Frequently Asked Questions

How much fuel does a truck typically burn while idling?

Fuel consumption varies considerably based on engine displacement, idle speed, ambient conditions, and accessories running. Light duty vehicles consume about 1.1 gallons per hour, while heavy duty vehicles can consume 1.25 gallons per hour or more.

How much CO2 is produced per gallon of fuel?

Diesel fuel produces approximately 22.4 pounds of CO2 per gallon, gasoline produces about 19.6 pounds per gallon, and gasoline with 10% ethanol produces around 18.2 pounds per gallon when burned.

What are ghost miles and how are they calculated?

Ghost miles represent the equivalent wear and tear on your vehicle from idling. On average, one hour of idle time equals approximately 30 miles of driving in terms of engine wear and maintenance requirements.

How are maintenance savings estimated?

Maintenance savings are calculated based on the additional wear from idling, including more frequent oil changes and accelerated engine overhaul schedules. Idling increases maintenance costs due to incomplete combustion and increased engine operating hours.

Why do CO2 emissions weigh more than the fuel itself?

During combustion, fuel combines with oxygen from the air to form CO2. The additional weight comes from the oxygen molecules that bond with the carbon in the fuel, resulting in CO2 emissions that weigh more than the original fuel.

What factors affect idle fuel consumption?

Several factors influence idle fuel consumption including engine size and efficiency, ambient temperature, use of air conditioning or heating, alternator load, power take-off usage, and other accessories drawing power from the engine.

How can idle reduction systems help save money?

Idle reduction systems can eliminate or significantly reduce idle time, saving on fuel costs, reducing maintenance expenses, extending engine life, and decreasing harmful emissions. Many systems pay for themselves within 1-2 years through fuel savings alone.
