I bought this generator about 4 years ago brand new. Its sole purpose was to be used in case of power outages, which have not happened. I have run the engine 4 times a year, for about 20 minutes at a time, just as preventative maintenance. If my math is correct, that means it has less than 10 hours of service on it. Garage kept, in like new condition, with some minor cosmetic blemishes in places.
