What do you hear about idle time in the feeder dept? We are told to idle under 23 minutes. My objection is Mack has a sticker on the visor saying to idle the engine for 3 Min. before shutdown or turbo charger damage will occur. Aren't we shooting ourselves in the foot by decreasing idle times to help the "environment" (IMHO UPS's new flavor of the week/year according to the calendars) and save fuel-yet at the same time we are paying $ to replace the turbo? The other day, automotive supervisor and feeder dept supervisor were having a disagreement about this. One dept. benefits with low idle time, while the other gets stuck with the replacement cost. It all boils down to at least I don't have to pay for the repair bill. Just my 2 cents.
