what do you all do for long term storing of the car for winter as far as fuel. If you put 93 octane pump in it after 4 months of storage its gonna be well lower which is an issue obviously. Do any of you store the cars with something like Sunoco 260 GT or GTX in it? I can get 260GTX locally for a reasonable price. Is it worth it to blend with pump to get say 95 or 96 octane for summer driving when IAT etc is elevated?

I fill it with 91 premium, add the recommended amount of Stabil, and never give the gas a second thought.

ive scanned mine and saw a tickle of KR on 93. thats what worries me its still cool here.

Stabil is correct, but dont get the red(most ethanol is stronger then 10%)which is for auto, get the green marine grade, I know it's made for boats, but a good (50 year mechanic and shop owner)friend told me a few years ago its 3 times stronger, and works way better. 1 ounce treats 10 gallons so 2 ounces treats 20 gal, I took a drop of it and put it on my motorcycle gas cap which had some build up, crust came right off.

Ethanol free premium and i still add Stabil

I don’t add anything to the fuel over winter. Haven’t noticed any issues in 4 years I’ve been doing it. I guess it doesn’t hurt to add some stabilizer. I might do that this winter.
