In freezing weather, an emergency treatment replenishes frozen or gelled fuel, getting your vehicle back on the road and saving you time, money, and hassle!
In cold temperatures, use to liquefy frozen or gelled diesel gasoline caused by wax production or ice crystals. Quick-Thaw will completely thaw the whole fuel system in roughly 20 minutes if applied according to the guidelines. Excellent for diesel cars operating in colder locations, where wax crystals found in low- and ultra-low sulfur diesel fuels can cause filter blockage.
A bottle of Quick-Thaw should be kept on hand in every diesel truck for emergency cold weather rescue treatment.
How long does it take to thaw fuel lines?
Bringing the car into a warm environment, such as a garage, and allowing the entire car warm up for an hour or two is one of the most effective ways to treat a frozen gas line in car terms. If you don’t have access to a garage or a warm place to park the car, cover the engine with a blanket and hang a drop light on the hood for a time. The light’s heat should assist in warming up the engine and fuel lines. Even a small amount of thawing of the lines will aid in the movement of gasoline through the system.
Keep the automobile running for a bit once you’ve gotten it started. If you’re having problems with sputtering, try revving the engine a few times. It’s recommended to avoid driving if the engine is sputtering, as this could signal the start of a sudden stall.
If all else fails or you’re short on time, try using fuel additives designed to melt frozen fuel lines. Most automotive stores sell these additives, which will melt frozen gasoline lines in around 20 minutes to a half hour.
Keep your gas tank as full as possible at all times to avoid your fuel lines freezing in the future. Excess air in the tank and pipes makes it easy for them to freeze, so maintain the tank full to keep as much air out as possible.
Make sure your battery is fully charged at all times. Your battery will not have enough power to work the gas through partially frozen lines if it is nearly dead. The more power you have to pump the fuel through the system, the greater your chances of starting and keeping the automobile going.
Will diesel fuel Ungel on its own?
A variety of things can be put to a gelled tank to aid in the recovery of the fuel to its original state. Opti-Lube Gel Melt and Diesel 911, for example, are made specifically for gelled fuel. Simply fill the tank with one of these and follow the dosing directions. There’s no need to heat or mix the tank. These can take a long time to install, depending on the size and shape of the tank. The treated fuel in the tank may not be able to reach gelled fuel that is not in the tank, such as in fuel lines and filters, which is a significant constraint.
How do you fix frozen diesel?
If the cold weather catches you off guard, your diesel-powered rig or light vehicle may be difficult to start or not start at all.
This happens because diesel fuel thickens inside filters and fuel lines, clogging your truck’s fuel system by forming a gel. For a truck owner/operator or anyone trying to travel and gets trapped on a dark and lonely highway in the middle of nowhere, this may be a very costly cost. Depending on the severity and location, emergency call outs to defrost a gelled system can cost anywhere from a few hundred dollars to a few thousand dollars.

At what temp does diesel freeze?
What is the temperature at which diesel fuel gels? That’s a tough question to answer because your diesel-powered vehicle won’t drive anywhere in the cold if you don’t prepare properly. Fortunately, the problem can be readily avoided by applying a gasoline additive, which can help stop gelling from happening in the first place. While it’s important to prepare your vehicle before the cold weather arrives, acting quickly can help you avoid a breakdown.
At What Temperature Does Diesel Fuel Gel?
When the temperature drops below 32 degrees Fahrenheit, the paraffin in diesel fuel begins to harden, clouding the fuel tank. This modification will not prevent you from driving, but it will serve as a reminder of how colder weather affects gasoline use.
Gelling happens when the temperature falls between 10 and 15 degrees Fahrenheit, blocking the gasoline tank and fuel lines. You may need to have your vehicle towed to a garage at this stage so that your mechanic may repair any damaged fuel lines and thaw the fuel tank.
How Do You Prevent Diesel Fuel From Gelling?
If you utilize a fuel additive, you can drive a diesel car in subzero temperatures. A fuel additive designed for diesel engines decreases the fuel pour point (the temperature at which it freezes) by as much as 40 degrees. It also inhibits gelling by dispersing water.
The crystals that form in diesel fuel during cold weather are altered by a diesel fuel additive. The additive lowers the size of the crystals in diesel fuel, preventing it from waxing or gelling. It alters the fuel’s chemical characteristics, allowing it to flow at temperatures considerably below zero degrees.
If the diesel has already gelled, an additive can help. To begin, empty the tank and disconnect the fuel line. Typically, this entails pouring the additive into the tank and waiting 20 minutes for it to break down the gel before starting the vehicle, but check any directions carefully to ensure you’re following the appropriate steps. Allowing your vehicle to idle for a few minutes will allow the fuel lines to clean.
Cold Weather Preparation
There are a few more things you can do to prepare your vehicle for cold weather besides utilizing a diesel fuel additive. First, make sure your battery is in good working order. When the weather turns cold after a hot summer, the battery is more vulnerable to failure. Replace your battery if the reading is less than 12.45 volts on a multimeter. You don’t want to have to deal with battery troubles on top of fuel issues.
Second, if temperatures are really low, an addition may not be sufficient. Keep in mind that an additive can reduce the pour point by up to 40 degrees. It can prevent blockage in temperatures as low as minus 30 degrees Fahrenheit. We all know that colder temperatures are feasible, and that the addition may become useless as a result. Even if the temperature does not drop that low, a block heater may be required, especially if you park outside. Make it a habit to turn on the block heater when the temperature drops below freezing.
You may avoid being stranded on even the coldest days if you take excellent care of your diesel vehicle and its gasoline.

How do you start a frozen diesel engine?
“Rise and shine, campers, and don’t forget your booties because it’s chilly out there today…. Every day is chilly out there. What the hell is going on at Miami Beach?” (From “Groundhog Day”)
That’s true, here in the Rocky Mountains of Colorado, winter has returned. With a so-called “polar vortex” expected tomorrow, we thought it would be appropriate to display a video of some of the best “cold diesel starts” from last month, as well as provide some recommendations on how to start a diesel engine on a chilly day. Take a look at some of the suggestions provided below.
A Few Tips On Starting a Diesel Engine On a Cold Morning:
1. Glow Plugs and Block Warmers: On a chilly day, the vast majority of diesel engines can be started with glow plugs or block heaters. Glow plugs work by heating the internal combustion chamber, allowing for proper compression and, eventually, ignition.
2. Wait for the Glow Plugs to Warm Up: If the combustion chamber isn’t sufficiently heated with glow plugs, cold fuel sprayed over the semi-heated plugs will cause the diesel fuel to gel and stick to the cylinder heads. The wall of the heads or the surface may be damaged as a result of this.
3. Install a Second Battery: Make sure you have a fully charged battery or a separate battery specifically for the glow plugs installed. Glow plugs require a significant amount of power from your vehicle’s battery to operate. The capacity of a battery to keep a charge decreases as the temperature drops. At 75-80 degrees Fahrenheit, a battery will have 100 percent power available, but at 0 degrees Fahrenheit, it will only have 46 percent. Installing a second battery could mean the difference between the motor starting and not starting.
4. Change the Oil Frequently: At 0 degrees F, an engine is typically 2-3 times harder to start due to heavier oil lubricating the engine’s hard internal parts. The greater resistance on the bearings and moving parts, the thicker the oil. Most people are unaware that the crankshaft does not “sit” on the bearings; rather, oil pressure raises the crankshaft, which floats on top of the bearings in an oil cavern. Having enough new oil with a high chemical grade will assist in keeping the internal diesel engine parts lubricated and aligned.
For diesel engines, both synthetic and natural mineral oils are suitable. Oil “goes bad” mostly as a result of chemical bi-products from the combustion cycle, such as silicon oxide and different acids, being captured in the suspension. It also loses viscosity by transferring a lot of heat away from the combustion cycle and limiting oxidation exposure at higher temperatures. Diesel engine oil is destabilized by heat, pressure, and chemical reactions.
When oil fully oxidizes, the additives separate and begin to chemically break down, resulting in black engine sludge. If a diesel engine is not unclogged and cleaned, sludge will eventually ruin it. As a result, it is critical to change the oil on a frequent basis, especially in colder locations.
5. Turn Off All Non-Essential Accessories: On a chilly winter day, you only have so much battery life available. When starting the engine, turn off headlights, radios, iPods, phone chargers, heaters, and air conditioners. If at all possible, avoid using these gadgets while the engine is running. These devices divert vital amps away from glow plugs.
6. Use the Correct Diesel Fuel: There are two types of diesel fuel: Diesel #1D and Diesel #2D. The most extensively utilized diesel fuel on the market is Diesel #2. If you go to any gas station, you’ll almost certainly find Diesel #2D as the major fuel option. Diesel #2 is the standard fuel recommendation for regular driving conditions, according to all of the major auto manufacturers. Diesel #2 has a lower flammability than Diesel #1. A higher cetane number indicates that the fuel mixture is more volatile. For light-duty diesel engines, most manufacturers recommend a cetane rating of 40-45. Due to the higher fuel economy, heavy haul truck drivers prefer to utilize Diesel #2 over long trips. More combustion stability = greater, more consistent fuel mileage.
In cold weather climates, however, Diesel #1D is advised. The viscosity of diesel fuel is also measured. Because #1D diesel is thinner, it flows more freely within the engine. During cold temperatures, Diesel #1D is also less likely to thicken or turn sludge-like. In cold conditions, the higher chemical volatility, which is generally a hindrance, becomes an asset since it ignites much quicker during compression. During the winter months, many stations will provide a blended Diesel #1 and Diesel #2 choice, despite the fact that Diesel #2D is the most popular diesel fuel option.
7. Use Winter Fuel Additives: Winter blend diesel fuel additives may be purchased at most gas and service shops and added to your diesel fuel. The Cold Filter Plugging Point (CFPP) is a standard test that determines the rate at which diesel fuel will flow through a filtering device under cooler circumstances. A Low Temperature Flow Test (LTFT) is also available, which evaluates the operation of diesel engines with no or inappropriate additives in the fuel lines. It’s worth noting that the Pour Point is the third and final test for determining how effective diesel fuel is at working in freezing temperatures. The Pour Point refers to the temperature at which diesel fuel loses its liquid form and pumps cease to function.
When a diesel engine is started in a cold temperature environment, it may operate for a period of time below its Cold Filter Plugging Point (CFPP). When this temperature is reached, the fuel from the injector pump and injectors stops flowing, and the spill is returned to the fuel tank. Cold Filter Plugging Point Additives keep fuel from freezing in lines and gelling in the engine and gas tank. Fuel will be released to the injectors after the temperature has warmed up again.
8. Mix Additives During Fueling: These additives will only work if you add them above the Cold Filter Plugging Point (CFFP). At warmer temperatures, the additives need time to mix with the fuel. On a cold day, the additives should be added right after filling up with Diesel #1D at a service station. The heated diesel fuel straight from the pump should be warm enough to adequately combine the two solutions. Choose an additive that is rated at least 10 degrees cooler than the temperature you expect to encounter if you want to drive long distances in the winter.
9. Do Not Combine Additives With Winterized Diesel Fuel: Diesel additives are not a panacea for cold-weather problems. The additives will only prevent the formation of big gel particles in the engine, which could clog the fuel filter. Regardless of the temperature or additives employed, some gelling will occur. You should not add any additional additives to a gas station’s winterized diesel fuel (not to be confused with mixed diesel fuels). Incompatibilities with a variety of additives may cause the fluids in the fuel blend to degrade, obliterating any benefits.
If you suspect the fuel has gelled, replace the fuel filter. Wait for the temperature to raise or use a block heater to warm up the engine if you fear your diesel fuel has gelled before attempting to start it. On older vehicles, a gel in the fuel filter might obstruct the passage of fuel from the tank to the injector pump, requiring quick replacement. Because they are managed by the ECM, common rail injectors are less prone to gelling.
11. Keep Your Diesel Equipment or Vehicle in a Heated Location: It may seem obvious, but even a few degrees warmer might be the difference between a vehicle that starts and one that doesn’t.
On cold days, if at all feasible, keep trucks and tractors in garages, barns, or sheds. Consider utilizing a block heater on a timer a few hours before use to save time. It may not be a quick fix, but it will assist in getting the engine started.
12. Allow Engine to Warm Up Before Putting It Under Load: Allow the engine to warm up for 5-10 minutes before putting it under load. The harder internal parts of the engine are put under higher stress when the engine gets colder (camshaft, crankshaft, connecting rods etc…) The oil temperature will reach appropriate levels and effectively lubricate the engine after only a few minutes of warming.
How do I know if my fuel line is frozen?
How can you know if your gas line is frozen?
- The engine will not start. This usually means the lines have frozen solid and no fuel is going to the engine to start the car.
How do you start a car with frozen fuel lines?
How to Start a Car When the Gas Line Is Frozen
- Heat the fuel line with a hair dryer. If you’re familiar enough with autos to locate the gasoline line, use a hair dryer to melt the ice.
- Warm up the entire vehicle. Bring your car into the garage and turn on the space heaters so they are aimed towards the engine.
What temperature do fuel lines freeze?
Your gas will not freeze solid in your gas tank or fuel lines unless the temperature is much below -40°F. Extreme temperatures, on the other hand, can cause it to crystallize. The gasoline filter will pull out those gas crystals, however this may cause your fuel filter to clog. While most gasoline already has antifreeze additives, you can add isopropyl gas antifreeze or just normal isopropyl alcohol for more assurance. You’ll need 12 ounces per 10 gallons of petrol, plus or minus a couple of gallons. One bottle of store-bought isopropyl antifreeze would enough, and it normally costs between $2 and $3.
Then Why Won’t My Car Start?
Extreme cold has a considerably higher chance of affecting the battery. Your vehicle’s alternator and starter will not work if there is no power. If you don’t have a battery, you won’t be able to start Carry jumper cables with you at all times to avoid becoming stranded. Having a cold-weather battery with high cold-cranking amp levels is the only way to ensure you use them as little as possible. Two cold-cranking amps per cubic inch of engine displacement is recommended by experts. If figuring it out and installing it seems too difficult, we can help.
At what temperature does diesel fuel start to Ungel?
When the temperature of diesel fuel drops, the paraffin that is normally contained in it begins to harden. The wax in liquid form will solidify at 32 degrees, clouding the fuel tank. It will ultimately start to gel at 10-15 degrees and block the tank and fuel filters.
