what type of oil is recomended

Asked by: digg
I live in the Midwest where our temps vary greatly. If you live in the same climate, just go to the auto parts store and get synthetic 5w30 and you'll be covered.

5,500-Watt Gasoline Powered Portable Generator is rated 4.7 out of 5 by 807.
Rated 5 out of 5 by from Purchased this generator 4 years ago. It currently has 60 hours of use. I power 6 breakers in m... Purchased this generator 4 years ago. It currently has 60 hours of use. I power 6 breakers in my house through a Reliance manual transfer switch. These breakers power 2 full size refrigerator freezers, all outlets in the kitchen, three bedrooms and family room. We can easily use the 1200 watt microwave and a toaster oven. We power three computer systems, gaming systems, three televisions, we maintain WiFi, internet and telephone. I added a Tri-fuel kit to this generator and it operates perfectly on gasoline, propane or natural gas. At approximately 50% load, a full tank of gasoline lasts 11-12 hours, 40 lb (5 gal) tank of propane lasts 8 hours, and connected to the house natural gas unlimited run time. It is easy to start and service. Always starts first or second pull.

Rated 5 out of 5 by from Generac 5500 During the Hurricane Maria, we used our GP5500 to run 2 refrigerators a few lights, TV and cable box without any problem. It is an excellent generator and gave us the opportunity to continue our daily work as usual. I recommend it because of the company reputation and services. Easy to install and use.

Rated 5 out of 5 by from Great experience with my first generator. My first generator, procrastinated for years an never got around to purchasing until hurricane Maria, my son convinced me to buy Generac, he has one in another state, read numerous reviews online, found it to be simplistic an everything it says it will do. My family was spared the inconvenience of doing without electricity for four days. I saved hundreds of dollars of food in my freezer an refrigerator. I wished I had purchased one years ago. I live on Wilmington Island Ga.. My neighbors who did not have a gererator are asking numerous questions which are answered in the manual an online on the website. I whole heartily endorse this product.

Rated 5 out of 5 by from Ez to use We were fortunate enough to have a friend let us borrow this generator during hurricane Irma. We lost power on Monday at 1 AM and at 4 PM we started the generator and were able to save our food in our fridge and deep freezer. It is Friday afternoon and we still have no power but this generator allowed us to run two fans,a lamo, charge our cell phones and my daughters electronic games,microwave and alternating with toaster oven as to not overload system. I was able to stop and start and fill generator up with gas while my husband was away at work We will definitely purchase this generator for future hurricane power outages as it is a lifesaver!!!

Rated 4 out of 5 by from Good value, would buy again Great product. Would buy again if I needed to. Purchased for Hurricane Irma. Easy assembly overall and started on first pull. Only criticisms are (1) did not come w/ any kind of cord, which was rough considering the buying frenzy before the hurricane, and (2) one of the nuts that holds the handle to move the generator from point A to point B became loose and actually fell off in the grass. I believe it became loose from the vibration of the generator for the day or two that it was running while power was out. Fortunately, we found the nut that fell into the grass; otherwise, I'd be more upset about the product. Overall, great product. We will see how it holds up over time.

I am ordering a second one this week

Rated 5 out of 5 by from Excellent generator I've had this generator for over a year. I bought it when we lost power for a week during Hurricane Hermine. I it ran flawlessly for that week. Now we've been without power for 3 days and counting following Hurricane Irma. Always starts on the first pull, and has plenty of power. I back feed my panel, and by being selective of what breakers are on, I can run everything in my home short of the HVAC. This morning I was able to run our electric water heater that has 4500 watt elements, 5 fans a few lights, the TV wifi and surround sound system simultaneously. Once the water was hot, switch that breaker off and turn refrigerator and freezer back on. Burns about a half gallon an hour in gas. We'll worth the money!
