Excessive regens - A number of our customers who use their trucks for work complain about very frequent regens that kill their fuel mileage and satisfaction. Many customers who work outdoors in the wintertime were would leaving their old diesels run for hours on end while they were on career openings site. The DPF equipped trucks don't handle this very highly. The cooler idling temperature for this exhaust gas will soot up the DPF on an accelerated payment. It is not uncommon as a result of customers to on their second or third filter change ever since the Bulk Feed Truck went into constant limp mode. The usually dealership response is: "You can't let these new trucks idle." Which matches over as good as with guys who are stuck attending the job site five miles back a woods all day and special Vehicle the temperature never gets above ten stages.
