Know the Ethanol Content of Your Fuel Before It Goes in Your Tank
As performance enthusiasts, we do not like guessing when it comes to fuel quality. Ethanol content can vary significantly from pump to pump, and that variation matters when you are tuning, blending fuel, or trying to maintain consistent performance.
Most basic ethanol testers get the job done, but they often leave room for frustration. Some are difficult to read, some do not provide a full-scale measurement range, and some use graphics that can fade, smear, or come off after repeated fuel exposure.
That is why we developed the Fuel-It! Glass Ethanol Content Tester. It was designed specifically for enthusiasts who want a simple, accurate, reusable way to check ethanol content before the fuel goes into the vehicle.
Whether you are checking straight pump fuel, confirming your E85 quality, or dialing in a custom ethanol blend, the Fuel-It! Ethanol Content Tester gives you a fast, reliable way to know exactly what you are running.
Test in just 3 easy steps
Step 1: Add water

The clear glass vial, freestanding flat-bottom design, easy-to-read scale, and 2.5% measurement increments make it easy to verify everything from pump gas to E85 blends without guessing.
