Steve advises that a warm-up period of just 10 to 20 seconds is generally sufficient before driving off, especially in cold weather. He emphasizes that at this point, engine oil begins circulating effectively, and the vehicle's computer systems—responsible for monitoring air-fuel mixture and spark timing—are activated.
For drivers in neighborhoods with a few blocks before major intersections or highways, this brief warm-up is adequate. Of course, visibility remains a priority, so it's essential to ensure that the windshield is clear and the defroster is functioning to create a safe driving environment.
