Skinner Posted January 16, 2008 Report Share Posted January 16, 2008 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 Well, gasoline doesn’t really have just one freezing temperature, and in fact, gasoline isn’t made out of just one kind of molecule, but many different hydrocarbons. If you get it cold enough, it will get pretty hard. Freezing is a phase change, in which the symmetry of a system reduces -- a liquid with a random distribution of molecules turns into an orderly crystal in a true freezing phase change. Gasoline on the other hand, just has molecules that slow down as they get colder, and remain in a disordered state at lower temperatures (you might get some crystals of some hydrocarbons if you cool it slowly enough). Different components have different freezing temperatures. The alcohols might freeze first, and some of the aromatic hydrocarbons freeze at very low temperatures, below that of dry ice. The fact that they are all mixed together also depresses the temperatures of onset of solidification. An example of a common household mixture which doesn’t have much of a freezing temperature is liquid dish soap. It just gets goopier and eventually hardens up. I know this from experience, trying to wash dishes in an unheated cabin on a cold, winter morning. Glass is another example of something which doesn’t truly freeze or melt, although it becomes ductile and even liquid at high temperatures and rigid at low temperatures. Google is your friend.

Guest Removed Posted January 16, 2008 Report Share Posted January 16, 2008 basicly it gells up at around -30 (give or take) Quote Link to comment Share on other sites More sharing options...

Dave1647545494 Posted January 16, 2008 Report Share Posted January 16, 2008 its not the gasoline freezing you have to worry about if the fuel gets water in it the water freezes and can clog lines and stuff Quote Link to comment Share on other sites More sharing options...
JaSSon Posted January 17, 2008 Author Report Share Posted January 17, 2008 Speedway sold me a tank of watery gas. I'm offically boycotting the Speedway at Main and Brice. Quote Link to comment Share on other sites More sharing options...
Supplicium Posted January 17, 2008 Report Share Posted January 17, 2008 Speedway sold me a tank of watery gas. I'm offically boycotting the Speedway at Main and Brice. I use this in every tank on my DD during winter time: http://www.castlepackspower.com/Catalog/images/doubledry.gif http://www.castleproductsonline.com/anti_freeze.html Quote Link to comment Share on other sites More sharing options...
Trouble Maker Posted January 18, 2008 Report Share Posted January 18, 2008 basicly it gells up at around -30 (give or take) Funny, I've started and ran cars at -40 quite a few times. There's usually a lot more to worry about at those temps than fuel. Quote Link to comment Share on other sites More sharing options...

Like oil becoming pudding and blocks becoming brittle... But some heat shit in it and don't worry about it. Quote Link to comment Share on other sites More sharing options...
