The fuel consumption of a diesel generator depends on its size, power output and load. On average, a diesel generator uses about 0.4 to 0.8 gallons of fuel per hour for every 10 kilowatts (kW) of power produced. To estimate the fuel usage for your generator, consult the manufacturer's specifications or contact our team for additional information.
When comparing diesel-fueled generators to propane-powered generators, there are various factors to consider, including emissions, fuel costs, convenience and more. Learn all about the pros and cons of propane versus diesel generators in our Project Uptime article.
Diesel generators are often equipped with a 24-hour fuel tank, and some even come with a 48- to 72-hour tank. Speak with a United Rentals representative to determine what capacity tank you need from your generator rental. Make sure to closely follow all safety guidelines and keep generators positioned outside and away from open windows to prevent dangerous levels of carbon monoxide from entering any homes or businesses.
