George: Your right, I never had a block heater, magnetic oil pan heater, etc. for any of my C-113 or C-123 engines and I lived in a much colder climate than you. Back in the 50s, 60s and 70s we quite regularly saw -20F to -30F, yet it never stumped those little gassers, as long as they didn't have straight 30 weight oil. They did have to be started. We used to grind grain weekly with SA or 130 belt on an old plate grinder. I remember when we saw those first British diesels here in Canada, and the first ones were not very well climatized for starting in Canadian winters. But, oh didn't the guys love them for baling hay, drilling grain, etc. I had a neighbor trade off an H and a C for two B-275 deisels, one with loader. Of course one wanted to use the loader tractor all winter, feeding, manure moving, snow moving, etc. He always claimed the best move he made was keeping his Super C. He called it his pup start for those diesels. You didn't even try the diesel if it was 0 or lower, just fire up the C-123 tow-pup start. In summary, Steve probably isn't going to see snow much more often in western Iowa than I in SW Ontario. If he puts in a more winter friendly oil, his C will start on cold mornings roughly as often as my 130, basically every time it snows. My 130 has been doing that for years with no significant engine wear. With lighter oil a well tuned 6 volt C will be good for -40. And, Steve any time it get colder than -30F in western Iowa, you should consult with the Mrs. and snuggle for the day. What you'got to do outside at -35F, ain't that important.
