question lang mga tol:
after parking your car (garage/parking lot or wherever) how soon do you turn the engine off ? may difference ba for different kinds of car (kung AT/MT or kung EFI/carburetor etc.) ?

ako kasi...practice ko lang na mga 1 minute after settling on any parking lot tsaka ko lang i-off ang engine. or if ever tumatakbo pa auxilliary fan, hintay ko muna mag-auto off bago ko patay engine.
notice ko naman sa ibang drivers, nagre-rev muna ilang beses bago i-off. any good thing about this practice?

any comments will be appreciated

thanks!
