Love this generator

I bought this generator 3 years ago and have lost power 4 times, once for 3 days and it has never let us down. The battery died after the second year and I never replaced it as it always starts with one pull. I always treat my fuel with stabil then shut the fuel valve off with the engine running letting it run until it dies, this assures emptying out the carburetor reducing gumming up issues from hanging around. I run Pennzoil 10w30 motor oil and change it anually. What I really like is the engine adjusts for load so it isn't screaming when there is no load.

Great backup for home office.

I purchased as a backup to provide power to deep freezer, refrigerator, and home office computers. It was easy to connect and provides ample power for my needs. I looked at various generator manufacturers for some time. I decided on Generac because it had the features I needed; was available thru my local service station and could be delivered to my home in time to save my refrigerated food from defrosting. I only need it for 26 hours before utility power was restored. I changed the oil so I am ready for next outage. I estimated that saving the stored food paid for half of the cost of the Generator. Not missing the days work paid for the other half.

Excellent Quality!!

[This review was collected as part of a promotion.] I received this Generac GP6500 portable generatoras a free sample. I think the quality is excellent. I tried it out right away to see how it performed. It started on the first pull and was able to power all the essentials in my home. I am very pleased with the performance and quality of this generator thus far. I would definitely recommend this product to anyone.

Nice and Quite

Had to replace my old generator (That was not a generac) that had for the last 15 years. Bought this from a local vendor. The unit started right up. I already have a generac home standby but It really uses the propane to run all night. I use this to just run fridge and furnace at night. The home standby was the best purchase ever. Soon as the power goes out the standby will start right up. I have the 6500 run just a few circuits when don't want the standby running. The 6500 has electric start which is nice. I was without power when 1st bought and it ran for 16 hours straight. No problems. I would recommend the generac name to anyone. After bought my home standby my inlaws bought one and love it. Highly recommend the portable 6500E.

power plant of a generator.

This is a great generator for our entire house. No shortage of power and seems to be built solid. I really like the fact that it came with a battery charger to ensure its always ready to go. It's a little loud but not outrageous. Great generator dollar for dollar. We are ready for another ice storm with this Generac.

This generator is really nice and powerfull.

Live in northern Florida, city of Ocala out in horse country and our power grid goes down at least once a month and we also are affected by hurricanes. This generator will power your whole house if required, starts easy, runs quiet for its size. It's real heavy to move around but manageable, I am using the 30A and 50A outlets in tandem to feed my single home electrical panel because the single 50A only gives you 12KW of usable power.

Dependability

I bought the 7500e generator as a back-up power source for my house and shop. I live in a rural area in Oregon, and we lose power occasionally during the winter time. Generac is the generator of choice for a lot of contractors because it's dependable, that's good enough for me.

Economical for size, dependable,easily portable,& easy to use.

I served in the emergency field for years before retiring. In that time, Generac products, especially the generators were used more often than not. The reliability and dependability and ease of use is what sold me on Generac. Great value for such a work horse.

The gas on/off switch is not well illustrated on machine or in manual

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.

Quality Product

I bought the XT8000 series with EFI but it wasn't on the list to submit a review. The unit was delivered in a timely matter with no damage. It was easy to put together and fired right up after adding fuel and oil. I've only run it a couple times for an hour with a oil change each time just to break it in. It runs great and is quieter than my neighbors that is half the size.I'm sure I'll be completely satisfied when it actually comes time to use it. I would recommend this product.
