Rated 5 out of 5 by 5500 Portable Generator Excellent reliable power generator - the only brand we use. Would like to purchase the power washer to clean home siding & wooden fence. August 15, 2015
Rated 4 out of 5 by great features purchased product but haven't had a need for it yet. But impressed with most reviews I've seen . August 13, 2015
Rated 5 out of 5 by Love It Purchased this 8/2/15. This is very easy to assemble. All there is to assemble is the wheels. handle. and feet. Add oil and fuel and it fired up on the second pull. Havent needed to use this yet but my plan when needed is to run fridge, lamps. fan, internet modem and tv. No doubt in my mind that this unit will handle that plus much more. Have a kerosene heater for heat in the winter so not running the furnace isnt a problem. For cooking we will use a 2 burner hot plate. Fiist time I fired it up I plugged in 3 hair dryers on high heat and generator never missed a beat or bogged down. Will start and run once a month for half hour and keep up on maintenance and Im sure I will get years of sevice from this. August 10, 2015
Rated 4 out of 5 by Great product for your house. I originally bought thus generator to run our house incase of a power outage, we had a storm go through our area and lost power for about 24 hours. I purchase the generator to run my sub pump, fridge and freezer. It had no problem running them all. I did purchase a heavy duty 240v/30 amp which I would recommend. The fuel tank last about 10 to 16 hours depending on the load. August 5, 2015
Rated 4 out of 5 by The product works good This generator starts hard in the morning . After it is started works real good . It goes a long time on a tank of gas. August 5, 2015
Rated 4 out of 5 by Powers the necessities Had an outage for 3 days this summer. I was able to run two refrigerators, lights and a sump pump without any issues. August 4, 2015
Rated 5 out of 5 by Good value Got this to replace smaller GP 3250, needed more power due to outages getting longer. Also 30A 110/220V connector allows connection to load centrr (breaker box) via disconnect switch. No more extension cords.Wanted the LP 5500, but Generac does not allow that to be connected to a large propane tank, only 20 & 30 lb. bottles. Claims it will void the warrany, propane is propane??GP 5500 is excellent and reccomend it. July 27, 2015
Rated 4 out of 5 by This generator was easy to assemble, even during a power outage. I had to assemble my unit during a power outage and it went together easily. It seems to be well built and very sturdy. I bought a generac because it had a good reputation, the price is a little high but I expect to have trouble free usage for years to come. July 20, 2015

1 Person needs an answerI have this question too

Answers

Answer: 
The GP Series portable generators are shipped from factory with SAE 30 non-synthetic oil. When choosing oil to utilize for a generator, the chart located in the Maintenance Section of your unit’s owner’s manual should be viewed as to what the coldest temperature will be experienced. The oil utilized for a cold temperature will be acceptable for use at warmer temperatures, but oil designated for warmer temperatures are not acceptable for use in colder temperatures. This is why a synthetic 5W-30 is the recommended oil for places with significant temperature changes, as it covers all temperature ranges. The appropriate intervals for oil changes and other maintenance items will be located in the owner’s manual in the Maintenance section as well.

Answer: 
Generac does not offer an electric start kit for that model, if you step it up to the 7500 watt model it will come with an electric start option. The smallest one that we offer with an electric start will be Grainger item # 6FDL0.

The tank was filled to the top past the line. Experiencing shutdown after running for about ten minutes.

Choke ok, motor ok, silver start switch facing in upright position also. Does filling the tank past the fuel line have anything to do with it.

We tested it yesterday with less than half a tank and it ran beautifully.

Does the generator need to be out of the rain?

This generator was designed to work at peak performance with regular unleaded gas. The fuel level in the gas tank should have no impact on performance until the tank is empty.
