Cold Weather Fuel Challenges: Diesel vs. Kerosene

How can you get the best performance from your on-road and off-road diesel?

As the end of the year approaches, countless businesses, farms, work sites, and vehicle fleets are preparing for the winter in Massachusetts. This time last year, we were about to enter one of the most frigid periods our region had seen in many years. The prospect of these freezing conditions presents a lot of challenges — including how your diesel will hold up.

For over a century, the Atlantic-Pratt Energy team has provided top-quality diesel to municipalities, businesses, marinas, fleets, and job sites. We appreciate the concerns our clients face around winter. Many want to know if kerosene is a viable replacement for diesel in freezing conditions.

What Are Diesel’s Cold-Weather Issues

When temperatures drop to about 20°F and lower, diesel fuel (including on-road diesel, off-road diesel, and heating oil) can begin to “gel.” That means that the paraffins in the fuel begin thickening. Diesel becomes thicker and less combustible, and it can begin clogging your lines and potentially damaging your equipment.

What Is Kerosene?

Kerosene is a refined fuel produced by distilling crude oil at high temperatures. It has a low gel point and performs reliably even in freezing conditions, making it useful for outdoor fuel tanks and winter use. Often blended with other petroleum distillates, kerosene serves a variety of purposes — from space heating to jet engine fuel and industrial solvent applications.

Can You Use Kerosene in Diesel Equipment?

You should not assume that you can blend kerosene with your diesel or use it in place of diesel. Kerosene may be a fuel oil that is comparable to diesel fuel, but it has some crucial differences, including the following:

1. Kerosene isn’t as efficient as diesel and does not provide the same level of lubrication. This can translate to lower performance and even damage your equipment.
2. Using an alternative fuel in your equipment that isn’t approved by the manufacturer can potentially void your warranty.
3. Fuel regulations matter: The fuel you use in road vehicles is strictly regulated. Just like you’re prohibited from using dyed off-road diesel in a truck’s engine, you may face fines for using a kerosene blend too.

At a minimum, you should check your equipment’s user manual and local regulations before considering kerosene as an option for winterized diesel fuel.

Talk to Atlantic-Pratt Energy About Winter Diesel Concerns

There are plenty of other ways to protect your diesel fuel from extreme temperatures and prevent gelling that don’t involve kerosene. You can use anti-gel additives that help stabilize your fuel in freezing conditions without a negative impact on your equipment.

However, it’s crucial to know the ideal ratio for these additives — and Atlantic-Pratt Energy can guide you in this process. Our commercial diesel delivery team knows our fuel inside and out. We’ll provide recommendations to help it stay stable and usable no matter what Old Man Winter throws at us.
