is it true that your cars gas lines can freeze on a bitter cold morning, causing startup difficulties? or is this just a myth?

Sorry for the dumb question

 

I think it's true, but as long as you keep at least a half a tank in your car, then it would have to be REALLY cold before you had any problems.

 

It has to be very cold like minus 30-40 Celcius. Most cars have moisture in the tank and fuel line system that can start the freezing process. Methyl hydrate in the tank (line antifreeze) can prevent this by binding to the H20 so it won't freeze.

BPR - who used to live in Winnipeg brrrrrr

 

minus 30-40 C is how cold in F?

 

I would not leave the gas tank less than half full.

 

why would it matter how much gas is in the gas tank? If I had 1/4 tank or a half tank, how is that gonna make a difference in it freezing or not?

BTW, my HONDA isnt the one that wouldnt start this morning...it was a WRX

 

Because I've had a gas line freeze with 1/4 - 1/8 a tank, never when mostly full.

farenheight = 32 + ( 9 * Celsius/5)

 

Cold (viscus) oil and a cold battery can also cause starting problems.

 

The more gasoline... the longer it takes to freez. In the tank at least... not sure about the line it self. Just throw a flare in the gas tank to warm things up... it works for me everytime, it worked reallty well on my GSR

 

lol
Burn it to the Ground...

 

so cold you would die.

haha, what are the odds? -40C = -40F
so 72 degrees below freezing on the Farenheit scale

go internet

 

Doh! Civic tank was at 1/8 last night. Fired right up thankfully!

 

Moisture in the line freezes.

My S-03's drive like they are flat spotted when my car is left out overnight when VERY cold in chicago (like today!!). Takes a minute or two before that stops. Luckily i don't leave the car out very often at all.

 

how does moisture get in there? im pretty sure im putting gas in my car, not H2O

 

it was -41 celcius yesterday morning for me, and I only had a 1/8 tank full with the car plugged in. started up on first crank. this is on my 94 gsr, integra's are good cars.

 

Plugged in?
