Reducing cold start wear

We had glass bottle sodas in the car and as soon as we took them out of the cooler they started freezing up.

I learned that the same way, except it was beer

WW2 Russians if low on fuel in cold would turn off engines of tanks and trucks. to get going they would pour fuel on engine and light it to get warm. For aircraft they used oil heaters sometimes, but to save fuel they would never warm up, just rev and go.
