Got New F250 PowerStroke
 

The last thing the salesperson told me after I had done bought the truck, and she had got thru with her Tutorial she told me about the mandatory EPA and DEF requirements.

I said, "What!! You didn't tell me that up front." What in the heck is DEF fluid?
She said you have to put special fluid in this port. 6 quarts of DEF. Don't let it run empty.

Well, I did not do my homework prior to buying. No one to blame but me on that.
All I knew prior to buying a Diesel engine/vehicle was that diesel cost more than regular grade gasoline.
After reading the diesel supplement book I find out it ain't 6 quarts but 6 gallons. Good Grief.
I already own a diesel Kubota tractor. But it don't need nothing special.
Well now I'm an owner of a Ford F250 power stroke so I guess I better get use to the cost to maintain it I guess.

How often does the DEF tank need filling?

welcome to db:hellox:
technicaly, they say you will need to fill it at every other fill up.
My work truck has it and i hate it.:argh:
