REV XE85 Super Tester - Reusable Gasoline Ethanol Testing Kit

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.

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.

Use this to test the non ethanol gas in my area. Tried it on non ethanol and ethanol gas just to verify what it does.

It's simple and works well. I have no other way to judge/test the accuracy but it seems it's accurate.I had 87 octane "with up to 10% ethanol," and it tested within that tolerance. In another project/test I removed the ethanol (and water from humidity) from some stabilized fuel that was sitting for 2 years in a generator (and wouldn't run) in an attempt to make it usable and ethanol-free and this time it tested to zero ethanol as it should so I put it back in the generator as well as my lawnmower (I had a lot of old fuel I bought and stabilized for that generator) and it's been running great.It's so incredibly simple I feel it can't cost more than $1.00 to make. That said, I feel the price could be a lot lower. It's a small bottle with a cap and a label, nothing more.Good luck!

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.

Easy to use
