Skepticle about the fuel your buying? Want to know if you have water in your fuel? Is your gas truly Ethenol free? Then you need this simple tester. Inexpensive and good insurance before you ruin a vintage engine.

Works great, super easy to use

I recommend these testers because they have a lid opening big enough to pour the gas into the bottle with less spillage. The labels are well-marked. They should work easily. I don't quite know what to do with the gas once the water is mixed with it in terms of disposal. I believe they will work well, but it's the problem with the disposal of the gas that gets mixed with the water to test for ethanol that troubles me not using them so far.

Pretty simple device, works great, see how much ethanol is in your gas. It's almost always going to be close to 10% for ordinary gas.

Made of plastic so it won't shatter like my glass one did

Why did you pick this product vs others?:You get 2 bottles instead of one, and it’s perfect for what it’s needed for.Build quality:BOTH containers melted before I had a chance to use them. They are not sturdy. They melted from just being in the car, from NYC heat, which is unacceptable.

WORKS GREAT AS ADVERTISED

Must have if your hotrod runs on e85. Very simple to use and you always know exactly what your ethanol content is.
