The fuel terminals dispence straight product,i.e. no additive.Some terminals offer #1/#2 blends or even with/without additive options.Bottom line is the distributor is determining what they offer.Blending fuel or using additive costs money and the distributors try to get by with the lowest cost product they can get by with.Some distributors want to guarantee cold weather performance and some don't.It's hard to know even if you ask,the person you speak with may have no idea what's in the tank.Probably the only way to know is to ask the tanker driver as he will know what he is delivering!Cloud points(assuming no biodiesel)for #2 is maybe 5-6F,#1 is -40 or so.If you have fuel problems over let's say +10F/it's water,not gelling.By the way,kerosene is #1 nowadays.I know it's confusing.Hope this helps.
