DEF

I bought the DEF at the dealership and it was like $25 for two gallons.  That is really high, so looking around for an alternative, what is everyone using?  Walmart brand, Blue DEF, DEF from the Pump...?

I’ve added Blue DEF and Walmart brand. No issues. Both stores sell a lot, so it was fresh.

Make sure that what you buy is fresh.  High volume seller.  The longer it sits on the shelf, the lower the shelf life remaining, the higher chance for DEF quality concerns.
