what type of oil is recomended

Asked by: Anonymous
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 729.
Rated 4 out of 5 by from Easy to assemble, started first pull. With common sense load shedding I was able to run most of m... Easy to assemble, started first pull. With common sense load shedding I was able to run most of my appliances. Just a few notes: 1) They include oil but it's SAE30 and not 10W-30W. No one could tell me but I suspected (and was right) to buy 10W-30W because they only recommend Straight 30 down to 32F (we lost power and it was very cold) 2) The bolts on the rubber bumpers are secured with standard nuts. they should either be nylock or specify loctite because they vibrate loose. 3) It's important to position the generator on a level surface (or biased with the fuel petcock down) or you'll leave a lot of gas in it when it shuts down.

Rated 5 out of 5 by from Starts First Pull This is a great generator. Started with the first pull. Even my petite wife started it on the first pull. Powered my fridge, freezer, gas furnace, and a powerstip for lights/TV with no problem.

Rated 5 out of 5 by from You've come a long way baby! I selected this model based on an immediate need and availability.My previous experience with Generac was with the RV products and it was not good. This model seems well put together, able to take rough handling and starts easily. The electrical performance was a pleasant surprise. The frequency is stable from 1/4 to full load and I wouldn't hesitate to run any appliance with it. The voltage regulator also appears spot on at running load. I hesitate to rate the quality excellent as it has very few hours over the monthly exercise period but I fell confident that it will get the higher rating at the end of next year.

Rated 4 out of 5 by from Great generator, pull start issue This has been a good generator for several years now. This moring however the recoil start (mostly plastic) broke, turning my generator into a 700 dollar hunk of metal. I was able to remove the pull start, and ultimately use a rope to start it, meanwhile my wife got the kids ready for school as i fought with the recoil. When I called Customer service they were incredibly helpful and they are shipping me a new recoil. I would buy this again, but i think the recoil should be upgraded from the factory, its rather frustrating having a 700 dollar generator rendered useless by a 10 dollar plastic part!!!!

Rated 4 out of 5 by from This product is easy to use. I decided to purchase my Generac after I was without power for four days when Hurricane Matthew hit. Thankfully I have not needed to use it yet, but we do tend to lose power during frequent ice storms. I do start, run and shut down my Generac once a month and am VERY please how easy it is to start with just one hand and it only takes 1-2 pulls on the cord. I'm not looking forward to needing to use my Generac, but I am feeling much more confident about getting through another outage by being able to cook and NOT losing any food in my freezer.

Rated 5 out of 5 by from RAN FLAWLESSLY 24/7 FOR 10 STRAIGHT DAYS AFTER SANDY EASY TO START. PLENTY OF POWER. HAD REFRIGERATOR, FURNACE, TV W/ CABLE BOX AND MODEM, A FEW LAMPS , TWO SUMP PUMPS AND RAN A LINE TO EACH OF MY NEIGHBORS FOR THEIR SUMP PUMPS. IT RAN 24/7 (EXCEPT TO GAS AND DO 2 OIL CHANGES) FOR 10 STRAIGHT DAYS FOLLOWING HURRICANE SANDY. GOT ABOUT 10 HRS ON A FULL TANK. SUMPS PUMPS FILLED EVERY TEN MINUTES SO I COULDN'T EVEN COOL IT DOWN FOR LONG. THIS GENERATOR SAVED 3 HOMES , BLOCKS FROM THE RARITAN BAY ON THE JERSEY SHORE FROM FLOODING. KEPT US WARM AND MY MILK COLD. I CAN'T GIVE A LONG TERM REVIEW BEING I PICKED IT UP THE DAY OF THE HURRICANE. IT ALL READY PAID FOR ITSELF AS

Rated 5 out of 5 by from Starts and runs great We use it for back-up power and even after sitting for months, it starts on the first pull. During Hurricane Mathew, it powered our house for 7 days before power was restored. While the 5500 is adequate, it's borderline for powering the entire house and we need to watch what we're using at any one time. We have a 1800 sf home plus garage, barn and outbuildings. If I was to purchase it now, I would have gotten the 6500 or slightly larger. However, for emergency back-up it does a great job.

Rated 5 out of 5 by from Very simple to use, easy to move around!! I bought this unit under duress,(our power went out because of storms,my old generator,20 years old, would not start up,,started out with one problem and ended up with 3 problems when the fuel valve broke off in the tank!!!,5 hrs into no electricity!!) The wife sent me to the local Lawn Mower shop to buy a new one(generator). The ''Generac'' came home with me, and we saved our,and our 2 neighbors food.(3 refrigerators and 2 freezers)!!! NICE
