I came back from overseas finally. Car was in care of someone who died, so after the first year, no more engine starts, and the car sat undriven for two years.

Before I left it had a full synthetic change, coolant.
Car has a full tank of gas I added an entire bottle of sta-bil to.

Trying to figure out what I should do first on a car that has sat so long.. Obviously I need to drain the old gas. No clue what I am going to do with 12+ gallons of old gas.

When I had to get rid of a bunch of stale gas myself I handled the problem by mixing a gallon or two in everyone of my cars and my neighbors cars. A small amount of mildly stale gas mixed in with good gas in a working car isn't going to hurt it.

I have found the easiest way to drain a tank on a Mustang is to disconnect the fuel filter. Put a piece of flexible line on the fuel filter. Put the flexible hose in a suitable container and force the fuel pump to run.
