1_Sleek_Versa, are you serious??? You are causing extensive premature wear on the entire top end of your engine. When you start your car below freezing, the oil is thick like molasses (less so with synthetic blends) and it takes at least a few minutes for the oil to reach your cylinder head and properly coat the valves and lifters. Until this point, the metal is scraping tiny little shards off itself as it is completely unprotected and being forced to rub straight metal on metal at high speeds. These shards get flushed out with oil changes, but the damage to your cylinder head components is permanent. After a while, the dreaded top end clicking and ticking will be heard with cold starts because the components will have worn clearances between each other. The block heater keeps the engine coolant warm and in turn the oil from freezing, thus keeping the oil thin and ready to go. Not plugging in your car at -30 is almost as bad as driving it without any oil at all. If you don't believe me, mention to your mechanic that you never plug it in and see the look on his face.
