Good!
I use this for cooking on my alcohol stove. Perfect! It does get a lot of soot on my pits but it wipes right off and I prefer to burn this to the other bottle which produces methanol —yuk! Thank you for the quick ship and a good product! I buy this all the time for my alcohol stove and works great! Great value. Sometimes the bottle will leak a bit once the seal is broken so I try to keep it upright after opening. Not leaking at all would be optimal but I haven’t found it any kind of terrible leak. Good product. Good value. Highly recommend for alcohol stoves —but bring some wipes to clean the spot after and don’t touch the pan to your clothes or hands or they’ll be black —but it’s not because it’s a bad product —it’s just the nature of burning it. Lights easily, blows out quickly with a good alcohol burner (I’m using a Triangia with a fire regulator cap attached). This is my go-to fuel.

A Must-Have for Improved Engine Performance and Gas Mileage!
I recently tried **Iso-HEET Water Remover and Premium Fuel Line Antifreeze** and I’m very impressed with the results! I added it to my gas tank as directed, and I immediately noticed a smoother engine performance. My engine starts up more easily, even in cold weather, and it runs much more efficiently overall. I especially love how it helps to remove water from the fuel line, preventing any potential issues with fuel system freezing or corrosion. I’ve also noticed an improvement in my gas mileage. It feels like I’m getting more miles per gallon, which is a great bonus. The **Injector Cleaner** aspect is another huge plus—my car runs cleaner and more efficiently after using this product. At 12 fl. oz., the bottle is the perfect size for multiple uses and gives great value for the price. I highly recommend this product to anyone looking to improve their vehicle’s performance and extend its longevity. Definitely a great addition to my car care routine!

Worth It
Always have a few on hand for the winter as prep for freezing temps. I always make sure my kids have bottles in their cars and use them.

Oh no. There's water in my fuel tank. I can smell it!!
Be careful where you buy your gas. Especially if it has rained recently. Those underground tanks at the gas station build up condensation that drips right into the fuel. This is a good product to remove the water from the gas tank on your car or truck. It's a certain smell. You can recognize that smell when you are filling up your tank. When you smell it, get you some of this product before you run all that water through the fuel system in your car. It's a great product.

This probably works.
My car was acting up after being sitting for so long, it was mispiring but my mechanic recommend this heat and after first bottle the problem went away. The price is also very good and the car runs smoother comparing with other brands.

Can’t Go Wrong
With today’s fuels containing a certain percentage of ethanol which can attract moisture, this product can absorb fuel tank water to keep your gas tank clean. I use it about four times a year & not just during the winter months. Plus it had a fuel injector cleaner as well.
