I'm curious as to how your adventure went.
I know how to post photos I've found on the web but I don't know how to post my own.If I knew how I'd post a picture I took of the hotel lobby's big screen TV showing the current temp,the forecast and arrivals and departures at the local airport.When I arrive at about 20:30 on Thursday that screen said -42c...which I think translates out to about -44F.Yesterday morning that same screen read -40c (meaning -40F).The lowest reading I saw on my car's dash display was -38F at about 09:00 yesterday but the lowest I got a photo of was at -34F.
And...after having sat for 12 hours at -40F (or thereabouts) my car started like a champ at about 08:30.A Good strong battery and locally blended diesel came through for me once again.
And BTW...on arrival Thursday eve the first thing I did was get to a nearby Shell station (a large,modern one) and was told that their diesel pumps weren't working because it was too cold! Thankfully I found another station whose pumps *were* working.If I hadn't I would have been in big trouble.
