How long can a generator run?

There are two ways to find out how long a generator can run. The first one is by checking the manufacturer’s specifications, and the second way is by checking with your friends.

Many things affect the running time of generators like:

  • Cold weather (when it is cold outside, the engine will slow down because of less heat generated inside)
  • High humidity (high humidity means less air gets pulled into the engine) and other stuff. Also, check out how much fuel you put in and whether it was new or old.
  • A generator with more fuel will run longer than one without fuel because it needs more time to warm up before generating power.
  • A generator that runs on used oil can produce energy for longer than one using new oil if they were both filled with the same amount of oil before being placed in use.

So, make sure you think about all these factors when you’re picking a generator.
