Hey DD. I went online and noticed that Pennzoil claims to sell the oil at a local chain we call "Canadian Tire" here. I drove out to one expecting to see every other Pennzoil oil BUT the diesel one. Sure enough that's exactly what happened and the parts guy also had no clue when I asked him to look through his database on the computer.
I sent a few emails to Pennzoil asking them where I can find this oil in Canada.
I'm expecting the answer to be "nowhere."
