HONDA EU7000I VS YAMAHA EF6300ISED Fuel Efficiency Test | Carburetor vs Injector

In this test I drained both generators completely out of gas then added only 32oz to each tank.
Let's see how long they will run with a 1000 watts load.
HONDA EU7000is
The Honda EU7000iS houses a 389 cc Honda GX390 EFI OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 5500W along with a peak wattage of 7000W. In addition, the device is parallel capable, can be linked to a similar or compatible unit for added power.
With a full tank, the EU7000iS can operate for up to 16 hours (fuel consumption around 0.32 GPH), thanks to its fuel capacity of 5.1 gallons.
YAMAHA 6300ISED
The Yamaha EF6300iSDE's engine, 357 cc Yamaha MZ360 OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 5500W and reaches a peak wattage of 6300W.
The fuel capacity of 4.5 gallons allows the EF6300iSDE to operate for up to 13.3 hours with a full tank (fuel consumption around 0.34 GPH).
