  • Vehicle type
  • Detailed engine information
  • Percent ethanol used
  • ABA test results
  • Description of your test process
Ok:
  • 2003 Prius
  • 1.5L 1NZ-FXE
  • E10 vs E30
  • indeterminate as within the margin of error
  • Test protocol - fill a 1 gallon spare can with straight gas. Run the car until all fuel burned and add spare gallon. Drive directly to station recording the amount of fuel burned. Add ratios of fuel to achieve targeted ethanol ratio. Then drive to a 525 ft., 8% and conduct a maximum acceleration, hill climb while recording engine torque, rpm and fuel burn. Calculate the BSFC. Repeat process with a different ethanol ratio.
