Cold weather is tough for diesel engines, but as temperatures drop into the teens below zero, diesel owners must contend with fuel gelling issues. Untreated diesel gasoline begins to gel at 32 degrees Fahrenheit and is entirely gelled at 15 degrees Fahrenheit.
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 do you quickly Ungel 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.
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 cold does it have to be for diesel to start gelling?
- Gelling: It’s unusual to have a situation where the fuel practically turns to jelly. Gelling happens when the paraffin wax in diesel solidifies due to a drop in temperature, and the fuel’s temperature must be kept below minus 10 degrees F for extended periods of time, such as 48 to 72 hours. When diesel is cold soaked, the paraffin wax in the fuel hardens, giving it a hazy look. At temperatures as high as 32 degrees F, the fuel will begin to cloud, but it will continue to flow. Before the fuel can gel, it must be kept at a very low temperature for an extended period of time. It’s common to hear drivers complain about their fuel gelling up, but this is almost certainly not the issue they’re having. Ice or solidified paraffin wax in the fuel filter is more likely to be the issue. There’s more on that later.
- Cloud Point: To determine the cloud point of a sample of diesel fuel, which is the temperature at which the naturally present paraffin wax in #2 diesel fuel begins to crystalize, there are prescribed methods. The fuel has a hazy look due to the microscopic particles of suspended hardened wax. Cloud point temperatures for diesel fuel typically vary from -18°F to +20°F, but can reach +40°F depending on a variety of factors connected to the base stock and refining operations. The cloud point of so-called winter diesel fuel (#1 diesel or kerosene) is substantially lower since it contains relatively little paraffin. Fuel distributors will test the product and, if requested, may include the results in tenders and delivery receipts.
- The temperature at which a liquid loses its flow properties is known as the pour point. The pour point of diesel fuel changes according on the wax content in the fuel, which varies depending on the source of the base stock, the refining process, and the type and quantity of additives added to the fuel during refining or distribution. The difference between the cloud point and the pour point is always there, with the latter often being 2° to 20°F lower than the former. To establish the pour point of a fuel sample, certain tests must be performed. Bulk providers, as previously stated, can supply this information.
- When diesel fuel is cooled, the cold filter plugging point is a measurement based on a standardized test that indicates the rate at which it will flow through a standardized filtration equipment in a given amount of time. The CFPP is the point at which the sample fails to pass through the filter in the time allotted.
Gelled Fuel in The Fuel Tank:
If the fuel in the tank has gelled, add the entire contents of Diesel Winter Rescue (32 ounces) to every 40 gallons of fuel in the tank (s). Remove the fuel filters and fill them with a 50/50 mixture of Diesel Winter Rescue and diesel fuel. Start your engine after reinstalling the fuel filters. Allow your engine to idle for a few minutes to warm up the fuel system and clear any gelled masses.
Gelled Fuel in Fuel Lines or Fuel Filters:
Remove the engine’s fuel filters and fill with the same 1:1 combination of Diesel Winter Rescue and conventional diesel fuel if your fuel is liquid in the fuel tank(s) but your engine won’t start. Reinstall the fuel filters, start the engine, and let it warm up completely.
How Do Hot Shot’s Diesel Winter Products Work?
Hot Shot’s Diesel Winter Rescue is a fully developed emergency product that contains a military-grade de-icer as well as a lubricity additive for diesel fuel. It’s designed to re-liquefy gelled fuel and de-ice frozen fuel filters, restoring diesel fuel flow to the engine and allowing the vehicle to resume normal operation. Having products like Diesel Winter Rescue in your vehicle during the winter months, when gelling is most likely, is a good idea.
Can gelled diesel damage injectors?
The gelling, on the other hand, might not be enough to damage an injector. In other words, it gelled, and you didn’t try to run it again until it ungelled. However, if the fuel leading to the injectors has gelled up and the FICM is driving them, the injectors will be starving for fuel. It’s the same as if you were in a low (or no) pressure situation.
At what temp will diesel fuel gel?
This phrase is self-explanatory, as fuel gelling occurs when the petrol in your tank thickens to the point where it resembles gel. This only happens when the outdoor temperature dips below 32 degrees Fahrenheit, though it’s most likely to happen when the temperature is around 15 degrees or below. This is due to the presence of paraffin wax in diesel fuel. When you need to improve the lubrication and viscosity of the gasoline, that’s a terrific ingredient to have…but it’s not so great when the wax thickens as it gets colder.
As a result, the thicker fuel clogs the filters and eventually stops flowing completely, preventing you from starting your vehicle. So, how can you tell if your car is experiencing fuel gelling? If it’s below freezing outside and your diesel-fueled vehicle won’t start, it’s most likely due to fuel gelling. Fortunately, this common diesel fuel winter issue can be avoided. To be more specific, there are two basic strategies to avoid this problem.
Can you put too much anti gel in diesel?
Is it possible to use too much anti-gel in diesel? You’ve probably added much too much high-quality diesel fuel additive. Overloading your engine can result in clogged filters, reduced engine performance, and potentially a whole new set of fuel and engine issues. If you’re losing your libido, don’t overdo it.
What temperature does offroad diesel gel?
When the temperature drops, the paraffin in diesel fuel begins to harden, resulting in diesel fuel gelling. 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.
How can I make my diesel engine warm up faster?
Gelled gasoline and electrical failure are the two most common reasons why people have problems with cold diesel engines. Cold diesel engine-powered apparatus must therefore be adequately maintained before being exposed to freezing temperatures. With that in mind, here are six recommendations for starting a diesel in cold weather and keeping your equipment in good working order over time.
Do Not Underestimate Warm-Up Time
It’s critical to allow your cold diesel engine to warm up. Allow your equipment to warm up for at least five minutes before using it; this will allow the hydraulic oil to warm up. If you don’t, the engine will have to work more than it needs to.
Consider Heating Options
When it comes to heating your gear and keeping it working properly, you have various alternatives.
- An electric block heater heats the coolant in the system, which warms the engine block and oil in the crankcase. This makes it easier for the engine to flip over.
- A diesel-fueled coolant heater can be used to warm up your engine in areas where power is not commonly available.
- Glow Plugs: These can aid in the ignition of cold gasoline and also heat the fuel-air combination inside a large engine.
- A Battery Tender: As the temperature drops, the cranking amperage of equipment batteries decreases. While machinery is susceptible to this type of failure, a battery tender will continue to function as long as it is fully charged. Battery cables should be checked before winter for owners of cold-diesel equipment. A battery’s ability to start machinery is harmed by bad connections.
Keep Your Diesel Exhaust Fluid Thawed
If you plan to add DEF to your apparatus later, keep it above 12 degrees Fahrenheit to prevent it from freezing. Although freezing does not reduce the uptime of your equipment, keeping DEF on hand ensures that it is ready to use when needed.
Address Frozen Fuel
During the winter, diesel fuel creating wax crystals is a more usual impediment to machinery starting smoothly. Fuel filters will become clogged as a result of the contaminated fuel, and the engine will not start. Using winter-blended diesel fuel, which lowers the temperature at which these crystals form, is one technique to prevent crystals from forming in the gasoline.
According to the University of Tennessee Agricultural Extension Service, if your fuel has frozen or gelled together, you should change the fuel filter and reheat the fuel before starting the engine. This prevents the frozen fuel from obstructing the flow of fuel from the tank to the injector pump.
Keep Your Engine in a Warm Area
If at all possible, keep your diesel engine in a warm place away from the elements like sleet and snow. Keeping the engine in a warmer environment, even if it’s only a few degrees warmer, can help it warm up faster.
Make Sure Your Fuel Tank is Full
Condensation in a fuel tank can eventually freeze, causing difficulties similar to gelled fuel. In the winter, keep your fuel tank as full as possible to prevent condensation from forming. A winter diesel fuel additive may also help to prevent your gasoline from freezing up.
