Why You Should Worry about your Generators Old Diesel Fuel

Diesel Fuel Gets Old Fast – 3 Months

Not like your car, fuel sits in a generator tank for a long time, because it is stored for when you need it.  Say you have a 300 KW generator and you want 8 hours of run time.  At full load you need 20 gallons per hour so you need a 160 gallon tank.  If you test your generator once a month for 15 minutes unloaded, you will use 7 gallons per hour 3 hours per year for a total of 21 gallons per year.  That means, without a big power outage, you would use all your fuel in about 8 years.
