Frankly as a retired chemist I'd be more likely to believe this if they explained what miracle additive they are using. Otherwise it sounds like marketing BS. DEF is plain and simple 35% Urea and I don't know what 'deposits they were referring to. Searching google for 'def deposits' gets zero hits.
True, and from what I've read, there is no good/better/best or "premium" DEF. It's kind of like buying isopropyl alcohol at the drugstore; all brands are the same, it either meets a standard or it doesn't. That's why I buy the Walmart house brand for $7.88 for 2.5 gallons. Peak at Walmart is $11.88. Pump DEF is even cheaper but that's very inconvenient for me.
