I choose to buy my DEF from containers and prefer to stay away from bulk like at truck stops.
I'm surprised the GM trucks continue to have the contaminated DEF errors that plagued them since the launch of their DEF equipped trucks.
You have it backwards. The DEF at the pumps is going to be days old and it is stored in the ground so it is not subject to heat or sunlight, both of which shorten the life of DEF.
The commercial truck fleet operators love DEF as it keeps the motor oil cleaner (diesels produce soot and this gets into the crankcase) and allows for longer service intervals. Quite different than all the whining by people with pickup trucks.
On my last trip in June I found regular gas stations with DEF at the pumps as well as diesel. With more diesel powered cars more places provide the fuel and DEF at the pumps.
Current Ford and Ram trucks with diesel engines require the use of DEF. Don't want to have to put a gallon of DEF into the tank every 1000 miles then buy a truck with a gas engine instead.
I remember when people *****ed about catalystic converters but most people got over it and most people like having less smog - most people.
