After returning the original purchase due to a defect, the replacement generator went together quickly and easily. I was concerned about previous reviews that talked about difficulty putting oil in and putting the wheels on, but I had no problems. You do need a funnel to add oil, but a funnel with a long neck worked fine. After the unit was assembled, I put some fuel in it and it fired right up. I also put a small load on it to ensure it was actually working. All in all, I'm happy and confident this unit will perform as expected when it is needed.

I just picked up this generator under the strong recommendation from an electrician. Fantastic advice. As mentioned above it is easy to use and laid out quite simple. I find it to be built solid and durable. I love the electric start feature as well as the pull start in the event the battery is too weak to crank the engine. Battery came charged when I received it and even though we had temps at -20 to -30 all month she still fired up quite easily. Highly recommend this generator.

We have lived in PA for year and half and have lost power twice for a week each time. We have done our research, and we are so pleased with the GENERAC 7500. Delivery was quick and easy, putting it together out of the box was quick and easy. Our electrician is installing an interlock into the circuit breaker box, so we will be trained and ready for the next "this never happens" storm that knocks out power. We are on a well, and have a sump pump. Having this generator gives us such relief in knowing we can still operate most of our home off the grid temporarily. Also, how cool that if we need to take it on a camping trip, we can load it into the truck and go! Awesome idea!

I have owned this generator approximately five years, it only has 60 hrs on it. It has been in auth shop twice and has had four new fuel pumps. Also new voltage regulator It has now blown the fuse behind the control panel and blows another as soon as installed?? I seldom post negative comments on products. In fact this is my first!!!! Very disappointed!!!

This new unit is replacing a 9 KW portable unit that ran my whole house except for the Hot Tub and central AC. The new Generac runs the whole house with power left over. I just wish that it would come with a voltmeter. It was easy to assemble and runs great.

I bought this in the fall of 2012 after Katrina ripped through the Northeast. Our area was ten days without power being restored. We suffered through three days without power before getting this. Our home water supply comes from a well. No power, no water. Or heat, or showers, or communications. This unit has enough power to run the well, satellite, refrigerators, freezers, lights, coffee pot, microwave, televisions, and the list goes on. I just pulled it outside and started it up again for the second time this year. It powered up on the second pull and was running strong. I never worry about losing power now. Get the biggest one you can afford, but the 6500 will get you through any power outage with minimal disruption to your life. No regrets on this purchase. Quality machine.

strong runner, love that it runs diesel. fuel tank is large enough to keep it running for a VERY long time, especially at lighter loads. my only gripe is the pullstart. i would be willing to bet that Paul Bunyan himself would not be able to pull start this generator. Make sure the battery is charged.

I've owned my 7500E for just over 8 months now. As others have mentioned, from ordering to delivery was flawless, set up took very little time. Once I had the transfer switch installed, I ran through a test of all 10 circuits with the electrician and it barely created a load on it...even he was amazed. I'm extremely pleased with my purchase and feel very confident recommending it to anyone considering this model.

Purchased the gp6500 after a lot of research. It offered the best power for the price. We only had to use it for a little over 1 hour for the first 7 months we owned it. We have been faithful in starting it about every other week or so and ran it with a load for about 20 minutes. We have kept the tank full of gas treated with stabilizer. Well sure enough we lost power this week do to freak March snowstorm. Started on the second pull. It ran over the course of three days for 29 hours. Worked flawlessly. Really a lifesaver, especially with three kids and the wife. Ran 3/4 of the entire house including a well pump, two refrigerators and a deep freezer. We have a Woodstove in the basement so no need for it to run a heat source. Bottom line... Awesome product, great value and so far seems durable. If you're debating this generator, go for it!!!!

We were in the Michigan Ice Storm of December 22, 2013. Our yard looked like a war zone when it was over, trees pulled our power lines to the ground. I bought this generator on Monday the 23rd and got it running and hooked up to my fridge, freezer and furnace and several lights in no time at all, very easy to set up and run. It ran flawlessly for four whole days and nights, it would run 12-14 hours on a tank of gas. So glad I bought this, we enjoyed our Christmas with family, even though we did not have power to our house. Buy this generator, it will run your whole house!
