Fleet Maintenance Product Guide

ComfortGuard APU

Cummins Inc. has doubled the oil change interval from 500 hours to 1,000 hours for its ComfortGuard Auxiliary Power Unit (APU), which will improve uptime for truck and fleet owners while cutting maintenance costs in half. The recommendation comes after extensive testing in conjunction with the engine supplier, Kubota, to ensure there was no degradation in performance or longevity.
