Runs 8.1 hours on a single 0.95-gallon tank of gas. HONDA GENERATOR EU 2000 INVERTER. It runs strong and well. It got a new oil change, always run 100% ethanol free blue gas. IT RUNS FOR MANY HOURS WITH ONE TANK. I used to run the furnace and electric devices from my camper, also the 11,000 BTU rooftop air conditioner in my camper, and on an emergency basis to run my home freezer, etc., when the power goes out for days at a time. You are welcome to check it out for yourself.

There is a video of it running.
