Default Old gas

i had about half a tank of gas in my car for about 3 months with no fuel stabilizer. Did the fuel go bad or am I still good?

Most likely. Cars can sit on dealer lots for much longer. Just fill it up and drive it.

If it was 6 months or more I would start to worry, but 3 months definitely isn't a problem. And even if the gas was a little bit stale, mixing it with a half tank of fresh gas would freshen things up, it's not as if you'd have to drain it out.

Fill it up and then drive it, and don't worry.

I have yet to see any modern fuel-injected engine suffer any gumming or corrosion due just to old gas, nor any failures that could rationally connected to bad gas.

Back in the old days with carbs, sure. Low pressure throttle bodies; maybe. A lot has changed since then, both in fuels and in fuel injection systems.

HTH, and have a good one,
Mike

If you want to feel better, add a bottle of injector cleaner when you fill the tank and drive off with a smile on your face and HP under your right foot!

You're fine. Many have said top it off first but I'd just burn through what you gave and reill at the 1/8th mark or so. Diluting it doesn't help much, might as well get rid of it.

I wouldn't lean on the car very hard and don't run it dry.
