How Do I Keep My Diesel Fuel From Gelling?

One of the best methods to avoid fuel gelling is to keep the fuel from becoming too cold, which you can accomplish by not leaving your car outside in the cold. This technique should work in the winter if you have a heated garage or other form of climate-controlled storage facility for your vehicle. Because the fuel won’t gel while the engine is running, you can still drive the automobile in the cold. If you have to leave it outside for several hours or days at a time, you’ll need to find another technique to keep the fuel from gelling.

What can I put in my diesel fuel to keep it from gelling?

You get ready to go to work one morning, but your car won’t start. Overnight, your fuel in the tank has solidified. So, what exactly do you do?

For truck drivers, the winter months are more than just a dangerous time when they must drive extra cautiously. In fact, the colder months bring with them a slew of new issues, one of which being diesel fuel gelling. 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 filter.

The gel point of diesel is the temperature at which it solidifies and can no longer flow through the fuel lines. The pour point, on the other hand, specifies the temperature at which a fluid begins to harden.

This is the most important one. The diesel fuel in the fuel lines has solidified and clogged the fuel filter. The engine will not start if petrol cannot enter through the fuel filter.

Some truck drivers have told us about filling up with diesel fuel in the winter and neglecting to add anti-gel treatment. When they get on the road, they discover that their vehicle is at best sluggish, and that it can’t even accelerate correctly. When accelerating, a mismatch between the intended fuel rail pressure and the actual rail pressure is detected. Because of the gelling of the diesel fuel, the required pressure frequently jumps while the actual pressure remains low, preventing the fuel from getting where it should go.

Truckers frequently mix #1 diesel, which has a kerosene blend, with diesel #2, which is utilized for road applications. Kerosene lowers the plug point temperature of the fuel and reduces its viscosity, reducing the likelihood of diesel gelling even at low temperatures.

Another typical option for diesel fuel gelling is additives and fuel treatments. They function in a similar way to the previous alternative in reducing the production of paraffin crystals. They also help to reduce the fuel’s pour and gel points. For than two decades, AFS products have reliably and affordably protected New England and Mid-Atlantic diesel enthusiasts with its patented cold weather innovations and comprehensive fuel oversight programs.

Our Winter Diesel 2010 Additive, which combines wax modifiers and wax anti-settling chemicals to improve low-temperature operability, is a good example of a fuel treatment. While ensuring fuel economy and emission management, it also provides L10 injector detergency, fuel stabilization, and corrosion inhibition.

Our technical staff is available to discuss any issues you may have about winter operability with you. They can provide advice on best practices and preventative measures that will help you and your customers prepare for whatever the winter brings.

What causes diesel to gel?

Fuel Gelling: What Causes It? Temperature effects on paraffin, a component of diesel fuel, are the most common source of gelling difficulties. When paraffin waxes are burned in an engine, they produce more power. Diesel, on the other hand, will begin to harden as the temperature drops.

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 you add gasoline to diesel to prevent gelling?

Get in your gas pickup and head north to a truckstop to purchase anti-gel or #1 fuel. However, do not add gasoline to your fuel system or engine.

Plug in your truck or vehicle

You can use an engine block heater to prevent a diesel vehicle from gelling. These can be installed at your local dealership if your truck doesn’t already have one.

Use winterized diesel.

Some gas stations will have fuel that has been winterized. It may not be available at every pump, so call ahead or inquire at the gasoline counter. They might have a blend that lowers the gelling temperature significantly.

Keep diesel tank as full as possible

Keep more than half a tank of gas in your car. If you’re traveling long distances in places like Wyoming, this could be difficult. With more fuel in the tank, the chance of water/condensation collecting and freezing is reduced. This, in turn, will aid in the prevention of diesel gelling.

Store the vehicle inside

Keep your car in the garage (heated is even better if you have one!) as much as possible. Keeping the vehicle inside, though, may provide just enough of a temperature differential to prevent gelling.

Do gas stations add anti gel to diesel fuel?

One of the most significant disadvantages of diesel fuel is that it does not perform well in cold weather. When I say it doesn’t play nice, I mean that the cold can be a pain in the neck. Diesel fuel can create waxy solid crystals that clog gasoline lines and filters when temperatures drop. This not only prevents engines from starting (or from starting and then dying), but it can also necessitate major repairs if things go bad enough.

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.

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.

What does it mean when a diesel is gelled up?

Wax particles form in the gasoline, which causes it to gel. The diesel comes to a complete halt. The main problem with this is that the fuel cannot flow correctly through the engine and fuel lines. Not only will the equipment be rendered useless, but the gasoline lines and engine may be destroyed as well.

What can I do with gelled fuel?

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.
