How long is treated fuel good for?

[thumpar]

I filled my tank with mid-grade and treated my fuel at the end of last season (mid-september) with fuel stabilizer. We just had a baby and we don't plan on getting out much this summer. I hope that I will use up what is in the tank now. It is a small tank in a 1983 16.5' Sunrunner with merc 120. I would guess the tank to be around 25 gallons. So is this gas going to be OK over summer and maybe a bit of it left mixed with the new fuel and stabilizer until next year or should I drain it at some point? How long does it last stabilized?

Drain before winterizing. last at most 1 year.

Run it. Don't waste it. If you stabilized it it will be fine. If you use a little up this season, top it off and restabilize it. Boat motors are relatively low compression and will work fine with stabilized 2 y/o gas. Now if your gas has AG's politically mandated blend then all bets are off.

LOL. I figured if there is still some in the boat I will sell it. I paid low $3 for it. just kidding. Just to be sure I will use it all in the boat and maybe some in the tow rig.
