Question lang po mga tsikoteers, mas fuel efficient ba when heating (during a cold start) an automatic tranny while in neutral, or park, or parehas lang? Pansin ko kasi parang ang lakas sa gas when heating my engine in the morning..let's say for 5 days I heat the engine for 5 minutes/day bale halos half a bar na ang nacoconsume..normal ba yun for automatics?
