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 good product and a good price
We bought these at our local NAPA and they were at least double the price of buying on Amazon. So I am glad I can buy these here. Definitely a good product. This did not leak.

Removed water from my gas can
I had purchased some gas from a small convenience store and stored it in my gas can. I had put some of the gas in my lawnmower and weedeater and noticed they started running rough like maybe there was some water in the gas. My friend suggested to try some heat and I put it in both and they started running great again. The heat removed the moisture like it's known for. Great product and I have bought additional bottles to have on hand. Great product

Feels like a new truck again.
This stuff works, I ran it through my trucks gas tank with 10 gallons of gas and then used Royal purple Max clean on the following tank and my truck since had been running incredibly smooth st idle and even noticed a small increase in mag. Will definitely be using this product every couple of months to help keep things running smoothly.
