i have a block heater on my Escape but i ordered a oil pan heater for my Civic so i will see which works best.
I belive that the oil pan heater will actualy heat the whole engine but the coolant will not be at warm as with a block heater. As long as the oil pan heater warms up the engine a little i'm happy with that because the oil will be warm where with a block heater only the coolant is warmed up.
