At which point does fuel freeze?

Question

At which point does automobile fuel - gasoline and diesel fuel freeze? Where I'm at the temperature's been just below zero for the past couple days - I was wondering how cold it'd have to get before the fuel started to freeze.

Answer 1

Gasoline freezes at extremely low temperatures. Fuel tends to gel slowly and eventually will freeze, but at temperatures that you would need a lab to achieve. One thing that does happen is that the water that leaks into a tank (your car's or even a gas station's) can get into your lines in a concentrated enough ratio that the water will freeze. The reason gas gels first is due to the components that make up gas. They each have their own freezing point and as they reach that point, the fuel starts to thicken. It isn't until you reach the final freezing point that the entire mass will freeze solid.

Answer 2

Fuel, gas or diesel won't freeze until it gets real cold , not sure
but its well below -50 f. closer to -100 f. But any moisture in the tank or fuel , and this is not unusual , will freeze as normal water would .if it freezes in the lines the motor will stop, out of gas so to say. to prevent this problem use gas line antifreeze for gas engines I'm not sure about diesel. Gas line antifreeze is just methal hydrate you can get it cheaper in the drug store as compared to a gas station for gas line antifreeze. One or two cups for a big tank of gas is enough , Too much won't hurt but too little will. Tripple the dose for an emissions test, it helps the engine burn cleaner. If the gas lines do freeze up the gas line antifreeze might help if it can penitrate the ice dam , but you will probably have to get the car indoors heated

Answer 3

it will not freeze ever.gasoline wont freeze.diesel fuel will gel up at your temps.if you own a diesel fueled engine i suggest going to your local auto parts store and purchasing a diesel fuel additive that will prevent the fuel from gelling up

Answer 4

properly, if the gas is gas it shouldn't freeze, regardless of the indisputable fact that throughout the time of wintry climate MTBE is added to gas till 15%/w. If the gas is diesel, properly you've massive issues. generic diesel freeze round -8°/-10°C wintry climate diesel freeze round -25°C/-30°C so that you ought to upload an fragrant compound (regularly in diesel there are close to twenty-5% of fragrant compounds which incorporates naphatalenes and alkybenzenes) case in element unrefined xylene, or toluene or ethylbenzene, all they have melting factors <-50°C and could decrease the freezing element of your gas. yet I propose you to position in a diesel heater, they artwork all proper and save your diesel from freezing or melt it before ignition.

Answer 5

the only thing that freezes is the water in gas, but gas doesn't freeze, but plug in your car and keep that oil warm so it turns over with no problems when you start it up in the morning...
