GAS!! epic fail
The Best V8 Stories One Small Block at Time
If you skimp on your fuel, you might as well run the cheap walmart oil as well.
The OP stated that the trans am is in storage and gets started every once in a while. This is perfectly fine, an engine just idling sees hardly any cylinder pressure, the best chance for detonation is low rpm and high cylinder pressure, neither of which will happen when a car is idling.
The owners manual even says that while 91+ octane is preferred, its still fine with 89 or 87, it specifically says that 89 and 87 are allowed the car just wont accelerate as well.
The point of my post is that the OP doesn't have to lose sleep over this, he doesn't need to hot wire his fuel pump to drain his tank, he doesn't need to put a dozen cans of octane booster in his tank, and he doesn't need to jump off a cliff or slit his dads throat. All he has to do is continue to start his car up from time to time and by the time spring rolls around all he needs to do is top it off with the highest octane he can find and let her rip
Also, a couple years ago a gas station truck driver was filling the diesel tanks at a local gas station however somehow fucked up and put diesel into the gas reseviors
That messed up LOTS of cars!!! 

. My friend have take to mechenic, drop the tank, clean injector....
