Running a diesel engine without def is totally doable.

I own a 2007 chev. Duramax diesel, do I have one of these DEF tanks. I don't see any gauge showing this or any kind of a alarm.

Just crossed this and I'll clear up a few things........DEF will crystalize if left out or the tank goes dry. The crystals will dissolve once more (liquid) DEF is added. The DEF will freeze. It's unavoidable in cold weather. The tanks/ pumps and lines are designed for this. Once the engine is shut down you will hear a pump run, that's the DEF being pumped back to tank so it doesn't freeze in the lines or pump. The tanks are designed so they can't be filled to the top to allow the freezing DEF somewhere to expand. DEF has a shelf life, which on the upper end is around 2 years in perfect conditions, approx. 60-65F. Anything higher will reduce shelf life down to approx. 2 months at 104F ambient.
In my 6.7 Ford I wait until it tells me it wants DEF, and then add 2.5 gals. My work truck (12 Pete with PX8) I add 5 gals once the gauge hits 1/4 (10 gal tank). No need to keep the tanks full.

The FL chassis has a heater in the def tank so if you run your RV in winter for those not fortunate enough to be in Florida the def will liquefy quickly.

It can be 122 deg's here in phoenix so DEF doesn't last long but yet it does.... Odd stuff. Packaging on the 2.5 gal will say store below x degree and we never get that cool in summer! Oh well, it's what we get living in a convection oven!

Great movie.

X2 Between spring and fall when I am using my truck a lot, for trips, I top off the tank. During the winter months I do not top off the tank so all the old DEF will mostly gets used up. In winter if you do top off you want to be careful not to overfill the tank, since DEF freezes and will crack the tank if there is no room for it to expand.

Well, did you know that this line was in the original script, but was cut?
Madeline Khan : "It's twoo, it's twoo". (It's true, it's true)
Clevon Little: : "Easy baby, you're sucking on my elbow".
Boowho??

BW - no,I didn't know that. I would of loved to hear that in the movie. 
Mel Brooks is one of the greatest comedy writers in the would IMO. Even at 89 years old.

I picked up 2 1/2 gallons of DEF today just in case this happens to us! Thanks for the heads-up!

Just a heads up, a $15.00 battery pump will make life much simpler. Wait till you try and pour the DEF from the jug to the tank.

Make sure you run a couple of gallons of clean water through the pump when finished so the DEF doesn't crystallize. Just clean water, nothing else.
