    New to DEF. Never had anything new enough until now. Op manual says codes will trigger and derates will occur with even poor "quality" DEF is sensed.
    So what seems to be a trouble free brand, and for those that buy in small box containers, where do you buy? Auto parts store, Amazon, fuel depot, or do truck stops have good deals once in a while?

    Thanks.

    Those containers are too expensive. Emergency use only. I buy at pump from mostly ta or petro. No issues yet but it all looks like extortion to me.

    Anywhere, from a sealed unopened container. To much risk of contamination from bulk fill.

    After watching some youtube about quality, this is a very real concern to me. I may pay more, but I can't afford the cost of repair once contamination occurs.

    Buy yourself a locking Def cap. People have been known to screw with the trucks by contaminating Def in the truck tanks.
     
    Deezl Smoke Thanks this.

    I have a bulk tank in my garage 500 gallons
    But occasionally buy from T/A Petro at pump or fuel stop that is cheaper.
    Will tell ya though the truck stops are padding the price about $1.50 a gallon or more for sure. From what I pay in bulk
     
    86scotty Thanks this.

    "Evaporation from super concentrating"? Vapors or are you thinking condensation like in the fuel tank where water forms?
