About a hundred years ago I was in -15F weather with a British sports car that had 20W-50 oil in it. It started.
You may feel free to divulge the make of that car, and I promise it will go no farther. But I am guessing a 1972 MG Midget with chrome bumpers and SU carburetors. Arguably one of the finest and most dependable cars ever to grace our shores. I used to drive mine in cold weather, too, but never that cold! It takes a brave man.....
