Logbook Servicing 101: What It Covers and Why It Protects Your Warranty

If your car is still under its new-car warranty, the service book in the glovebox matters more than most owners realise. A logbook service is a service carried out to the schedule your car's manufacturer sets for its age and kilometres, with the work recorded so you can prove it later. Here's what a logbook service includes, why the list changes from one visit to the next, and what Australian consumer guidance says about where you can have it done.

What makes it a logbook service

Your car's maker publishes a service schedule, normally by kilometres and months, whichever comes first. Intervals differ between brands and models, and some manufacturers list a shorter schedule for harder use such as lots of short trips, towing or stop-start traffic. A logbook service follows the checklist for the interval your car has reached, uses parts and fluids that meet the manufacturer's specification, and is recorded in the service book or the maker's electronic service record.

That record is what separates a logbook service from a quick oil change. An oil change protects the engine. A logbook service also covers everything else listed for that interval and leaves a paper trail you can show a dealer, an insurer or the next buyer.

What a logbook service includes at most visits

The exact list comes from your service book, but most intervals include:

• Engine oil and oil filter replaced with the grade your manufacturer specifies
• Brakes inspected, including pads, discs, hoses and lines
• Fluid levels and condition: coolant, brake fluid, power steering and transmission fluid where it can be checked
• Tyres checked for tread depth, damage and pressure
• Steering and suspension components, including driveshaft boots
• Lights, horn, wipers and battery condition
• A road test, with anything that will need attention later written down

If the inspection turns up worn brake parts or a suspension problem, that's quoted separately so you can decide; see our brake and suspension repairs for what that work involves.

Items that only come up at certain intervals

This is where schedules differ most, and it's why two services on the same car can take different amounts of time. Depending on the interval, your book may call for:

• Cabin (pollen) filter and engine air filter replacement
• Spark plugs on petrol engines
• Brake fluid replacement, because brake fluid absorbs moisture over time
• Coolant replacement
• Transmission or differential fluid changes on some models
• Drive belt replacement, and timing belt replacement on engines that use one

Your service book shows which interval includes which item. When an item that's due gets skipped, the record shows that too, which is exactly what you don't want a warranty assessor to find.

Why kilometres alone don't tell the whole story

A car doing short school runs in Dandenong traffic every day can wear its oil and brakes faster than one that cruises the Monash Freeway once a week. That's why schedules count time as well as distance, and why the harder-use schedule exists. Batteries, hoses and rubber seals also age through Melbourne's hot summers whether the car moves or not. If most of your driving is short trips, towing or heavy traffic, ask whether your manufacturer's shorter schedule applies to you.

Can an independent workshop service it during the warranty?

The ACCC's guide for new car owners, Just bought a new car?, says a manufacturer's warranty "typically allows you to choose your preferred repairer for service and repair, as long as the manufacturer's maintenance and servicing standards are met." It also notes that some warranties may require you to return to the dealer network for repairs claimed under the warranty. In other words, routine servicing can generally be done by an independent workshop, while a warranty repair itself may still need to go back to the dealer.

Independent workshops also have better access to the technical information they need than they used to. A mandatory scheme requiring car makers to make service and repair information available to Australian repairers was set to start on 1 July 2022. The ACCC's page on new and second-hand cars also points out that voluntary warranties sit on top of your automatic consumer guarantee rights and can't take them away.

Three things protect you, wherever you service the car:

• The work matches the interval listed in your book
• Parts and fluids meet the manufacturer's specification
• Every service is recorded, with an itemised invoice of what was done

Keep the invoices with the book. If a warranty question comes up years later, a complete record is usually the quickest way to settle it.

What to bring, and what to ask for

Bring the service book, or tell us if your car uses an electronic service record. Mention any warning lights, noises, vibrations or leaks you've noticed, even if they come and go. Ask for an itemised invoice, and ask for anything found that isn't urgent to be noted so you can plan for it instead of being caught out.

Buying a used car? A complete logbook history is one of the first things to check, and a pre-purchase inspection tells you whether the car's condition matches its paperwork.
