2) A ‘Winter’ diesel fuel is used from November to April, while a ‘Summer’ diesel fuel is used from May to October (called Diesel No. 1). When diesel fuel becomes cold, it thickens and becomes murky, reducing flow rates through the fuel system it’s like trying to pump molasses through your injectors.
At what temp does winter diesel gel?
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 know if diesel is winterized?
When to Blend 2 Diesel The temperature of 2 diesel is around 14 degrees Fahrenheit. Switching to a winter blend 15 degrees above cloud point is a decent rule of thumb. It’s time to blend in No. 1 when overnight temps drop below 30 degrees F.
How do you start a diesel in the winter?
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.

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.
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.
Will diesel 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.
At what temp does 2 diesel gel?
The cloud point, named after the white haze or “cloud” that emerges as paraffin wax crystalizes, is the temperature at which gelling begins. The cloud point of No. 2 diesel fuel is 14 degrees Fahrenheit.
What’s the difference between number 1 and number 2 diesel?
The fundamental difference between Diesel #1 and Diesel #2 is the cetane rating, which, like the octane of gasoline, indicates igniting ease. It’s all about fuel efficiency, volatility, and seasonality, really.
Less wear on your engines’ batteries implies a faster and more efficient start. The increased cetane grade also helps diesel engines run more smoothly by lowering maintenance requirements.
The additional lubricants in Premium Diesel assist keep fuel system parts moving easily. The fuel pump’s and other fuel system components’ lives are extended as a result of the reduced friction.
Fuel systems can become clogged with sediments and other particles over time. While the engine is operating, detergents are injected to Diesel #1 to clean injectors and other fuel system components. Not only does a clean fuel system last longer, but it also enhances fuel efficiency and horsepower production.
Diesel #1 contains lubricants and detergents, as well as other fuel additives that improve engine performance and save downtime. Even in a well-sealed fuel system, air moisture can find its way in and cause major engine problems. Demulsifiers in premium Diesel work to separate emulsified water from the fuel so that it can be filtered out; even in a well-sealed fuel system, air moisture can find its way in and cause major engine problems. Corrosion inhibitors keep rust and corrosion at bay, while stabilizers keep blockages and buildup at bay.
Diesel #1 is sometimes known as winter diesel since it operates better in colder conditions than Diesel #2. It has a lower viscosity and does not gel when exposed to cold temperatures. Most stations sell a premium Diesel blend that is tailored to the local climate.
While premium diesel has a number of advantages, such as fewer maintenance and equipment downtime, regular diesel is less expensive at the pump, which is an essential consideration. However, total cost of ownership should take into account not only the cost savings from the fuel, but also the impact on ongoing maintenance costs. The age and size of your fleet may play a role in deciding between Diesel #1 and Diesel #2.
When deciding between Diesel #1 and Diesel #2 for your fleet, keep in mind that premium Diesel quality differs from station to station. If you choose Diesel #1, make sure your drivers get their fuel at reliable high-volume stations.

How do I keep my diesel warm in the winter?
In the winter, how do you keep a diesel engine warm?
- Maintain a full tank. Keep the gasoline tank as full as possible to avoid the fuel freezing and gelling.
Do diesels need to be driven hard?
The energy required to push you ahead is generated by burning this fuel in a car’s engine. Because diesel is less flammable than gasoline, it must be burned using a technique known as “compression ignition.” To burn diesel, it must be subjected to extreme pressure.
This pressure, which isn’t required in gasoline cars, puts extra strain on the engine and many of its components. What’s the end result? Parts deteriorate more quickly and fail more frequently.
