A standard 5 000 watt generator will consume around 18 gallons of gasoline during a 1 day 24 hour period.
Lp gas generator fuel consumption.
To compare that to gasoline 110 000 btu per gallon times the cost by 1 1 to arrive at 0 88 per gallon.
So if you are paying over 0 88 per gallon for gasoline you can save by using natural gas.
For example if a burner uses 22 875 btu per hour it will last 4 hours on a gallon of propane which contains 91 502 btu.
50 load 2500 watts output average should use no more than 50 000 btu per hour and cost approximately 0 40 to operate.
As for another example again depending on what you are powering and the size of your generator let s say 20kw in this example a propane generator may use around 2 3 gallons hour.
Most portable generators will run on gasoline out of convenience.
But just for shits and giggles let s give it a shot.
Calculating propane gas consumption is based on the burner size.
Typically a 50 amp generator burns at least one gallon of lp per hour while a 30 amp generator will consume about a half a gallon of lp per hour.
Propane gas consumption chart.
So if you have a 500 gallon tank which can only be filled to 400 gallons then a full tank would last you around 6 to 7 days.
A typical generator uses three quarters of gas gallons per hour.

These numbers are just estimates and each generator must be estimated for it s individual fuel consumption.
As you might know all generators are not created equals some will consume more and some others may use less than what was mentioned.
Gasoline prices are somewhat expensive and tend to be the least efficient way to run a generator.
