I have not started the generator yet but in getting it ready I've identified a few disappointing aspects. First and probably the biggest disappointment is the requirement to measure valve clearance at every 50 hour interval. The owners manual informs you this is pretty complicated (without describing the procedure) and suggests you have a qualified dealer do it (...did I mention the requirement for every 50 hours of operation?). The generator came with a note indicating the unit is "shipped without oil" and they supply 2 quarts for the required 1.7 quart capacity. When I poured the first quart in, the oil level was well above full on the dipstick ….indicating the engine was not even close to empty of oil. I also found the assembly instructions to be near non-existent because the exploded view of the assembly was so small in the users manual; also - it did not reference torques for any bolts or wear lock washers vs. nylon nuts should be used. I also noted two wires stretched very tight across the oil filter - which needed to be disconnected and re-connected following a less stressful path. I truly hope the generator will work well despite these initial findings.

There is no voltmeter on the generator to indicate the generator is running at the correct speed to make the rated voltages. The generator is way too loud! It is so loud two people can't understand a word being said if you are very close to it. Muffler seems to be too small for the noise produced. The 50 amp receptacle is on the bottom of the control box. This is a bad place to be because the male plug for it tries to vibrate out. The little wire thingy that is supposed to hold the plug in is a joke because it doesn't fit any plugs I've seen. It needs a re-design.

[This review was collected as part of a promotion.] This generator is a beast! The craftmanship is great, and it's a whopping 220+ lbs. Perfect for generating an entire house with no difficulty. Excellent quality and packed with care. I'd recommend it to anyone who could use it. It is worth every penny!

I have not had a chance to run this generator for an extended period of time yet, but I know that it is easy to start and has sufficient power rating to run a refrigerator, freezer, television, a microwave, and two electric heaters, and a few lights during a power outage. Easy to roll it into service and place into service.

Compared several modals, sizes, features, the generac was the best overall. Very reliable, easy to use. Had power through hurricane for refrigerator, window a/c , most house lights, made a 4 day power outage tolerable. Had a 12 hour outage recently, I had just come home from a triple bypass, instructed my wife how to start and she got power to house in matter of minutes. Would not want to be without it.

Good value for the money. Will take stress away from power outages. Protect my home from water freezing in pipes and damages thereafter during winter months. Comfort for family during outages. Can't rely on Power Company to get power back in reasonable timeframe, less than one day. Have had outages lasting 1 - 3 days. Power Company continues to get worse every year due to their lack of maintenance, outage prevention, manpower reduction.

I just purchased the GP7500E for emergency backup for our house. We experience several power outages during the winter. This is my first purchase of a portable generator. It was easy to assemble. I added oil and gas, turned on the fuel, set the choke, pushed the start button and it started right away. It even comes with a battery charger. This will be the perfect back up power for us. It is a little louder than I had hoped but, we can get over that when the first outage happens and we have power in the house. It is connected to a manual transfer panel and the change from hydro to back up is very easy to accomplish. Come on winter storms!!

This is a great product for the price.The generator starts easily and runs fairly quiet.The fuel tank is huge and i can get about 8 hours out of a tank.I gave it 4 stars for only one reason and that is because of the wheels.This generator is very heavy and they should have sealed bearings on the wheels because when you have to move it on grass it is hard to push or pull.

A portable yet powerful generator that is well suited for home backup power needs. Wheels and collapsable handle make it easy to manuver. Electric start makes it a snap to fire up. Enough output to protect freezers and fridgerators. 240VAC has enough output to power a well pump.

The GP8000E Generac Portable Generator is the first generator we have acquired. Its no nonsense starting instructions make it easy to start the generator. We read through the instructions completely and started it same day we purchased to validate reliability and our know-how and it started immediately and safely. Instructions are easy to understand and follow. We look forward to having it up and ready to go whenever we may need it. Safety directions are clear and thorough.
