## Description

Benefits of the REV-X Super Tester Ethanol Test Kit:The Ethanol Testing Kit by Rev-X is simply the smartest & easiest tool available to verify the percentage of damaging Ethanol Alcohol added to Gasoline. Over 95% of the Gasoline sold to the general public contains 10% or more Ethanol Alcohol. Most Vehicles that are Flex Fuel Compliant were designed to avoid the harmful side effects of Ethanol Alcohol at levels of 10% or less. The only way to truly protect your investment is to know if Ethanol Alcohol is present in the Gasoline you are purchasing and if so, at what percentage. The REV-X Super Tester Ethanol Testing Kit is loaded with features. ‣ Extremely Simple To Use. ‣ Full Size Bottle that is Easy To Hold. ‣ Bold Easy To Read Increments. ‣ Displays Percentage Of Alcohol/Water Concentration. ‣ For Use With All Gasoline. ‣ Also Tests Pure or Straight Alcohols for Moisture Content. ‣ Test Bottle Impervious To Alcohols and Gasoline. ‣ Can Be Reused On New Samples For Years. ‣ Mandatory For Marine Gasoline. ‣ Economical Tool. Instructions For Using The REV-X Super Tester Ethanol Test Kit: 1. Fill with water to the "Water Fill Line". 2. Fill with the Gasoline or Alcohol to the top edge of the bottle. 3. Reapply Cap and Firmly tighten - To avoid any leaking liquid. 4. Shake until contents are fully blended (or suspended). 5. Rest on a flat surface and let the contents (Gasoline, Alcohol and Water) settle out of suspension. 6. Any Alcohol/Water present will appear above the "Water Fill Line" and under the Gasoline that is present above it. 7. The volume present above the "Water Fill Line" will represent the total percentage of Alcohol/Water present in the Gasoline or Alcohol that was tested. 8. When test is complete simply pour out contents & allow air dry. When dry, reapply cap and the tester is ready to be used again.

Review: Cheap plastic, even cheaper sticker and unusable due to product sticker over graduations - Thanks to desertcart I got my money back otherwise it would have been £25 down the drain. Some Einstein at their warehouse decided to put an adhesive product sticker right over the read off label which itself is a VERY poorly adhered sticker onto what is a VERY poor quality plastic bottle. Seriously You are better off just getting a 100ml glass measuring cylinder, the type used in school chemistry labs, and using one of those. I reported this to the seller and whilst they apologised there was no offer of a replacement or refund so once again thanks desertcart.

## Questions & Answers

**Q: is this one time use? do I need to add other things other then fuel and water before the test?**
A: You can use it many times. 
It’s really easy to use 
Just add water to the water line mark the fuel on top of it. 
Shake for about 10 seconds and then let stand for about 10 seconds. You will have your result.
Nothing else needed for this test.

**Q: How can a plastic bottle with just simple graduations cost so much?  It cannot cost more than $0.35 a piece to make this thing.**
A: The graduations are written on tape and then stuck on the bottle. I can see a price tag of maybe $3.95 not $14.95 like I paid.  But it does work.

**Q: does this test diesel fuel?**
A: No, it tests for alcohol percent in gasoline.

**Q: What if the gasoline your testing has sta-bil 22264 360 protection in it? will this still work?**
A: I honestly can't say but I would think so. Google your best bet for a question like this
