BTW, ask your mechanic to install a block heater.

In Texas that might get you a blank stare. A what? It's a small electrical element that's inserted into the coolant path of your engine block. In very cold temperatures you plug it into a standard 120VAC outlet and it warms the coolant, making for easier starting and less wear and tear on the engine.

Had to explain this to a couple of crazy Aussies I met camping last weekend. They're planning to spend the winter up here. They're sure enthusiastic about the 'adventure.' We'll see if that lasts. Though the Bundaberg rum ("Bundy!") they were pouring may help.
