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.

Had a bad storm NO power for three days. Opened box easy to assemble , added gas oil ran for three days adding only gas ,worked great.

I highly recommend this model. It was simple to set up and started right up. It really does the job.

I use my GP6500 for home backup and I have an electric jackhammer which I use a lot. lots of sandstone on my property and they don't stand a chance

Added oil and gas , one pull and it started right up . I'm a first time generator buyer and very happy with my purchase. Thank you

I bought this after hurricane hit us to have power at the house. It worked very well and I am glad I bought it.

We have this generator for hurricane Fiona working all week giving him a rest for four hours and it's excellent product

The generator is much more noisy than expected. I'm also concerned about need to periodically adjust the valves.

We purchased this product for home backup. Assembly was minimal and it started on the first pull. Hook up to the house was also easy.

I bought my daughter this generator for hurricane Ian and liked it so much that I replaced my 25 year old generator with one for myself.
