Two questions 1) which oil to use for a 2003 corolla with 23K miles,automatic.2) Should I warm the engine up before driving, esp in cold weather?Another car manual (VW Golf) instructed me to just start the car anddrive away even in the cold because (a) the car warms up faster thisway and (b) it's bad for the engine to leave the car idle warming up.
