Greetings and good day to all in the happy computer place known as "Bitog." A statement: Recently I was reading about the Battle of Stalingrad during World War 2. As you might know, this became a winter war with temps dropping below minus 40 degrees. When Germany invaded, they firmly believed it would be a quick victory and therefore, did not prepare either men or machines to deal with bitter winter weather. Accordingly, when temps fell very low, the oil in the sumps of engines was so thick, vehicles wouldn't crank. Their quick solution was to mix oil and gasoline together to thin the oil so said vehicles and machinery would run and operate. My questions: 1. Wouldn't the gasoline evaporate once the engine reached operating temperature? 2. If so, wouldn't this gas/oil mix have to be repeated each time the engine was shut down and then restarted, (after a period of cooling of course). 3. What would this do to the lubricating qualities of the oil in the sump? In other words, wouldn't the gasoline in the oil act as a "wash" within the engine and thus "wash" the oil coating from pistons, cylinder walls, bearings, etc.? Opinions, theories, ideas?
