Blended gasoline and Anti Icing Fluids

We now live in a condo with heated parking. The winters are very cold, for example it is about 10F this AM. My concern is the increased exposure to fuel tank condensation and resulting water in gasoline. Do the alcohol blended fuels still require anti icing fluids?

  • x2 on fuel stabilizer and a full tank. Although not fuel related, disconnecting the battery if there's no trickle charger or similar maintainer is a good idea too. None of this is all that necessary if the vehicle is used on a relatively regular schedule.
  • I'd toss in a fuel preservative like Sta-Bil or Star-Tron just to keep the gas good, and make sure the tank is full. If this is done, I've not read about issues with starting come spring.
  • Agree. If you've already got 10% alcohol, adding 10 ounces more is meaningless.
  • The short answer is NO.
    If the fuel does contain alcohol, that is all that fuel anti-ice ever was.

    If you should accumulate so much water in the fuel that the alcohol water precipitates out, that mix is still pretty freeze proof. The caveat here is that I have never done cold start work in Edmonton.
