What is the freezing point of unleaded gasoline?

Question

Serious Answers only.

Answer 1

Really cold.

Based on some of the information I remember when I worked briefly as a lab tech for a petroleum test lab . . .

Fuels like gasoline are really a cocktail of hydrocarbons. Thicker, oil-like stuff at room temperature with some thinner ones, and also aromatics that are gaseous at room temperature. So by freezing, you mean, when does it turn solid? The heavier hydrocarbons will start to solidify sooner than the aromatics.

The flash point of gasoline is about -97F, meaning that it will still burn at 97 degrees below zero. Most labs won't even have the ability to chill a sample down that far to find out! Even the -97F mark is going to vary, based on the additives in the sample.

Of course, if there is any water mixed in with the fuel, it can still freeze at around 32F, but that may depend on if there are any alcohols mixed with the sample. Methyl alcohol is a common additive you can buy to help keep water in your gas tank from freezing at low temperatures.

The thicker, heavier hydrocarbons, like paraffin will become solid at atmospheric temperatures. Some of the aromatics won't turn solid until -200F to -300F. Not something you'll see outside of a lab.

For more information, the American Society for Tests and Measurements (ASTM) has written a whole bunch of methods for testing, well . . . everything really, but list some methods that may be relevant: Methods D1015, and D1016 talk about freezing points of refined hydrocarbons.

Answer 2

Freezing Point Of Petrol

Answer 3

Gasoline is a mixture of petroleum products. The various components will freeze from -97F (-71.7C) to -300F (-184C).

Answer 4

u need to worry about possible water in the gas. drygas disperses the water so it dont freeze the fuel line. gotta be dispersed in gas though.
