Hey, someone should start a branded DEF company.
Some german/euro sounding name. Toss an umlaut in the name. Make some performance claims, better mileage....maybe 'green too'.... Buy the peak stuff, rebox it with M///stripes....
Pay a few shills here and on other forums to talk it up, fake reviews and claims. Cut the mods in for some action and they could keep honest folks off you back.
Sounds like a plan, eh?
