My 1990 240 DL has been sitting for months now and I need to sell it.
My question is whats the easiest way to get rid of the old gas? Can it
be drained from the tank or can I just add a bottle of HEET? Thanks.

How much is in there? If it's just a few months, I wouldn't worry about
it much. If in doubt, top it off with premium and drive it around a bit
to get it all mixed and make sure the moisture is out of it.

If you're really concerned, try siphoning it out.

You won't get all of it, though.

About 6 months. I added a bottle of HEET and topped with premium and
its fine. Car has been sitting that long with the battery in it and it
started right up. Man I am going to miss this car.

That's been my experience as well. My brother's 242T sat for over a year
and a half at my dad's place, we put a new battery in it, turned the
key, and it started up immediately, I was amazed the thing ran at all,
it appears to have had a hard life before it came into our hands.

Old gas can reach a point of deterioration where it fouls the whole
fuel system. Usually the fuel in the line will still be ok at that
point, but as I discovered with an Econoline I was given, once the bad
gas from the tank reaches the fuel injection or carb, you're screwed.
The 'smell test' is pretty effective here: if it still smells like
gasoline at the filler pipe, add some fresh gas to it and burn it off.
If it smells like turpentine or something other than gas, drain the tank.
