发帖数: 2 | 1 QSome people say to not let a car warm up at all, others say wait until the
engine idle drops down, some say 30 seconds is enough, and still others say a
10-minute warmup in the driveway does no harm. What is the best philosophy?
AFrom the vehicle's point of view, it doesn't matter much. With the precise
fuel and spark control in the engine management systems of today's vehicles,
it isn't harmful to either drive them away after a cold start or let them sit
and idle for an extended period. Consid |
