Refilling DEF Containers

Brought some DEF in two and a half gal. containers. What I am wanting to know is it OK to refill them with DEF so I have some when needed.
Thanks for all comments!

  • Yes you can refill the containers. Many of us do it. Just keep the container clean and rinse off the white crusty stuff that sometimes forms.
  • It has a shelf life of 1 year above 75 and 2 years below 72 once open if I read right. My son has a car, and it has to change every year if not driven. He get around 7000 miles per fill up. The bigger the vehicle and heavy the more it uses.

    Your RV is use a lot more. I am sure someone will ring in.
