Fuel & Energy — Idle Time Cost
Idle Time Cost for equipment fleet management.
Idle burns more than fuel — it burns warranty hours, service intervals and resale value, all indexed to the hour meter. A machine idling 30% effectively ages 30% faster than its work output justifies; auto-idle shutdown timers pay back in weeks.
