A block heater is a good start during the Winter months. It's on my "to-do" list.

Don't use any power hungry and heat-robbing (cabin heater) accessories during warm-up. The engine needs all the heat it can get during the first few miles.

People tend to idle in Winter to warm up the car. Not only does it uselessly consume a fair amount of fuel, it can lead to excessive wear of key components of the drive-train on the long run and the emissions (pollution) are very high due to the rich mixture and because the catalytic converter is not yet at optimum operating temperature. The most efficient way to warm up the engine is to start driving 20-30 seconds following the initial ignition.
