How to Use the Calculator

What's in Your Tank?

1. Tank Size: Enter the total capacity of your fuel tank in gallons. Use the preset buttons for common models or enter it manually.

2. Current Fuel Level: Use the interactive fuel gauge, the +/− buttons, or the presets (E, ¼, ½, ¾, F) to set your current fuel level.

3. Current Ethanol %: Enter the ethanol percentage of the fuel currently in your tank. For most 91/93 octane pump gas, this is 10%. For ethanol-free gas, enter 0.

What's Your Desired Blend?

1. Target Ethanol %: Enter your desired final ethanol percentage (e.g., 30 for E30, 60 for E60).

2. E85 Pump's Actual Ethanol %: E85 can vary. Test your fuel and enter the actual percentage here (e.g., 76 for 76% ethanol).
