Did you know that a semi truck can waste as much as 0.8 gallons of fuel an hour while idling? This can add up over time. Some trucks never shut down. Drivers may leave their trucks running for a few minutes while waiting at a loading dock or during a rest. If you calculate the fuel consumed by one truck per hour, you’ll notice that the fuel used by idling increases dramatically.
Many factors are involved in how much fuel a semi truck uses while idling, from the number of gears to aerodynamics. Proper route planning and using gears wisely can also reduce fuel use. Contact an International Used Truck Center for more information. Ultimately, the best way to maximize fuel efficiency is to know how much fuel your semi truck consumes while idling.
In the U.S. Department of Energy, idling a semi truck can waste as much as 0.8 gallons of fuel per hour. If a semi-truck sits idle for 10 hours, it will use eight gallons of fuel. This is equivalent to over $200 in fuel over the course of a year. Additionally, many states have passed laws against idling a semi-truck while it’s not in use. They want to curb emissions and the environmental impact of the trucks. However, if you break the laws, the fines can be quite large.
