Imagine a snowy night and just when you get the kerosene heater you realize you’re running out of kerosene. You check again and find some diesel in a gallon just behind your truck.
Or maybe it’s just a cold and while you can step out to get more kerosene, you don’t intend to spend all that money and you’re not even sure you’ll get some as kerosene is getting increasingly hard to find and more expensive by the day.
Then you ask the crucial question, “Can I use diesel in my kerosene heater”?
Yes, you can use diesel in your kerosene heater for the simple reason that the typical kerosene heater is built to accommodate different types of fuels.
Though you can use diesel in your kerosene heater, you need to be careful about how you go about it, because different types of diesel will give you different results and using the wrong one may affect your health and your heater as well.
We’ll tell you all you need to know about this as you read on, including how to safely use diesel in your kerosene heater.

Top 3 Kerosene Heaters
What Fuel Can Be Used in A Kerosene Heater?
Ideally, the recommended fuel for kerosene heaters is kerosene, specifically K-1 kerosene. This is a high-quality fuel that burns well and burns very clean too.
While lesser quality fuels like diesel, or even some alternative oils like vegetable oil may be used in some way, they may cause some problems if not done the proper way.
It is true that any type of diesel can be used in place of kerosene, but you’d need to consider a few things and use them properly. Specifically, it is better to use Number 1 diesel than any other type, because it is the closest to kerosene in terms of similarity.
ULSD heating oil or vegetable oil is another option. Long before kerosene was invented, people used vegetable oils for powering their lamps.
It is quite easy, clean, natural, and non-toxic. However, you’d need to be sure your heater is one that can run on vegetable oil.
Is It Safe to Burn Diesel Fuel in A Kerosene Heater?
It is quite safe to use diesel fuel in a kerosene heater if you do the right thing.
For instance, using Number 1 diesel is better because the paraffin wax has been taken away, making it burn cleaner than other types like Number 2 diesel.
This makes it move up the wick better and you won’t have to worry about gelling in the cold. Using the wrong kind of diesel may cause some problems.
This is because diesel burns cooler and is likely to release much more carbon which may affect your health. There’s also the issue of viscosity and the inner lining of your heater may be affected.
Another way to safely use diesel in a kerosene heater is to add some additives. Adding additives will ensure it burns cleaner and doesn’t destroy the wick too quickly. Some recommended additives include;
1. Isopropyl Alcohol
This should not be lower than 91% in purity. You’ll find them in most stores and pharmacies, usually beside the hydrogen peroxide bottles. Add 5ml of Isopropyl Alcohol to every 1 pint of diesel for best results.
2. Kerosene Additives
This is another option originally made to be mixed with kerosene for cleaner burning, but they can be a useful additive for diesel as well. Each Product should have recommended quantities on the bottle, so you should do as directed.
This is, perhaps, the best thing to do. Kerosene is about 3-4 times more expensive than diesel and mixing both fuels for your heater may just be the best way to save cost.
You can fill ¾ of the heater tank with diesel and fill the other ¼ with kerosene or do a 3:1 ratio mixture before adding it.
If it’s a lantern-style heater, be sure that it’s a wick you’re burning and not a candle, because a candle will burn much faster. This is important whether you’re using kerosene or diesel.
However, it is best to use 100% cotton wick when burning diesel in your kerosene heater, because it burns pretty well and you’re able to trim off the tip in the event it’s covered up in carbon. Fiberglass and other materials may work well when burning kerosene, but not diesel.
