Can a Mobile Mechanic Do a Logbook Service? (And Keep Your Warranty?)

It's the most common question we get from new customers with cars still under manufacturer warranty: "If I use a mobile mechanic instead of the dealership, will I void my warranty?"

The short answer is no — and Australian law is firmly on your side. Here's the full picture.

Under the Australian Consumer Law (ACL) and the Competition and Consumer Act 2010, car manufacturers cannot legally require you to use their authorised dealership for routine servicing in order to maintain your warranty.

This was clarified definitively by the Australian Competition and Consumer Commission (ACCC). The key principle: a manufacturer can only void your warranty if they can prove that the service or repair caused the defect you're claiming under warranty.

In plain terms: if you use a qualified mechanic who follows the manufacturer's service schedule and uses OEM-spec or equivalent parts, your warranty is intact. Full stop.

A logbook service isn't a single fixed procedure — it's a service completed to the manufacturer's specified schedule for your vehicle's make, model, and current odometer reading.

That schedule typically includes:

• Engine oil and filter change — to the manufacturer's specified grade and capacity
• Air filter inspection/replacement — at specified intervals
• Cabin filter replacement — at specified intervals
• Spark plug inspection/replacement — at specified intervals (petrol engines)
• Brake fluid check — and replacement at specified intervals
• Coolant level and condition check
• Tyre pressure and condition check
• All fluid top-ups — power steering, windscreen washer, etc.
• Visual inspection — belts, hoses, battery, lights, suspension components
• Logbook stamp — recording the date, odometer, and work completed

The specific items vary by vehicle and service interval (e.g., 10,000km vs 15,000km services have different requirements). A qualified mechanic pulls this schedule from the manufacturer's service data before arriving.

Here's exactly what happens when you book a logbook service with Autova:

When you book, we take your rego number. We use this to pull your exact vehicle spec — make, model, year, engine type, and current service interval requirements. This tells us:

• The correct oil grade and capacity
• Which filters are due
• Whether spark plugs are on this service
• Any model-specific requirements or known issues

We order and load all required parts before we leave base. When we arrive at your driveway, everything needed for your specific service is already in the van. No "we'll need to order that part" delays.

Every item on the manufacturer's service checklist for your vehicle and interval is completed. We use OEM-spec or equivalent parts — the same standard required to maintain your warranty.

Your logbook is stamped with the date, odometer reading, and the mechanic's details. This is the documentation that proves the service was completed — it's what protects your warranty and what you'll need if you ever make a warranty claim.

You receive a written service record detailing everything completed, all parts used (with part numbers), and the next service due date and odometer.

You'll see this phrase in warranty documentation. Here's what it means in practice:

OEM (Original Equipment Manufacturer) parts are the exact parts the manufacturer uses in production — or their branded aftermarket equivalent (e.g., genuine Toyota oil filter).

"Or equivalent" means parts that meet or exceed the OEM specification — same dimensions, same materials, same performance rating. Reputable aftermarket brands like Ryco (filters), Penrite (oils), and Bosch (spark plugs) are widely accepted as equivalent.

What's NOT acceptable: cheap no-name parts that don't meet spec, incorrect oil grade, or wrong filter dimensions. These are the things that could actually give a manufacturer grounds to dispute a warranty claim.

Autova uses quality aftermarket parts that meet manufacturer specifications on every service.

Many car owners believe they must use the dealership for warranty services. This belief is actively encouraged by dealerships — it's profitable for them. But it's not legally accurate.

The ACCC has specifically warned manufacturers against implying that warranty coverage requires dealership servicing. If a manufacturer or dealer tells you that using an independent mechanic voids your warranty, ask them to put that in writing. They won't — because it's not true.

The only scenario where a manufacturer can legitimately void a warranty is if they can demonstrate that a specific repair or service directly caused the defect being claimed. Routine logbook servicing with correct parts and procedures cannot cause a defect.

To protect yourself in the unlikely event of a warranty dispute, keep:

1. Your stamped logbook — the primary record of all services
2. Written service records from each service — detailing work done and parts used
3. Receipts for parts — showing the parts used met manufacturer spec

Autova provides a written service record after every logbook service. Keep these with your logbook.

• Your car is under warranty — and you want the peace of mind that comes from knowing the service is done correctly and documented properly
