Generac GP5500 Review

Fuel Efficiency

The Generac GP5500 portable generator is designed with a straightforward approach to run only on standard gasoline rather than propane. However, there’s no known method to convert GP5500 into a dual-fuel generator, so consumers have to rely on conventional gasoline. 

Although this power-generation machine doesn’t work on propane, the traditional gasoline does provide an easy and cost-effective option. 

With an impressive 7.2 gallon fuel-tank, this Generac gas generator provides an optimal run-time of 10-hours at half load, which is perfect to power several smaller tools and equipment or if you’ve got a very particular, precise task.  

Generac GP5500 Noise Level

Though portable generators are known to create a bit of noise due to their motorized parts, you’ll not be able to detect the sound of this portable generator.   

This gas powered generator includes a sheathed motor using the hardened steel framing. Although it gives the unit long-lasting durability but also adds to the sound level generated by the GP5500.   

But you don’t have to worry about that since Generac has countered this ‘portable generators noise level issue’ with this gas-model by using a low-tone muffler, which is designed specifically to lower the noise levels generated during operation. 

In addition to that, the unit has a motor, assisted by engine mounts (also known as motor mounts) at several places to lower the vibrations as possible and keep the operation consistent and smooth. 

All these features have played a part to decrease the noise level of this portable gas generator and paved the way for it to run successfully and quietly at about 71 decibels, which is slightly more than the normal conversation.
