gas freezing in lines?

gas freezing in lines? My car has been sitting since Sunday night, cold temps, hovering around freezing (it was snowing/sleeting so it couldn't have been insanely low), with about 1/4 tank left. Was gonna get gas yesterday, but nothing was cleared (no salt on roads, don't think I'd have made it far). How long does a car have to sit with temps HOW cold to have the gas freeze in the lines? I didn't worry about it until I saw the phrase tossed around in another thread and got to thinking. Thanks.

It's not really about duration but duration below a certain temp.
Freezing as in 0 degrees C or 32 degrees F is the freezing point for WATER H2O not for petrol. Petrol will not freeze until temps much much lower. Not sure of the exact temp but put it this way the rubber of your tyres will also probably have frozen, gone brittle and shattered.
Diesel is a little different and I think it can start to freeze around -5 degrees C or so.

It would also take time to freeze and need to be exposed. In an engine bay or fuel tank or under the car the temps will be higher than outside.

i read last week about gas freezing at something like -94*F but it depends how much moisture and ethanol among other ingredeints is in the gasoline as well. the coolant is most likely going to freeze befor the gasoline in the lines does.

lol @ bob barker(nice avatar). ive only seen an issue with diesel in these temps(under -2X deg celcius - the bastard just wouldnt start without being plugged in), never with fuel, and weve had temps as low as -27ish in the past few days....celcius not F, and no worries at all

Last few weeks here in northern IL have been stupid cold. We had daytime highs in the single digits (F) and nighttime lows around -11 to -7 F. For a few of those nights I had only about 1/4 tank of gas in my daily driver, and it started just fine.
You'd have to have a lot of moisture in your gas tank/lines to actually develop a freezing condition.

0*F is about -18*C.
-27*C = -16*F

its not the gas you need to worry about. it is the water in the gas from condensation or cheap gas or from being the lucky bastard to get the bottom of the tank gas when you fill up. put in a bottle of dry gas and head down the road

Best way to store your car is with some Stable and a full tank. With a full tank you have more gas, less water. ******* condesation (however you spell it) I think gas freezes at about -60F, I know at them temps a unprotected forehead will knock you out and kill you in about 5 to 10 minutes.
