what happen when you run out of DEF?

I believe it was a 2012 Volvo 670 with D12 automatic transmission. I was told it only had a 4-5 gallon DEF tank.

 

Clearly you shouldn't run out of DEF.

 

Even 10 years ago, running out of DEF had consequences

 

I think I'd rather run out of def than pump diesel into the tank 😭😭😂

 

I know of at least one other member of this forum who now feels the same way.

 

You will be drawn and quartered by CARB

 

another old wifes tale
find me an expiration date?

 

Q. What is the shelf life of DEF?
A. The shelf life of DEF is a function of ambient storage temperature. DEF will degrade over time depending on temperature and exposure to sun light. Expectations for shelf life as defined by ISO Spec 22241-3 are the minimum expectations for shelf life when stored at constant temperatures. If stored between 10 and 90 deg F, shelf life will easily be one year. If the maximum temperature does not exceed approximately 75 deg F for an extended period of time, the shelf life will be two years

I'm finally starting a new job next week, my truck will have a 6000 gallon DEF tank on it. I will be hauling bulk DEF to truck stops.
