Starting a car while it's in hibernation for only a few minuets is not wise, there are many reasons. I'll start with the main one, your putting additional wear on the motor since there is no need to drive it. Second- starting the car and not letting it get to operqation temp is a way of adding moisture to the internals (condensation). If your worried about the battery keeping a charge then invest in a trickle charger.

But Now for things that should be done before starting.
check the oil and all fluids for moisture/ debri.
One question, How old is your gas? would you be able to dump it and put new gas in?
make sure all wires are connected.
Prime the motor as I quoted above.
start the car, do not drive it, just let it get to normal operating. Shut it down check fluids and then change the motor oil.
Better safe then sorry.
