diesel exhaust fluid

  1. General Discussion
    Got my first oil change "on the house" from the dealership today, but of coarse the D.E.F. is not included. They will sell it to me for $17 a gallon. I was just wondering what everyone has found to be the cheapest place to buy diesel exhaust fluid? Thanks
