This is the first generator I own, so I am not very experienced. But I would think that it should run longer than 3 hrs on a tank fill up.

unit looks and sounds good .one of those buys you hope you dont have to use but hope if power fails will take care of our needs

This is the best generator you can buy when things go bad. I love this generator, it powered everything I need with out a problem.

When your power goes out it tends to be a pain in the backside. This generator worked great for 15 hours with no problem at all. Very Happy !!

I recently purchased my Generac GP8000E generator and it was a cinch to assemble and hook up at my new home.

use it on jobsites without power,runs 1/2" drill just fine and at home when utilities fail. all around good machine.

I have owned a Generac for about 23 years. It is a very dependable product and I would not buy any brand.

Used for back-up emergency power works great runs well pump and everything else needed to keep our house going.

i bought this product to keep worm in winter storms and keep thing running if summer power failure happens I expect this to be great

This generator is great and starts right up with no problem. The option to be able to pull start it is also great.
