It had gotten to -10F on Tuesday night. The 1100 is parked under a carport, on concrete, that acts like a wind tunnel. It never got above 22F yesterday.
Yeah, we normally don't get cold weather in Tennessee. Most winters, we might get a one or two inch wet snow fall overnight, but by the next afternoon, it is 55 F out and all of the snow has melted.
This snowstorm/Arctic weather snap kind of hit us by surprise. Sunday was clear and in the 30's. Monday, we were only supposed to get maybe an inch of snow and the temps in the teens for a high. GOt up to go to work Monday morning and we already had 4" on the ground and it was coming down hard. We ended up with 9" of dry snow and that is when the temp started plummeting. Tuesday night, temps went to -10F. Never even gave a second thought about treating the diesel fuel, because it ran so well all day Monday in the snow storm. I put some Diesel Service 911 in it tonight, did the usual shake, glowplug, crank routine and finally got it started after about 10 minutes.
