PIB TIP: CONSIDER AN APU. A recent survey shows the average owner-operator idles more than 5 hours a day, in all weathers. That’s the equivalent of 18,000 yearly miles on the engine, says Argonne National Laboratory. Cutting that idling to zero eliminates 18,000 miles of wear, extends your oil-drain interval and saves nearly $4,500 in fuel costs with diesel at $3 a gallon. The Partners in Business program is produced by Overdrive and the consultants at ATBS, the nation’s largest owner-operator business services firm, and is sponsored by Schneider National Inc. and Freightliner Trucks.
