What is a truck 15,000 km service?
A 15,000 km service is the first tier of scheduled preventive maintenance for a rigid truck, prime mover or heavy vehicle. It is performed every 15,000 kilometres (or per the manufacturer's service schedule) and is classified as a minor service. The procedure covers engine oil and filter replacement, air filter inspection, fuel system maintenance, coolant and drivetrain fluid level checks, driveline and chassis greasing, brake measurement, tyre inspection and torque, electrical system testing, exhaust and DPF inspection and cab safety checks. Unlike a daily pre-start check (which confirms the vehicle is safe to drive), the 15,000 km service involves actual maintenance actions: draining and replacing fluids, replacing filters, greasing components and measuring wear. It is typically performed by a qualified mechanic in a workshop.
Benefits of scheduled truck servicing
- Reduced breakdowns: regular oil, filter and fluid changes prevent engine and drivetrain failures that cause unplanned downtime and missed deliveries.
- Extended component life: clean oil and correct greasing reduce wear on engine, transmission, differentials and chassis components.
- Lower repair costs: a 15,000 km minor service costs a fraction of an emergency breakdown repair. Catching issues early prevents cascading damage.
- Driver safety: inspecting brakes, tyres, lights, seatbelts and exhaust systems at regular intervals reduces the risk of on-road incidents.
- Compliance: documented service records demonstrate that vehicles are maintained to NHVR, WHS and Chain of Responsibility standards, supporting insurance and regulatory obligations.
- Resale value: a complete service history with documented 15,000 km and 100,000 km services increases the vehicle's value at trade-in or auction.

Service actions included in the 15,000 km procedure
This service procedure covers 25 service actions across 7 system areas:
- Engine: drain and replace engine oil (15W-40 or 10W-40), replace oil filter, inspect air filter, drain fuel/water separator, check coolant, inspect exhaust/DPF, check AdBlue level, force DPF regen if required.
- Drivetrain: check transmission oil level, differential oil level and power steering fluid level.
- Lubrication: grease driveline (universal joints, slip yoke), grease king pins and steer axle, grease spring pins and shackles.
- Brakes: measure front and rear brake pad/shoe thickness.
- Wheels and tyres: check tyre pressures and tread depth all positions, torque wheel nuts to spec.
- Electrical: check battery terminals and charge, test all lights, test horn and reversing alarm/camera.
- Cab and safety: inspect seatbelts, check cab mounts, inspect windscreen and wipers.
Fluid specifications
General fluid specifications for rigid trucks and prime movers. Capacities vary by engine size and drivetrain configuration.
| System | Type / Grade | Approx. Capacity |
|---|---|---|
| Engine oil | 15W-40 or 10W-40 CI-4/CK-4 | 20 - 40 L |
| Coolant | 50/50 ethylene glycol | 30 - 50 L (system) |
| Transmission oil | Allison TES 295 or 80W-90 manual | 15 - 30 L (system) |
| Diff oil | 80W-140 or 85W-140 GL-5 | 8 - 15 L per diff |
| Power steering | ATF | As required |
| AdBlue / DEF | ISO 22241 | As required |
| Grease | EP2 lithium complex | As required |
Specifications are general guidelines. Always refer to the manufacturer's service manual for your specific make and model.
Parts and consumables
Have the following parts and consumables ready before starting the 15,000 km service:
- Engine oil (15W-40 or 10W-40 CI-4/CK-4) - 20-40 litres
- Engine oil filter - 1
- Fuel/water separator element - 1
- EP2 grease cartridges - 4-6
- AdBlue / DEF - as required (if fitted)
- Rags, drip tray and waste oil container
Look up part numbers in the manufacturer's parts manual for your specific make and model before ordering.
How to perform a truck 15,000 km service
- Park the truck on level ground, apply the park brake, chock the wheels and shut down the engine. Allow the engine to cool before draining oil.
- Record the vehicle details and current odometer reading at the top of the service procedure form.
- Start with the engine section: drain the old engine oil, replace the oil filter, fill with new oil to the correct level, then inspect the air filter, drain the fuel/water separator, check coolant, inspect the exhaust/DPF and check AdBlue level.
- Check drivetrain fluid levels: transmission oil, differential oil and power steering fluid. Top up if required.
- Grease all specified points: driveline universal joints and slip yoke, king pins and steer axle, spring pins and shackles. Use EP2 lithium complex grease.
- Measure front and rear brake pad/shoe thickness. Record the measurements in the notes column.
- Check tyre pressures and tread depth all positions. Torque all wheel nuts to the manufacturer's specification.
- Check the battery, test all lights, test the horn and reversing alarm, inspect seatbelts, check cab mounts and windscreen.
- Start the engine and check for leaks, abnormal noises or warning lights. Record any defects or recommendations in the notes section.
- Set the next service due kilometres (next 15,000 km and next 100,000 km intervals). Sign off and update the vehicle's maintenance log.

Truck maintenance follows a tiered schedule where each level includes all tasks from the level below. This is called carry-forward or cumulative servicing.
15,000 km - Minor service (you are here)
Engine oil and filter, grease driveline and chassis, fluid level checks, brake measurement, tyres, lights, DPF and AdBlue. Estimated 2-3 hours.
All 15,000 km tasks plus coolant flush, transmission oil, differential oil, full brake reline, wheel bearings, fan belts, valve clearance, injectors, chassis inspection and air system service. Estimated 6-10 hours.
In MapTrack, you can configure service schedules by odometer readings and receive automatic alerts when each interval is due.
Frequently asked questions
- What is included in a truck 15,000 km service?
- A 15,000 km truck service is a minor service that includes draining and replacing engine oil (15W-40 or 10W-40), replacing the engine oil filter, inspecting the air filter, draining the fuel/water separator, checking coolant level, checking transmission and differential oil levels, greasing the driveline (universal joints, slip yoke), greasing king pins, steer axle, spring pins and shackles, measuring front and rear brake pad/shoe thickness, checking tyre pressures and tread depth, torquing wheel nuts, checking the battery, testing all lights, testing the horn and reversing alarm, inspecting the exhaust system and DPF, checking AdBlue level, inspecting seatbelts, cab mounts and windscreen. It takes approximately 2 to 3 hours.
- How often should a truck be serviced?
- Trucks and heavy vehicles follow a tiered service schedule based on kilometres. A 15,000 km (minor) service covers oil, filters, grease and basic inspections. A 100,000 km (major) service adds coolant flush, transmission oil, differential oil, full brake reline, wheel bearings, fan belts, valve clearance, injectors and chassis inspection. Daily pre-start checks are performed by the driver before each shift. Always refer to the manufacturer service manual for your specific make and model.
- What oil goes in a truck engine?
- Most heavy vehicle diesel engines use 15W-40 or 10W-40 engine oil meeting CI-4 or CK-4 specifications. Typical engine oil capacity for a rigid truck or prime mover is 20-40 litres depending on engine size. Some manufacturers specify different grades for extreme conditions. Always check the service manual for your specific make, model and operating environment.
