DEF Additive
Has anyone done the cost comparison for the cost of DEF at the pump compared to at the store in a container? Which is cheaper?

Agree, the pump is cheaper but after experiencing the hassle of filling a jug or competing with the truckers for the pumps, etc. I choose to use the containers from Sams. A lot less hassle and it isn't a big expense anyway.
This right angle funnel is supposed to make it easier to add DEF to trucks with the Duramax. I haven’t tried it out yet as I’m currently truck shopping.
