How To Thaw Diesel Fuel Lines?

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.

Emergency CleanBoost Diesel Rescue De-GelTM was created with one goal in mind: to get you out of an emergency situation and back on the road as quickly as possible. Continue reading.

How long does it take for fuel lines to unfreeze?

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.

How long does it take gelled diesel to thaw?

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!

Product Details

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.

Will diesel fuel Ungel when it warms up?

While gelled fuel sounds horrible, the good news is that if the temperature rises over the gel point, diesel fuel will revert to normal. Typically, all that is required to resolve the gelling issue is to drive the vehicle into a garage and leave it there for a few hours. If the temperature isn’t projected to rise soon or you don’t have access to a heated facility, there are some additional options.

How long does it take to Ungel diesel?

In diesel fuel, a similar process occurs when the fuel crystallizes during cold weather. Gelling begins to occur when the temperature approaches 10 to 15 degrees Fahrenheit*, which can block the fuel system (*depending on the supply and quality of fuel, gelling can occur as high as 20 degrees Fahrenheit).

How To Tell When Diesel Fuel Begins To Gel

When diesel fuel begins to gel, Berg says there are a few telling indications, the most obvious of which is a loss of power and compression when fuel fails to reach the combustion chamber. If you could see the gasoline, it would have a hazy appearance, indicating that it had already gelled. Other indicators to look for include white smoke coming from the exhaust when trying to accelerate or the engine stopping running when you are sitting idle trying to throttle. Also, if the vehicle starts but does not run continuously, this could indicate that your fuel has gelled. Gelled diesel fuel is almost always the problem, whether it’s a lack of RPMs when an engine is running or a cold winter morning when the truck won’t start at all.

How to Fix Gelled Diesel Fuel?

Many people make the mistake of grabbing a can of ether to start the combustion process when their diesel vehicle won’t start at all. However, there are certain risks with this solution, as there may not be enough fuel to ignite. Spraying too much ether and having ether spray that isn’t contained causes even more issues. The uncontained spray might ignite other hot components, causing engine damage, or too much ether in the fuel line could simply ignite air in the lines rather than gasoline, causing the diesel engine to suffer severe damage. Fortunately, there are alternatives to spraying ether that are far safer. Here are a few preventative measures to consider:

  • Heat is the most effective line of defense. Avoiding frigid conditions by storing your vehicle in a climate-controlled garage or warm area. Other strategies include installing a series of heat-emitting light bulbs under the vehicle, enclosing the vehicle in a tarp with a heater blowing heat, and installing a modern-day block heater on the engine to keep the vehicle sheltered from the freezing temperatures. While building up the electric costs, the utility providers will adore you as well.
  • Kerosene: With the issue of staying warm when it’s 20 degrees below zero, people might experiment with different fuel mixtures. Pouring kerosene into the fuel tank to lower the freezing point is the most typical method. To take advantage of kerosene’s lower freezing point, many people mix #1 diesel, which is a combination of kerosene and #2 diesel fuel. This mix is frequently accessible in the northern parts of the country, but in the southern parts of the country, where temperatures are normally warmer, the #1 diesel may not be available. In either instance, kerosene has drawbacks, the most notable of which being reduced fuel mileage and efficiency. If, on the other hand, the truck stops running and kerosene is chosen, it is strongly recommended to leave the engine run long enough to combine the fuels and provide a continuous flow of the mixture. Consider the time it takes for the kerosene to defrost the tank in a semi-truck when operating with hundreds of gallons of fuel in a tank. The kerosene must next melt the frozen fuel lines and clogged fuel filter. The entire line from the gasoline tank to the filter to the injectors may take an hour of idle time to defrost.
  • Fuel Additives: There are now fuel additives that can provide a simple, low-cost, and no-hassle method to prevent gelling that any car owner can do themselves. “When considering an addition, Berg advises, “do your homework and analyze all of the products and promises.” “Investing a bit more time and effort to discover the greatest product is occasionally worthwhile. Additives are a means to offer an extra layer of protection to prevent the wax in diesel fuel from becoming thick, similar to wearing layers of clothing in the cold.” Many products contain alcohol, according to Berg, so look for one that provides not just proper temperature coverage but also protection for the entire system, including lubricity, cetane, water dispersion, and a success guarantee. Many preventive options are available, including some top picks being Diesel Winter Anti-Gel, which promotes coverage down to -40°F.

How to Prevent Diesel Fuel Gelling?

So, what’s the big deal about taking the effort to prevent diesel fuel from gelling? “If you contact a tow truck, you may still be stuck with a vehicle that won’t start after paying the tow cost,” Berg explains. You can save yourself the $80 and the headache in the case of a personal or light-duty car, or the $500 tow bill and missed time on the interstate in the case of a truck. Instead, taking use of the finest scientific additives could safeguard you from getting stuck in the cold for only a few dollars in preventative and an easy pour into the tank.

Emergency additions are also available for people who have failed to heed the warning, there has been no prevention, and gelling is still a possibility, or has already occurred! Diesel Winter Rescue, for example, is a formulated substance that requries gelled fuel and de-ices frozen fuel filters to restore diesel fuel flow to the engine, allowing the vehicle to resume normal operation. Diesel Winter Rescue, for example, is a good alternative to keep in your vehicle during the winter months just in case.

Can you use gas line antifreeze diesel?

TURBO POWER Universal Gas Line Antifreeze is ideal for many sorts of automobiles, including those with fuel injection, carbureted engines, and diesel engines. It is suitable for automobiles, trucks, motorbikes, and snowmobiles.

Antifreeze for gas lines helps to dry up moisture in gasoline tanks and lines and keeps them from freezing. It also makes it easier to start in chilly weather. To assist prevent human or animal eating, this product contains methanol and an efficient bittering ingredient.

For 60 litres of fuel, use roughly 150 mL of gas line antifreeze, or one full 150 mL bottle every tank of gas.

TURBO POWER Fuel Injection Gas Line Antifreeze boosts engine performance, ensures quick starts after a long period of storage, and keeps water out of fuel tanks. It may be used with all grades of gasoline and diesel fuel and helps to keep carburetors and fuel systems clean.

Fuel Injection Gas Line Antifreeze is made from ethanol and does not include any methanol. It’s great for powerboats, RVs, gasoline lawnmowers, and snowmobiles, and it’s recommended for cars with fuel injection systems.

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.

How do I keep my fuel lines from freezing up?

How to Keep Your Car’s Fuel Line From Freezing

  • Maintain your car in a garage that is secluded from the rest of the house to keep the temperature above freezing.
  • Maintain a fully charged battery in your vehicle; this will enhance the engine’s rotation rate.

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.
