Ethanol Fuel Calculator
Calculate the cost and performance impacts of ethanol fuel blends with our comprehensive calculator. Determine fuel economy, cost savings, and compare different ethanol blends.
Step 1: Vehicle Specifications
Understanding Ethanol Blends
Most vehicles can use E10 (10% ethanol) without modification. E15 is approved for 2001 and newer vehicles. E85 (85% ethanol) requires a flex-fuel vehicle.
Step 2: Fuel Parameters
About Ethanol Fuel Economy
Ethanol contains less energy per gallon than gasoline, typically resulting in a 3-5% fuel economy reduction with E10 and up to 25-30% with E85. The exact impact varies by vehicle.

Fuel Cost Breakdown
Ethanol Blend Formula
Blend Price = (Gasoline% × Gasoline Price) + (Ethanol% × Ethanol Price)
To calculate blend price: Multiply the percentage of gasoline by its price, add the percentage of ethanol multiplied by its price.
