How much does idling cost a trucker?
A diesel engine at idle burns approximately 0.8 gallons per hour. At $3.80/gallon, that's $3.04/hour. Overnight idling for 8 hours (for climate control) costs $24 per night, or about $7,200/year if you idle every night. APU (Auxiliary Power Unit) units cost $8,000–12,000 installed but pay for themselves in 1–2 years for drivers who sleep in their truck regularly.
