Rated 4.8 out of 5 by 425reviewers.
Rated 5 out of 5 by Solidly Build I bought this generator during a winter ice storm. I didn't have any options to choose from as it was the last generator they had at the store. As soon as I opened the box I could tell it was put together very well. I got it set up and it started on the first pull. It does the job very well and has some extra features that are very nice. Even though I didn't have any other choices, I am glad I bought the Generac as it seems to be one of the best available. February 18, 2015
Rated 4 out of 5 by Great features Really nice unit that will come though in an emergency February 4, 2015
Rated 5 out of 5 by Good value for the money Took it out of the box, assembled it as directed. No issues. Filled with the oil provided, used the whole quart. Manual does not state how much oil but the entire quart is what it took. Put some gas in it, a little sea foam, set it to start and pulled the starter rope. Started on the first easy pull! I let it run about 5 minutes. It's about as loud as a riding mower. Plugged a shop vac into it and it works just fine. Shut it off with no issues. January 31, 2015
Rated 5 out of 5 by purchased wired and ready , let it show and the power off and were ready. All gassed up and ran a test run and ready to use. Ready for the snow and the power to go off. January 31, 2015
Rated 5 out of 5 by More power to you This gp5500 is an awesome machine. It got us through sandy with no problem. Ran like a champ. Starts right up on first pull. It's a beast. The only setback is this beast is loud. Very loud. January 31, 2015
Rated 4 out of 5 by Consumer friendly The unit is easy to start, powerful, and affordable. Staff assembled and ran the unit prior to pick up. Powered my needed electrical appliances and comfort items. Glad to have this unit. January 30, 2015

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?

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.
