How much gas does the Honda EU1000i use?

  • At 1/4 load: 0.55 gal ÷ 6.8 h ≈ 0.08 gallons per hour
  • At rated load: 0.55 gal ÷ 3.0 h ≈ 0.18 gallons per hour

These are our calculations from Honda's published tank size and runtimes, not Honda figures.

Manufacturer figures vs. our estimates

Only the runtimes listed above are Honda's own published figures. When your load and fuel amount exactly match one of them, the calculator labels the result Manufacturer Published Runtime. Loads between published figures are labeled Estimated from Manufacturer Data, and loads outside the published range are labeled Extrapolated with a wider range. Those are GeneratorRuntime estimates, not Honda specifications.

Operate it safely

Like every portable generator, the Honda EU1000i must be operated according to the manufacturer's safety instructions: outdoors only, well away from doors, windows, and vents, with battery CO alarms inside your home. A CO shutoff feature is not a substitute for safe placement. Never refuel while the engine is running or hot.
