Curious did you fill it from a jug you bought or at a dispensing station? Personally I will only use a jug that I look at and into first- DEF is too new at stations for me to trust them.
BTW the DEF tank filler port is too small to get an auto diesel or truck size fuel nozzle in it...
RalSteve- the tanks are completely separate.
