug that we fill every other fuel stop. We always carry the DEF can full so that while fueling, we are filling DEF. After the diesel is full, top off the DEF can. We can be in and out of the truck stop in under 15 minutes with full DEF. PLus, we don't worry about bad DEF.

Oh, and it's $2.79 per gallon at the Pilot Pump

There would not be engine damage. There could be exhaust after treatment issues. The DEF (1/3 pure urea and 2/3 de-ionized water) is injected into the selective catalytic reduction (SCR) catalytic converter. The engine electronic control module (ECM) controls the metering of the DEF into the exhaust gas stream entering the SCR. The DEF is the reacting agent that turns to ammonia which changes the nitrogen oxides (bad for the environment) into water and nitrogen. IF the correct ratio of urea and water in the DEF is changed, the aftertreatment system will activate lights, bells and whistles to let you know there is a problem. It could also put you in reduced power mode or on the shoulder of the road. It could also damage the SCR requireing replacement which would not be warrantable.

In summary: Excess water in the DEF is BAD, could cost you a lot of $$ and you would not be a happy camper.

The caution of everyone I have seen talk about it is this: DEF (both PEAK and WalMart Brand), comes with a seal like you get on bottled orange juice. If the seal is not there or is broken, then dont use it.

And, yes, the muffler (actually the Diesel Particulate Filter) has more sensors in it than you want to know, and if you had too little DEF, all your combustion percentages would be off, you would soon throw an "Engine Fault Code" on the dash (yellow idiot light), and if you ignored it long it enough, it would eventually de-rate your Cummins and limit your speed over ground. You should always check your DEF and make sure the jug is a good one before pouring it in, and that is regardless of what the name on the box is, or how much you paid.

the 2016 cornerstones have a 4% def to fuel, that means you will use 4 gals of def to 100 gals of fuel. i went to a cummins shop and had computer hooked up and 4% is new in 2010, last motorhome was 2% so thought i was using too much, wasn't for new standard

I used to use Walmart DEF but now I carry a 2 gallon jug and purchase DEF at the tuck stop. My experience is usually I'm next in line but the wait is short. You order Diesel and DEF together. Pump diesel into my tank then DEF into my jug and done. I've seen a long lines a few times but usually do me its quick.

I use a Pilot/Flying J most of the time. Yes I can save $.03 gal going to a small gas station but the PITA factor of going back and fourth to the cashier if I pump more than$100 is huge, and the quality of fuel is good.

I usually hit the pump, use my Rewards card and fill up my DEF jug first, then swipe again and pump fuel (so the pump shows only how much fuel I used for my log), while it is pumping I fill the DEF on the other side. I come back and wash the bugs off the windshield while it finishes. One stop, 15 minutes per day, and I'm on the road, good for 600+ miles.
