Diesel is a mix of hydrocarbons, and the components have different freezing points. For Number 2 diesel, as the ambient temperatures drop toward 32 degrees F (0 degrees C), it begins to cloud, due to the paraffin in the fuel solidifying. As the temperatures drop below 32 F, the molecules combine into solids, large enough to be stopped by the filter. This is known as the gel point, and generally occurs about 15 degrees F (-9.5 degrees C) below the cloud point.
This wax then forms a coating on the filter which results in a loss of engine power. The same thing happens on starting an engine when the temperature is below freezing. The filter becomes almost instantly coated with wax - usually, enough fuel gets through to allow the engine to idle, but not attain operating RPM. There are two common ways to overcome this: one is a diesel additive, the other is a fuel heater.
In Alaska and other colder climates, trucks are running regularly at minus 51 degrees or lower so as you see it depends on additives and heating but to freeze as in turning solid you would need laboratory conditions as nature cannot go cold enough to freeze to a low enough temperature.

What is the amount Difference between high sulfur and low sulfur diesel?
There is not a clear cutoff point between "high and Low sulfur diesel". Ultra low sulfur diesel ULSD is what is currently required for on road use. ULSD can contain no more than 15 ppm sulfur (15 micrograms sulfur per gram of fuel or 0.0015 wt.%). Low sulfur diesel would contain more sulfur than ULSD and high sulfur diesel more than low sulfur diesel.
Does sulfur dissolve in diesel?
Yes it does. ALL diesel has at least a little bit of sulfur in it; sulfur is in all crude oil. They could remove all the sulfur from diesel, but a slight amount is left in because it lubricates the engine. Low-sulfur diesel contains no more than 500 parts per million of sulfur. This fuel is legal to use in any engine made on or before December 31, 2006. Ultra-low-sulfur diesel contains no more than 15 parts per million of sulfur. This fuel is required for all engines made after January 1, 2007, and you can use it in any diesel engine.
What is the impact of ultra low sulfur fuel on emissions?
Ultra-low Sulfur Diesel (ULSD) Zero Net CO2 Emissions ULSD does not reduce carbon dioxide emissions.• ULSD allows manufacturers to apply to diesel vehicles technologies to control the emission of nitrogen oxides (NOx) and particulate matter (PM) that the presence of too much sulfur would not otherwise permit. Together, ULSD and the technologies are called Clean Diesel.
What is the red color in fuel oil?
It's just a dye to differentiate it from other grades of fuel. Some diesel fuel has a red dye to indicate that it is ultra-low sulfur grade.
How many BTU per gallon of Ultra low sulfur diesel?
Around 138,370 Btu per gallon, according to ATRI: ULSD Has More Energy Than Engineers First Expected] (1/26/2009). This is 7.227 Gal/MMBtu. Thare are other numbers commonly in use, 139,200 and 140,000.

What is the difference between red diesel and normal diesel?
sulfur content regular ultra low sulfur diesel is 15ppm. off road, no tax, red diesel what ever you want to call it has 3000ppm
Is airport diesel fuel ultra low sulfur?
Not yet, nor is it important.
Can you use 500ppm diesel in a common rail engine?
Pre 2007 diesel engines can run on 500 ppm diesel fuel. 2007 and later diesel engines that call for ultra low sulfur diesel fuel should not. These systems use EGR and the extra sulfur in the diesel creates sulfuric acid by nature and will then be reintroduced into the combustion process. Even later diesel engines are using diesel particulate filters that are sensitive to the extra sulfur. Bottom line, if your engine says that it is rated for ultra low sulfur diesel fuel (15ppm) use it.
Do Pemex stations in the Baja have ulta low sulfur diesel?
Pemex stations in the Baja Sur have ultra low sulfur diesel, also known as ULSD. Pemex stations also offer low sulfur diesel, also known as LSD.
Can you use high sulfur in 2008 Ford truck?
you can but it will cause damage to the Diesel Particulate Filter (DPF) and other emission componets. It would take about $8,000.00 to replace parts. As far as I know all diesel that is sold now is ULSD.per for shop manuelNOTICE: For areas where ultra low sulfur diesel fuel (15 ppm sulfur maximum) is required, use only ultra low sulfur diesel fuel in diesel vehicles equipped with an Oxidation Catalytic Converter (OC) and Diesel Particulate Filter (DPF). In a diesel vehicle that is continually misfueled by using low sulfur (16-500 ppm) or high sulfur (500 ppm or greater) diesel fuel, the sulfur can effectively poison the catalyst. Continuous use of low sulfur or high sulfur can destroy the catalyst and render the catalyst useless.
Can you buy ultra low sulferdiesel fuel in Mexico?
No. Mexican gas and diesel have a large concentration of sulfur.
Does red diesel damage your engine?
It will not damage your engine but it is illegal to on the road. The fuel is dyed for use off road. Off road Diesel is not taxed like on-road diesel. Also, the newest on-road diesels require ultra low sulfur fuel, and red is not always low sulfur. It will wipe out your particulate filter, which is expensive (and won't be warrantied). Often red diesel is straight #2. So it needs additive if it's much below freezing.
What can we do about preventing acid rain?
Avoid putting sulfur into the air. This can be done by burning low sulfur coal, or by using scrubbers to remove the sulfur from the exhaust. Also use ultra low sulfur diesel fuel.
What is the effect of using High sulphur Diesel fuel?
They don't sell that anymore. There is Low Sulfur Diesel (less than 500ppm Sulfur) and Ultra Low Sulfur Diesel (less than 15ppm Sulfur). If your vehicle says "ultra low sulfur diesel required" you have a diesel particulate filter. (You might also have a Selective Catalytic Reduction reactor or an Advanced EGR system if you have a 2010-on truck, but if so you also have a DPF.) You can run LSD in your engine occasionally--like if you need some fuel because you're about out of gas and there's nothing else around--but running LSD all the time in a newer truck will ruin the diesel particulate filter and they are not cheap.

Can you use Mexican diesel in your 2008 super duty diesel truck?
Diesel sold outside of the United States may not meet the US standard for ultra-low sulfur diesel. Ultra low sulfur diesel contains 15 PPM of sulfur, whereas diesel sold in countries such as Mexico will most likely have upwards of 500 PPM (parts per million) of sulfur. Using this diesel in a 2008 Super Duty will quickly cause very severe and costly damage to the emissions components of the vehicle. The diesel particulate filter in particular will likely be clogged very quickly due to the excessive amounts of soot generated when using fuel containing high amounts of sulfur. The symptoms of using fuel containing high amounts of sulfur will also be immediately noticeable if the truck were to be taken in for repair, likely voiding the warranty on the vehicle.
