It was slightly past half full on delivery which I assume is about a bottles worth of the blue def. I bought one 0n the trip and used it. Now that I’m home after 1650 miles I’m back at just over half again. So I suppose I used a box full all together.How much DEF did you use? Was it full when you picked it up?
And it’s expensive in a gas station!! Gonna get some here at less than $10 each from Sams to make up for overpaying!
