How often should a generator be serviced? At a minimum, a generator should be serviced by a professional at least once a year and the oil & filters changed during that time. Depending on the quality and size of your standby generator service, most manufacturers usually predict that a standby generator will remain reliable anywhere from 10,000 - 30,000 running hours (about 25 - 40 years) depending on how well it is maintained. If you leave your generator unattended for a while, chances of it developing fuel problems are too high. Without maintenance, a generator can become the flourishing ground of algae and fungi. And it can even get clogged injector or its batteries can even leak.
