Rated 4 out of 5 by good buy for the price Good overall generator. A little on the loud side compared to other generators of the same size. Powers my camper with no problems once I got the 30 amp 4 prong adapter. My only complaint is with the pull start assembly. Already needs replaced. The plastic center spring housing has broken. It was not abused or treated roughly. Pull start hung up one time, took apart to see what the problem was and discovered black plastic pieces broken and falling out of pull start assembly. Once I replace that I'll be a happy camper again. July 8, 2014
Rated 5 out of 5 by This product works well for the price This product was easy to use right out of the box. It was easy to set up. Started the first time. I have not had to run it for long time yet but now I am ready for a power outage. July 4, 2014
Rated 5 out of 5 by Everything it was advertised to be. Loving my Generac GP5500. Powerful enough to run the essentials of my home when I need it to. Portable enough to use it for other things around the house or to haul in the back of my truck to work for me on the road away from home. July 4, 2014
Rated 4 out of 5 by Decent value for the price Bought the 5500 to keep the fridge, freezer and sump pump going after the latest storm knocked out power in two counties. Assembled it by flashlight in the garage and got it up and running with only one problem ... the spark plug boot was broken. After a quick wrap with electrical tape, we were in business. Started it up at 10:30 at night and stopped it to refuel at 8:30 the next morning. Power came back on about an hour after that. All in all, I think it was a good investment. Just need to follow up on replacing the boot and the recommended maintenance schedule. July 3, 2014
Rated 5 out of 5 by Great American made unit After a strong storm took out our power, and we had estimates of 3-days to restore it from the electric company, I decided to buy a generator. I loved the Generac unit because it is made in the USA, is well priced and has a number of models available. Hooked it up and I had emergency power! July 2, 2014
Rated 5 out of 5 by This product has everything we needed I'm very satisfied with this generator. It will handle everything we need it to. My husband is on oxygen at night, so he needed something that will keep it running. June 22, 2014
Rated 5 out of 5 by Saved the day When my generator failed to start in a heck of a storm, I called my son to have him help. He purchased the 5500 portable unit & after hastily unpacking had it started in 3 pulls. It saved the flooding basement & powered some lights for us until power was restored. I am now having our electrician install the house transfer switch and can rely on our 5500 if needed again. June 19, 2014
Rated 5 out of 5 by great value for the price Just bought the generator and put it together very quick....less than a half hour. Very easy to start. We haven't had the opportunity to use it for any length of time just long ennough to make sure it worked June 8, 2014

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?

Answer: 
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.

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.

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.
