If your truck carries weight or tows, the maintenance schedule you should be reading is the severe-duty column — not the normal one. That's most of what rolls in from Tewksbury.
What Oil Changes & Preventive Maintenance Covers
- Conventional, synthetic blend, and full synthetic options
- OEM-spec oil filter replacement
- Multi-point inspection at every service
- Fluid top-offs (washer, coolant, brake)
- Tire pressure check & visual brake inspection
Load raises combustion and oil temperatures and keeps them there. Hot oil oxidizes faster, so the interval that's correct for an unloaded commuter is optimistic for a loaded pickup or a van full of equipment. Manufacturers publish a severe-duty schedule for exactly this reason, and it's the honest one for working vehicles.
Idling counts too. Time spent running at a job site puts hours on the engine that the odometer never records, which is one reason fleet operators track engine hours as well as miles.
Boston Fleet Services maintains commercial vehicles on that basis every day; your truck gets the same approach. Call for current pricing.
Tewksbury Questions About Oil Changes & Preventive Maintenance
- Should my work truck be on the severe-duty oil schedule?
- If you regularly carry load, tow, or idle at job sites, yes. Those conditions raise oil temperature and shorten its life compared with the normal-duty assumptions.
- Does idling on site affect my oil interval?
- It does. Idle time accumulates engine hours and heat without adding miles, so a truck that idles a lot reaches the end of its oil life earlier than its odometer suggests.
