Where is the best place to buy DEF for my 2014 Ram? I see it in the pump at truck stops or gallon jugs at the parts stores? whats the cheapest/best route to go?
I've looked at "normal" fuel stations as well and DEF is about $9.99 a gallon. Walmart carries the Supertech brand in 2.5 gallon jugs...usually comes out to about $3.15 a gallon.
