My father goes overseas to work and would come back very 2-3
months. So he told me that while he's away, help him to start up
his car everyday 2 weeks or so to prevent the flat car battery. He
would fill up the cars to full tank to prevent the fuel tank from
rusting.
So what I'm saying is that I think it would be alright to leave it
and not use it for 2 weeks and just fill up the tank of your car to
prevent it from rusting.
