Burn-Time Comparison

Fuel Oz. Burn Time – Hours Burn Time – Minutes Burn Time Per Ounce % Increase
Firefly Paraffin lamp Oil 3 4:35 275 92 minutes 0%

  • Less Expensive and much longer lasting than Paraffin Oil Lamp Fuel (Be sure to view the time-lapse videos)
  • Virtually ODORLESS
  • Clear and CLEAN Burning
  • Will NOT Freeze
  • Available pure, with Citronella Oil or Eucalyptus Oil
  • Great substitute to Paraffin Fuel
  • If you are going to use in a large-wick device like a tiki torch, the fuel will produce some smoke and is not entirely smokeless. Keeping the wick as low as possible will reduce fuel consumption and smoke.

One of our customers wrote about our CLEAN Fuel with Eucalyptus and Citronella Oil – “Your products are magnificent. I’ve used them in Candle Lanterns instead of wax candles and in small lanterns. Absolutely no smoke or soot. Exceptionally clean fuel that kept the bugs away. Thanks for making such a great product.”


Our Clear CLEAN Lamp Oil is a True Alternative

Firefly Fuel brings to market a new Clear, CLEAN fuel as a DIRECT REPLACEMENT for paraffin lamp oil.

Firefly CLEAN fuel is non-smoking, sootless, odorless, provides a great flame and is longer lasting than paraffin oil. Firefly CLEAN Fuel is just a simple, safe product.

Firefly CLEAN Lamp Oil is a direct replacement for paraffin fuel with the same operating characteristics (smokeless, odorless and clean-burning) plus many notable improvements.

• Firefly Clean Fuel Benefits vs. Paraffin Oil

• Less Expensive than Paraffin Oil

• Availability Always readily available.

• Increased Burn Times– In-house testing showed CLEAN fuel burned 50% longer than our paraffin lamp oil for even greater economy (results may vary)

• CLEAN Lamp Oil will NOT freeze.

The optional additives we offer to the base odorless fuel are Citronella and Eucalyptus oils. These oils assist in deterring insects when mixed with our Firefly CLEAN fuel.

Available with Citronella Oil or Eucalyptus Oil to help Deter Mosquitoes

The base fuel is virtually odorless. The fuel is available pure or we add Citronella Oil or Eucalyptus Oil to help deter mosquitoes which adds a hint of a pleasant scent.


 Firefly CLEAN Lamp Oil works well in oil lamps, lanterns and oil candles. It is not suggested for vessels that use a large wick like tiki torches as it will smoke.

I’d like to give you some important tips so that you can get the maximum performance from Firefly Fuels.

All Firefly Fuels require a wick to burn and are combustible, not flammable. Our fuels should not be used in vessels that require alcohol-based fuels.

1) Remove old residual fuel from the fuel reservoir before filling with Firefly Fuel. It doesn’t need to be dishwasher clean, but you certainly don’t want to mix fuels together. Mixing fuels will change their burning properties and may cause excessive smoke.

2) Use a clean wick. The wick is the delivery vehicle for the fuel. If the wick is contaminated with old fuel or water, it will not perform properly. In a pinch, if you only have one wick, the following steps have worked well for our customers. 1) Dry the wick as much as possible using a paper towel. 2) Soak the wick in Firefly Fuel until it is completely saturated. That’s it!

3) The wick should be as low as possible. This will reduce smoke, provide a more consistent flame and conserve fuel. When I say low, I mean just barely above the wick holder. Within 5 minutes your flame will reach its maximum height.

4) When we add citronella or eucalyptus oil to the fuel, it is for the purpose of helping to deter bugs. The base fuel is odorless; however, adding the oils provides a mild scent of either citronella or eucalyptus. For those wanting a stronger scent, we have designed 2 patented aromatherapy candles, the Zen and Zen Petite. These candles allow you to add essential oils to the “Aroma Deck” which throws the scent. The benefits are…1.) You will use considerably less essential oil to achieve a strong scent. 2.) You will not contaminate the fuel, and it will burn cleanly. 3.) You can easily change the scent.

5) FYI. Why is there a stream of smoke when blowing out a flame? This stream is vapor that has condensed into a visible form. It continues to form as long as the wick is hot enough to vaporize. If you touch a lit match to the stream, a flame will run down it and re-light the wick.

6) Excessive smoke can also be caused by wind which inhibits the fuel from completely burning.

7) If you are purchasing a 5-gallon container, Here is a BLOG POST showing how to install the spigot into the 5-gallon container for easy access.

    5.0 out of 5 stars – Find me those old lanterns!
    July 16, 2016
    Size: 1 Gallon|Color: Clear | Verified Purchase
    My mom brought me two Dietz lanterns that were once used by her father. He used them in the winter to put in the pump house to keep the pipes from freezing. He also burned kerosene in them and over the years they became quite dirty. After he passed away, my mom used them as decorative pieces on the mantel of the fire place and they haven’t been used in 40 years. They were in very good shape, for their age, and I spent some time taking them apart and cleaning them. I didn’t want to restore them to “brand new” condition as I thought that the paint scuffs and other age related imperfections gave them a bit more character. After getting them functional again, I decided to use this particular fuel by Firefly in the hopes that it would be better for the lanterns instead of using kerosene. I also didn’t want to deal with smoke getting everything dirty again and the smell of kerosene isn’t exactly pleasant. I’m happy to say that this fuel has worked amazingly well for the old lanterns. It has no odor and only produces smoke if I start raising the wick really high. It was amazing to see the lanterns working again and as a kid, I thought that they were only non functioning decorative pieces. We probably spent a few hours in the garage this evening watching them glow and talked about our grandfather, as well as, the history of these particular lanterns. Now I’m on the hunt for another lantern that I remember seeing hanging on the wall of one of our old barns back home. If I do find it, and I can get that one fixed up again, I will definitely be using this fuel in it as well.
