Is there any chance the gasoline in the gas tank can freeze? What prevents it from freezing over?

Answer 1

The freezing point of pure gasoline depends on the difference in hydrocarbons. There are heavy and light hydrocarbons like paraffins and aromatics, respectively. Pure unleaded freezes around -97F and varies with addition of solutes such as water.

Answer 2

Gasoline will not freeze. It doesn't even thicken up like diesel fuel does in cold weather. If you experience what they call "gas line freeze" it's because there was WATER in with your gasoline. Keeping your gas tank less than half full in the winter can cause condensation to form in it which collects and ends up down in the bottom of your tank as water droplets. Then it's sucked up by the fuel pump and travels through the fuel lines. When you park your car in the cold overnight, that water will freeze and restrict or block the lines. Then you can't start your car. That's why it's always a good idea to keep your tank mostly full in the winter.

Answer 3

Well, gasoline should freeze if you get it cold enough! Gasoline does not consist of a single kind of molecule -- it contains several different hydrocarbons (molecules consisting of hydrogen and carbon atoms). In principle, if you cool a mixture like this slowly enough, it will form a collection of different types of frozen crystals, with the freezing of each type of crystal occurring over a (different) range of temperatures. In practice, often such mixtures don’t form crystals at all but just gradually thicken and harden as they get colder, forming something like glass- hard but without the regular crystal that make a true solid so different from a liquid. In a glass, on a small scale the molecules are still jumbled up like in a liquid.
In short it will freeze. But that is more of a worry with aviation fuel at -80 degrees Farenheit. Isopropyl alcohol is added to the mix to eliminate the chance of any possible trajedy in the sky.

Answer 4

Can Gasoline Freeze

Answer 5

Gasoline won't "freeze" at any temp that occurs naturally. BUT, water does get into the storage tanks and then into your gas tank. This water can freeze, causing problems for you. Just add a product called "heat" which is available at auto parts stores. This stuff "binds" to the water and makes it burn with the rest of the gas.

Spend 100 dollars and get a block heater installed. Plug in your car, as the wear on the engine at these temperatures will pay for it. The engine will start and run like summer, and warm up times are minimal, saving on gas. You may want to add some gas line anti freeze occasionally, but this shouldn't be needed if you have decent fuel available. The only other thing for cold weather, is to get your oil changed to a 5-30 blend or if you want to start in any weather, go to synthetic oil. ( 0-30)

Answer 8

moisture can get in your fuel tank from condensation in the tank, and if it gets enough of it in there it will freeze when it gets cold, some people SWEAR by heet, use it religiously, put a can or bottle of heet in every time they fill up,
if I use 2 bottles of heet a year, that's a lot and i never have a fuel related freeze up. and the only reason i put those 2 bottles in is just in case, hope this helps

Answer 9

Gas has water in it so it will freeze. If a person puts a Can of HEET in the tank this will keep it from Freezeing.If it freezes enough to the point that the gas will not flow to the engine you go nowere and the engine just cranks.

Answer 10

no,unless there is water in the tank,then,you have real problems.Best thing to do,is keep tank full over storage,if not at least half full,but you can put additives in the tank to help prevent this,condensation,causes water in gas tanks,pam
