Unit now showing 25 hrs. Bought after storm took out the electrical service drop. Put together and had up and running in less than an hour. Operation is straight forward and pretty much plug and play so to speak. Only thing I noticed was the powder coating on the frame seemed very thin in places. could have been a little thicker. This is not a game changer just something I noticed. When you add the oil the first time try to have a long neck funnel, it's a whole lot easier to hit the opening to add the oil. Look forward to many years usage from this unit.

[This review was collected as part of a promotion.] Has already been a life-saver this fall. Lost power briefly within two weeks receiving it. I don't have a washer or dryer, so can't comment on how it would handle an entire load of heavy appliances, but it covered everything else. I lose power a few times a year and work from home, so this is pretty essential for me! It is very heavy, so I did need help moving it and getting it out of the box to set up, but after that everything was simple.

I love the generator. It works excellent, just as expected. Starts immediately and runs well; provides the power I need when required. The only complaint I have is the noise level when running. Surely Generac could or should have equipped the generator with a muffler system to quieten the sound emitted.

After 3 years of ownership with w1 hr/year running, had to run generator for 4 days continuously with time-outs for refueling and oil-checking. Clean gas, fresh oil 2 days prior to weather event and when needed, the generator started immediately, took the load with no surging. Minor light flickering of LED lights when dimmed, but voltage was spot-on and consistent. Heavy motor starting loads did not change generator output or tone and fuel useage to run 4 bedroom house with well, furnace, lighting, entertainment, refrigerator, dish-washer and on occasion electric oven was about 5 gallons per 24 hour day. Generator is well designed and apparently bullet proof.

I just bought a GP8000E, so I'm just getting familiar with it. I did buy it through a support company that will be maintaining it for me. So far, my one suggestion would be to clearly mark the gas on/off switch. It's not clearly marked on the machine. The company did add a green marker for "on," but none for "off." The sticker you have on it does not help at all. I had to call my support company to find out that when the switch is set to noon and 6, the gas is on, and when set to 9 and 3, the gas is off. The manual does not illustrate this very well, either.

I purchased my GP6500 primarily to run power tools. I have a large lot which makes it impractical to use an extension cord. I opened the box and followed the instructions on assembly which was easy (putting oil in the machine, wheels on etc.). I put gas in it and it started flawlessly. I have run a 15 amp table saw and shop vac simultaneously with no problem. In addition, I plugged in a power washer and ran it for hours without an incident. When you start it and hear it run you can tell it is a quality machine. It has a lot of power and runs very smooth. I even use it when I have access to power because I like it so much.

Got this as 'insurance' against the increasing number of power outages. My electrician set up wiring for easy connection to my breaker box. It's really easy to roll around and use. It runs all the essential things (sump pump, furnace, refrigerator/freezer some lights, one burner on fridge, computer) - about 1/2 the house - plenty for an extended outage. I am almost looking forward to putting it through its paces during the next outage. Almost.

I bought this unit to replace a larger generator two years ago. It went through on hurricane like a champ. One half of my home was easily powered (which was more than enough, 1 AC 3 yard pumps, misc. 20 A breakers). The unit stores easily when not in use and is easy to move to hook up the transfer switch. I recently had a bad battery and the folks at Generac are replacing it. What a pleasant surprise and a guarantee that I will buy another Generac when the time comes.

The.instructions for assembly were easy to follow. The instructions were straight forward with all parts included. The generator started on the second pull and worked flawlessly. I feel confident the generator will help keep my family comfortable during an extended power outrage. Having the generator and being able to connect it to the house is very convenient.

Bought this as an emergency purchase. Had borrowed a no name generator for camping to have it quit working. Went to Menards in Princeton Indiana at closing time and found this model. Had been wanting of my own for various reasons over the years and have always put it off because of so many choices out there. Being forced to make a split decision in bio this one was a blessing in disguise. Could not be happier with this generator.
