Inside switch is best or if one has a consistent schedule those little indoor/outdoor timers are cheap and effective.

Metro did a block heater test. I use as a rule of thumb that one hour on won't achieve maximum temperature gain but it is almost there and quite enough to be helpful; more than two hours on doesn't achieve much of anything but heating the great outdoors and running up the electricity bill.
