You don't got to do anything special at ALL. I never heard of stale gas in 6 months lmfao, unless of course your using sh!t gas or you have a leak in the tank to begin with.

Fill her up or not, no need for stabilizer imo. Take the battery out and keep it in a warm place thats all you need to do.

I've been doing this since the 1990s, I would even leave the car for 2 years with the same fuel and go bang 10 second passes off on the same fuel in spring , and this was over 10 years ago....

If stuff is going wrong in 6 months of sitting, there are probably other issues with the car

Maybe spray the rotors with some wd40 and throw a car cover on it, that's all If fuel stabilizer makes you sleep better, just get a gallon jug of methanol, it's the same thing and cheaper....
