Pretty sure their stuff is repackaged by recochem and they supply alot of the places in canada...
Dont forget your bug truck shops most of them all sell in bulk and is usually cheaper than you will pay at the pump... Def has a shelf life of 2 years and is garbage after it freezes.. All our delivery trucks are heated and our customers that we supply bulk to heat their outdoor tanks to keep from freezing
Just a word of warning if someone is pumping for you make sure they put it in the right tank.. Have seen new people fill the fuel tank with def because the caps were side by side and they did not realize what the colors meant.. Huge bill to have everything flushed
So if it freezes once its in your truck it's garbage? Considering DEF will freeze at about -11C I am thinking that most diesels in Canada would have a problem with this in the winter.
Your manufacturer will specify what is approved. According the GM "Use only DEF that is GM approved, or fluid containing the API certified or ISO 22241 label.The use of other fluids could damage the system, requiring costly repairs that will not be covered by the vehicle warranty."
Most DEF you buy in stores will be API certified or ISO 22241 labelled. I have used the Canadian Tire brand and even the Ford brand (buddy did a delete on his and had it left over). I did notice I had way less power with the Ford DEF though...lol.
