Gen replacement

The first one had a bad LP regulator. Home Depot was great at getting it swapped. The replacement ran like a champ.

Stripped oil dipstick

Brand new, unscrewed the oil dipstick to add oil, and found out the threads were stripped. Immediately ordered and had to pay for a new one.

Power on demand!

I am extremely satisfied with my purchase of the GP9500 Tri Fuel Generator. This purchase will insure emergency power when the need presents itself.

Bad warranty

We had an outlet burn out and the warranty would not replace. We also had to search several places to even take it too. Not an easy process

Excellent Generator-Generac GP6500

Bought this Generator used with 100 hours in it (4 days of use) got a great price and looks and works like new! I can run everything in house, all lights, electric stove (not oven), heat (furnace) & hot water heater. Haven't tried to run the central air unit yet but the heat and hot water is more important, anyway I ran everything with no hesitation or strain on generator. I gave it a 4 on features because I wish it had a voltage meter on it otherwise all 5's! Full tank of gas you should get 8+hours run time with everything I described above, I Love this Generator and now ready for any outage, may not need for 3 years but will be ready when it happens.

Love the first 8000 but the second generator let me down.

170 hours on generator -two months old Stopped producing power. Not happy. Power would come back when I jumped the field with a drill - spinning it backwards. Brought to a dealer rep - we will see what they find. Hoping it will be under warranty without a battle. Walpole,MA

This generator was a God send

My house caught fire and was unlivable. But we had 2 freezers with LOTS of food in them. I bought this model generator, at a reasonable price, to keep my freezers running until I could get my house livable again. It’s the perfect size and wattage for me, affordable and it runs for ever on a tank of gas. Thank you Generac!!

Steady, Reliable, Ready

At 68 years old it was just getting too much for the wife and me to pull-start that old 5k "Powerbase" predecessor anymore, particularly on a cold, snowy day. We moved into a new(er) house this Summer, and decided to upgrade the generator as well. After a ton of research, I settled on the Generac GP8000e, and I have not been disappointed. Last week the power was down Tue, Wed, Thur, and Friday due to a nasty storm. The GP8000e ran day & night for four days without missing a beat. On Saturday, with power retored, we agreed that that beauty had definitely paid for itself. ( We have 2 freezers, the fridge, and it ran our deep well pump as well, so we had water for showers & flushing, besides all our lights and TV. We were very comfortable throughout the storm, and my wife was able to refuel & restart the gen by herself in my absence, ( something she could have never done with the old 5,000. Then,just as we were patting ourselves on the back for the wisdom of our purchase, last night (Sunday) the power went out again, with "Estimate for Restoration: Unknown." To be perfectly honest, we don't care! We started the GP8000e and went to bed. ( It's just Not our Problem! ) I would like to add that: We checked the oil at every "Refuel" and it never used a drop. Actual "Runtime" unknown, we refueled every 12 hours. I definitely Recommend this unit for all of you. ( I made my son buy one for his house ) This is not a purchase, this is an "investment".

This a great generator and it is priced right.

I use my generator to power my house when the electricity goes out. It is sized just right for what I need. It is easy to start and set up. With the fold down handle attached it makes it very easy to maneuver the unit wherever you need it or to store it away. I have researched and used a lot of other generators and this is the best so far. I am very happy with this unit and I am sure it will bring me years of service.
