REV X E85 Super Tester - Reusable Gasoline Ethanol Testing Kit

Worked exactly like it was intended.

It works. I wanted to make certain the non ethanol fuel I was buying for my small engines was in fact ethanol free. This did the trick!

This is super simple. It works as intended. It’s built ok. The quality is ok but it’s simple. Who cares.

I bought this so I could test the ethanol free gas that I want to use in my small engines. It works good. Now I can trust my gas station for ethanol, free gas. It cost a dollar more than regular gas so I wanted to make sure I wasn’t being cheated and yes, the price is a little expensive for a plastic bottle, but the piece of mind is worth it.

Used this to test my gas for water content. Works as stated - a little pricy for a bottle

I saw this used on the Chickanic YouTube channel and purchased it. It is simple to use, just add water to the indicated level and fill the remainder with the gas being tested, shake vigorously, and let set for several minutes. If the water is above the level it was originally filled to, there was ethanol in in the gas and the new level shows the percentage.This happens because that the ethanol in the gas joins with the water and increases the apparent water level.If you purchase 'ethanol free' gas from a pump that does not have a dedicated hose for that gas, you get whatever was in the hose and pump (up to 1/3 gallon) of non ethanol free gas delivered to your fuel container before the ethanol free gas is delivered.

good

Works exactly as described. It's fast and easy to use and the results are simple to see.Turns out my local Sheetz is around E75!The bottle is pretty small and it tips easy, so be slow when you're adding the fuel.
