Thankfully, refineries can customize the product a bit for the market. They do this mostly to change the boiling point, but it affects freezing point too. Northern regions in winter will have gasoline with a lower freezing point. Southern Arizona in summer will have gasoline with a higher freezing point. Gas with ethanol will freeze lower. I would hazard a guess that for northern-state winter blend gas, going down to -70F (the freezing temperature of octane) is fine. Of course, that's probably all moot. Gasoline engines don't start when they get too cold, because the fuel doesn't vaporize properly.
