Standby generators provide emergency power to homes and businesses when required. But what happens if (and when) the standby generator fuel goes bad?
How long can you leave fuel in a generator?

Does generator fuel go bad?
The answer is that it depends on the type of fuel being used. If you are using standby generators that run on petrol or diesel, then the fuel will go bad over time and will need to be replaced. However, if you are using a standby generator that runs on natural gas or propane, it will last longer.
