When did DEF become required ?
Thinking of upgrading to a DP. I want to avoid having to deal with DEF. What year models did it become a requirement ?

DEF at the pump is about $2.80 a gallon which is cheaper than buying the 2.5 gal jug at Auto Zone for $14.99.
The DEF pump nozzle has a built in shut off that will only open when it's inserted into the neck of the DEF tank to try and prevent people from pouring DEF in the fuel tank. There is no such protection when pouring from the jug.
My semi runs about 461 miles a day and I add about 5-6 gallons every 2-3 days (when it gets to 1/2 tank, 13 gal tank) So we use about 1 gal of DEF per 275 miles. The Cat, Detroit and Cummins are about the same consumption rate.
