Fleet Maintenance FAQ — New Castle, Delaware

What should a preventive maintenance program for a small diesel fleet include?
At minimum: oil and filter service on the manufacturer's hour or mile interval, fuel and air filters, coolant testing, brake and tire inspection, greasing, DEF system checks, and a look at the aftertreatment history. Add the annual DOT inspection for commercial vehicles. A good New Castle fleet shop puts this on a calendar per unit and sends reminders so nothing slips.
How do fleet accounts work with New Castle diesel shops?
Most fleet shops offer net-30 billing, a single monthly statement, and a negotiated labor rate once you commit a few units. Some include priority scheduling and a loaner or shuttle. Ask what the minimum fleet size is — in New Castle that is often as low as three vehicles — and whether they will keep digital service records you can pull for audits.
Is it better to use one shop for everything or split engine, brakes, and trailers between specialists?
For a small fleet, one shop that can do 90 percent of the work — PMs, brakes, electrical, emissions, inspections — is simpler and keeps records in one place. Send the rare rebuild or reefer job to a specialist. Larger Delaware fleets often keep one general fleet shop plus a dedicated trailer and reefer vendor.
What records does Delaware or the DOT expect me to keep for my trucks?
Commercial motor vehicles need a maintenance file per unit showing inspections, repairs, and the annual inspection report, retained for at least a year while the vehicle is in service and six months after. Driver vehicle inspection reports and defect repairs go in the same file. Fleet shops in New Castle that work with carriers usually hand you paperwork formatted for exactly this.
Can a fleet shop maintain the diesel pickups and vans in my fleet as well as the big trucks?
Yes, and most prefer it — pickups, service vans, and medium-duty trucks are the bulk of many New Castle fleet shops' work. Confirm they carry the scan tools for your engine families (Power Stroke, Cummins, Duramax, plus any Isuzu or Hino cabovers) and that they can handle warranty-compliant service intervals on newer units.
