Fuel with ethanol might have some problems over that period of time. 100% gasoline would not. Fill fuel tank before storing so the tank has little space for unwanted condensation forming internally. Put fresh oil in it, unless you are using full synthetic oil (which won't oxidize in storage).

I thought ethanol was supposed to keep it stable over time, no?
It all depends on how you are storing your car, temperature, and moisture.
If you are storing it in a garage, with low moisture, and moderate temperatures, then I wouldn't add anything.

I didn't think this would matter if the tank was not open to the elements. But I was originally thinking of just being stored in non-climate controlled garage. Either Connected or disconnected from the house.
I had a pair of Harleys for 15 years that were always stored indoors in a heated garage over the winter. I always ran 93 fuel in them and always treated them with stabil brand x before the last ride so the stabil was in the carbs.bikes were stored for 5-6 months. in about the first 10 years twice in the spring bikes would not throttle up. tore the carbs apart and they looked like molasses in the bowls. not sure why that ever happened. went to stabil brand Y and never had another issue with either bike. I am a firm believer in using stabil if you are running ethanol in your car.the cost of a couple ounces of stabil can save a lot of issues in the spring.just my .02
I guess that is one of the advantages with living in the western states.
The weather.
Deep winter I can always count on a high temp in the 50"s.
Warm enough that I could to take my Harley's for a ride with clear dry roads.
I could even run the boats in the driveway hooked up to the fake a lake.
Now with the other toys gone I can take the corvette out anytime as long as the sun is shining.
Sta-Bil contains corrosion inhibitor, anti oxidant and detergent. I use it for boat, mowers, cars, chainsaw, etc. Is it needed? It depends on conditions and gasoline quality. Cheap insurance, as I see it. I'm sure most on this forum, if not all, use premium gasoline. This is obviously good for octane needs but the composition of higher octane gasolines is also good for longer-term storage. Alkylate a key component in premium gasoline and does not contain olefinic compounds. The olefins are bad actors when it comes to long storage time.

I've rebuilt many of my friends carbs on lawn mowerrs an snowblowers that sat for about 6 months with ethanol in them. That was in Utah. If you store a motor you should use a fuel stabilizer because modern fuels are crap. Even diesels can have issues now a days. IF its my motor it gets stabil. If its a fuel tank that holds power equipement fuel it gets stabil. You may not need it in southern Cal or Arizona but you can drive your car year round, up here in the rust belt, its not a smart choice to try so our toys get stored. AND the alcohol content could be going up thanks to the gov trying to get Kavanaugh placed as a supreme court judg, as a thank you to the midwest states that helped pudh it through. Too bad
Is the orange stuff supposed to be the fuel or rust from inside the take? If rust, I find it hard to believe it will be that bad for one winter.
The orange crud is not rust. It's catalyzed ethanol. The ethanol combines with water that condenses in the tank and forms the orange crud.......affectionately referred to as "splooge" in these parts.
The fuel in this car sat for about a year throughout a restoration and repaint. No Stabil was added, my mistake!

I use a bottle of Sea Foam and a bottle of Sta-Bil. I've never had issues after winter storage with E10 93 octane. I also fill the tank as full as I can get it. I usually drain the float bowls, but have skipped that on a few occasions without issue.
Sta-bil - a poll, Is it really needed?
