The sky didn't fall yet. Put what ever in the tank you use any other time of the year

If you're storing your car you need to drain the tank. Especially if you use ethanol.

I have always just topped it off with the grade of gas I normally use (93 Octane). No difference in shelf life based on octane that I'm aware of. The less air in the gas tank the less condensation potential. Winter storage is not really long term storage.

Storage life between 87 and 93 octane is pretty much the same. The important thing in my opinion is to winter it over with ethanol-free gas if you can. "Pure" gas is hard to find these days though. I've had good luck asking around marinas, outboard motor repair shops, or small motor repair shops. If they don't have ethanol free gas on site, they should at least be able to tell you where you can get some locally.

Like above if there is a race track near by you can get ethanol free gas there too. All of the above advice is good, use a stabilizer if you want also.

You guys think to much on this. All my dad and I have been doing with are cars is nothing before winter. The car sits just like it did the last time we drove it. Come warm months we just check fluids and drive off. And the always run just like they did before there winter nap. No snake oil products no climte control atmosphere, ethonal laced gas in the tank and all.

What kind of sp gr numbers are you talking about??
From my files:
Amoco Super Premium from the 1960's had a published gravity of API 66.6 or sp gr of 0.715. RON was about 99-10. This is probably equivalent to today's (R+M)/2 of 94.
VP 110 Leaded Racing gas has a published sp gr of 0.720 to 0.735. It has a (R+M)/2 of 110
Sunoco Standard Leaded Racing gas has a published sp gr of 0.728. It also has a (R+M)/2 of 110.
So what does this difference in sp gr tell us??
