I did it for awhile but your car was designed to operate at a certain temperature and it was designed to reach that temp in a certain amount of time. When metal gets hot, it expands. If your block doesn't get hot quick enough, the cylinders stay "contracted." This puts ALOT of "squeeze" on the piston and rings and can wear out cylinder walls prematurely. Something to think about. When I dropped my motor off at my machinist, that was the first thing he said to me "Good on ya."
