Firefly Fuel Clean Fuel Lamp Oil - Smokeless, Virtually Odorless, and Long-Lasting Burn Time for Indoor & Outdoor Lamps - 32 Ounces - Made in USA

I am sitting here right now burning Firefly CLEAN Fuel Lamp Oil in my brand new Vermont Lanterns Brass "Dorset" Table Lamp (8", Antique Brass). So far now from what I see this is a match made in heaven! :) I see and/or smell NONE of this alleged soot or smoke that I have read about by a very small number of people. I believe their problems are from improper use of this fine product. (operator error) I will continue to order this lamp oil provided the price does not go up. (note that this was a Prime item when I ordered it, so free shipping. However looking at today's listing it does not appear to be Prime anymore and I see they tacked on a $7.77 shipping charge.) I will wait until it is Prime again because I am not willing to pay that price for it. Firefly don't shoot yourself in the foot on shipping charges. Things I like: I like that this is probably the safest lamp oil on the market with regard to flash point, the temperature at which it ignites is a high 220 degrees so there is less worry about storing it in the house. I like that this is a high mileage fuel that burns 50% longer than competing products. I like that it is burning nicely in my lamp without any issues. I like that I don't smell anything at all about this lamp oil, either before burning, while burning, or after burning it. AFTERTHOUGHT: If you are interested in using this fine lamp oil you should take some things into consideration while using it. It will arrive to you with totally no scent or detectable smell. If you mix this lamp oil with kerosene (which you should never do) , you are messing up a good thing, it probably won't burn right, and the kerosene or other bad smells you smell will be from the kerosene, not this lamp oil. (Then you will blame this lamp oil for the smell, and that is just WRONG!) If you get this oil and plan to start using it you should empty out the oil lamp or lantern you are going to use it in and turn the lamp or lantern upside down on some paper towels (lamp opened, of course), for an hour or so and let all the old oil drip out of the lamp onto the absorbent towels. Then take a clean towel and wipe any remaining oil off of the lamp. At this point if your lamp's wick has ever been used before for kerosene or even another brand of lamp oil you should replace it with a new unused wick immediately before burning this oil. (remember you don't want to smell that old kerosene, right?) Not only that but by putting the old kerosene-laden wick back into the lamp the kerosene in the old wick will contaminate your brand new lamp oil, making for you an unpleasant experience. If you use this lamp oil correctly, (and uncontaminated), you will have a very pleasant experience.

I really like it it does what it's supposed to do and does it very cleanly. Burns well with no odors. I must buy right now don't wait buy extra in case the world goes even more crazy

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.

I have a lot of lamps that I burn for maybe three hours a night most nights. So I go through a lot of this stuff. It burns clean and with minimal smoke, certainly less smoke than candles do. However. This oil is about 25% more expensive than the best of the paraffin oils on the market. They talk a good deal about how they have a special product that is greener, more efficient, longer lasting, cleaner burning, and so on, than these paraffin oils. But nowhere can I find anything that explains how their oil accomplishes all these better-than-paraffin things, and I've spent some time looking. I'm beginning to think that the "secret" of this oil is that it's really the same old paraffin that you can buy for 10 bucks less a gallon anywhere else, with a "here are all the reasons our dimes are better than other dimes" sort of marketing campaign tacked on to it to justify the higher cost. I'm experimenting with other brands to see if I can find any differences in how they perform. Edit: I spent two or three months using the Shabbos paraffin oil (price $28.99 a gallon, or $10 cheaper than Firefly). I found the burn quality to be comparable with the Firefly oil. However, I got the feeling that my lamps ran out a bit quicker with the Shabbos. So, I bought a gallon of each, and did a comparison of burn times between Shabbos and Firefly lamp oil. I filled my smallest lamp with Shabbos oil, lit it, and timed the burn time with a stopwatch. I then did the same with the Firefly oil. The results were that the Shabbos burned out in 5.5 hours, while the Firefly burned out in 7.25 hours. Now, I didn't measure the oil, and I adjusted the wick a little bit between the two burns, so it wasn't a rigorously controlled experiment. But I think it's safe to say that the Firefly oil burns significantly longer than the Shabbos. Now, the Firefly is about 34% more expensive, and it burned about 32% longer in my experiment. So, they're about the same cost to use. However, I don't have to fill the Firefly lamps as often, which is a benefit to me. I'm changing my review from three stars to four. If it were a few dollars cheaper, I'd give it five.
