How nice would high octane gas be?

10% here and I've never had a problem. My winter storage procedure for the Cuda is to drive it into the garage and turn the key off. In the spring I pour a shot of gas down the carb and fire it up. I have never had a fuel related problem as a result of my winterizing procedure.
Not every car gets garage storage, some set outdoors, where they can get parked for the season & experience high 70's to sub-zero temps, heavy rains, melting snows &
the accompanying 100% humidity that goes with it. Tanks breathe, I've had cars get rarely used, drove them enough to maybe run a tank through em' if they were lucky.
Never had to worry until the last 8-10 years, now, even with the tanks full the fuel turns to s**t in no more than 1-1 1/2 yrs. & the interior of the tanks-senders-pumps are destroyed. I parked My Cutlass in the garage(unheated) and kept the tank full, started it & warmed it up once & awhile, as I gathered parts for it.....never an issue for a decade
during a move etc. . around '09 I decided to give it a good run in the early summer & a full fresh tank....and that was all she wrote.........by late next summer(unfortunately
all my cars got put on hold for personal reasons) when I fired it up it would barely run, a sample had the new dreaded cloudy look & I knew it was screwed.
The same for My turbo driver when the head cracked(previous owner got it hot once so....), sat w/a full tank (I was using this car daily & lots of miles) a year & a 1/2,
when I dropped the new engine I built in, had to drain & flush the whole tank & system....all cloudy s**t, never had that happen so bad so quickly ever in 2 1/2 decades of
playing with karts,bikes,& cars..... so whatever Dude.............................
